Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the invention pertains.
Example 1
A tuned liquid damper water tank assembly, as shown in fig. 1-3, comprising:
the TSD box body is irregular in shape, a waterproof layer is arranged on the inner wall of the TSD box body, a drainage pipeline is arranged at the bottom of the TSD box body, and a water injection pipeline is arranged at a position above the static fluid depth of the TSD box body; it should be noted that as the main components of the system, the rigid TSD tank is generally constructed of concrete, and the internal dimensions and liquid height of the TSD tank are selected according to the desired liquid sloshing frequency; the inner wall of the TSD box body must adopt a waterproof layer to ensure that no leakage occurs; structural frequency measurements must be made before the TSD box is cast to finalize the dimensions of the TSD box (e.g., shorten the TSD box if the structural frequency is higher than expected), and as late as possible to provide the most accurate expected as-built frequency; the size of the drainage pipeline must be sufficient to enable the tank to be emptied within a certain period of time (e.g., several hours), if the drainage pipeline is connected with a drainage pipeline of a building, it is ensured that the drainage does not interfere with the normal pipe system of the building, and if the drainage pipeline is too large, a large pressure may be generated on the pipe of the building, which causes the backflow of water; the water injection line must be able to fill within a certain time (e.g., hours) to make unscheduled maintenance operational;
the TSD box body is divided into an effective water area and an ineffective water area by the partition plate, the partition plate is a steel structure plate and is provided with a plurality of holes, and the holes are used for communicating the effective (shaking) water area and the ineffective water area so as to ensure that all water in the water tank can be discharged when a fire occurs; it should be noted that the final tuning is to adjust the natural frequency of the sloshing by adjusting the static water depth of the water tanks, and since fire fighting requires at least 3.6m of water depth of each water tank, a horizontal partition is designed to ensure the minimum depth without affecting the tuning of the water tanks (when the effective water depth is required to be less than 3.6 m);
the support frame is formed by overlapping frames, a support column is arranged on each frame and used for supporting the partition plate, an embedded part is arranged at the edge of each frame and fixedly connected with the side wall of the TSD box body, and the embedded parts are connected with the frames through connecting plates;
the device comprises a TSD box body, a plurality of columns, a baffle plate and a frame, wherein the TSD box body is provided with a box bottom, the box bottom is provided with a box top, the box top is provided with a plurality of columns, the columns are arranged in a grid mode, the top end of each column is connected with the box top of the TSD box body, the lower end of each column penetrates through the baffle plate and the frame, and a space is reserved between each column and the box bottom and is used for providing fluid resistance for increasing turbulence consumed energy; the width of the paddle column is adjustable; it should be noted that, as the liquid shakes in the box body, the paddle column generates liquid resistance and consumes shaking energy; the final width of the column is not determined until final tuning and commissioning and is therefore designed to be adjustable. In particular, bolted connections may be used, the bolts not being fully tightened at this initial installation stage, and the final configuration of the paddles determined after TSD tuning and commissioning as soon as the building is completed.
In this embodiment, the water level in the TSD tank is below 1/2 for the specified fill depth. It should be noted that too high or too low a water level in the TSD tank may cause the tank assembly to fail. For most TDS systems, the actual depth should be 1/2 below the specified fill depth. Depth may be measured using dipsticks and the like or may be measured using a Building Management System (BMS) that is a combination of time-averaged sensor bundles. Overfilling of the tank will cause the building to bear additional gravitational and lateral loads that are of concern in the design. Can set up high water level alarm in TSD water tank inside, if the water injection pipeline is forgotten after retaining and is closed, can in time remind the staff in the building. In addition, overfill protection (e.g., standpipes) can be used to drain excess water that may be caused by a water injection line forgetting to shut down. The drainage capacity of all overfill protection should be greater than the filling capacity of the water injection line.
In this embodiment, the baffle has two openings at each end or near the middle.
In this embodiment, a seal or gasket is provided between the edge of the baffle and the inside wall of the TSD tank to prevent water from flowing past the edge of the baffle.
In this embodiment, the material of the waterproof layer is preferably 2K-PUR made of polyurethane resin. For the waterproof layer of easy to assemble, the oar post hangs at the box top, keeps the oar post bottom and TSD bottom of the case portion to leave the interval, and in any position in the box, it can make the risk that the gap leaks to reduce to minimum to guarantee to permeate to be less than the still water degree of depth. In addition, a waterproofing membrane may be provided on the exterior of the TSD box and may be drawn into the interior of the building, for example if the TSD box is to be built on top of a building, the waterproofing membrane may be installed before the box is installed on the roof. If the TSD box leaks, the waterproof membrane can prevent water from entering the building.
In this embodiment, the present invention is characterized in that: the TSD tank is provided with a manhole at the top or above the maximum expected static liquid depth to ensure that no significant water leakage occurs when the hatch door is opened, the manhole being used for periodic inspection and maintenance of the TSD.
It should be noted that if the frequency of the completed structure is higher than the nominal frequency, as shown in fig. 6 to 8, the tank needs to be shortened by a partition wall for shaping the TSD casing to facilitate proper liquid sloshing by the TSD, the partition wall dividing the entire casing into an effective portion and an ineffective portion which are communicated through a hole formed in the partition wall to ensure that all the water in the tank is discharged in the event of a fire.
In this embodiment, the water tank subassembly still includes the leak hunting system, the leak hunting system includes monitor probe, sensor and alarm, inside TSD box was located to monitor probe for detect the wave effect in water level decline and the adjusting box, below or the side of TSD box surface is located to the sensor for monitor water leaks the surface, the alarm is used for sending and maintains the warning.
It should be noted that frequency measurements of as-built construction are critical to predict the final as-built frequency. This work requires the structural engineer to predict the frequency of construction for the condition of the construction. Careful coordination is required to ensure that the baffle and partition walls of the TSD tank are properly positioned.
In general, the position of the TSD box is selected to minimize the influence on the building when a leak occurs. Preferably, the TSD box will be mounted on the roof level and if a leak occurs, the liquid in the TSD box will be dumped onto the roof, allowing it to drain through the roof drain as if it were rain. In other cases, it may be installed in a location where the leak can be directed to drain before it affects the building.
Example 2 System kinetic analysis
1. Structural model
The equation of motion of the entire vibration system can be expressed in the form of the following matrix:
wherein:
x is an index representing interlayer shift (x)nAnd yn) And torsion (r)zn) A displacement vector;
[ M ] is a matrix comprising the mass and the mass moment of inertia (adjusted according to vector x) of each layer;
[C] the matrix is a diagonal strip matrix, is basically a chain structure and comprises proper damping characteristics of a building model;
[K] a diagonal strip matrix, similar to the damping matrix, gives the return tendency (stiffness) of the building and SDS;
{FSDS(x) Is the vector of the nonlinear coupling damping force between the SDS floor and the SDS, as a transient function of x;
{Fenv(t) is the force vector of the environment acting on the building and the SDS system, and the wind load and the earthquake load are different, and the concrete is as follows:
for wind load, generalized force is calculated from time-course data of wind tunnel test. These forces act on each time step in the simulation;
for seismic loads, the reference system is fixed to the ground floor of the building. Therefore, according to the D 'Alembert's principle, the load is distributed according to a coordinate system, and the load acts on the translation direction of each layer.
The system of equations is then substituted into a state space form that has twice the number of first order differential equations as compared to the original second order differential equation set. This is done to facilitate the transfer of the numerically integrated program state variables (typically displacement and velocity are initially zero) at each step of the numerical integration step. The commonly used fourth-order Runge-Kutta-Gill method is used, taking into account the combination of desired accuracy and computation speed.
2. Shaking liquid model
The irregular shaped TSD tanks require advanced simulation techniques to predict the dynamic characteristics of the sloshing water to determine the interaction of the TSD with the structure. The water sloshing is predicted by combining nonlinear simulation and a simplified finite element technology. Finite element methods are used to predict the water sloshing mode, representing the shape of the free liquid surface (wave). By superimposing all sloshing modes (the 6 th order mode is considered in this analysis), the overall response of the water sloshing can be determined.
Fig. 5 illustrates a front six-step sloshing mode shape of the TSD tank assembly shown in fig. 1, and fig. 9 illustrates a front six-step sloshing mode shape of the TSD tank assembly shown in fig. 6.
Example 3
1. Purpose(s) to
The scale test of a tuned liquid damper (TSD) was performed to verify the dynamic behavior of sloshing water in an irregularly shaped TSD tank.
2. Test set-up
The reduced-scale TSD water tank is made of transparent resin glass with the thickness of 13 mm;
the TSD water tank comprises a partition plate made of resin glass with the thickness of 13mm, the partition plate is fixed by silica gel, a distance of 55mm is reserved from the bottom of the TSD water tank, and holes with the thickness of 9mm and 13mm are drilled on the partition plate and used as holes for discharging water in case of fire;
the TSD water tank is equipped with 7 columns to increase the fluid resistance and thus improve the damping of the sloshing water. The columns are extended into the water from the top, and three groups of widths are tested by 7 columns, wherein the widths are respectively 18mm, 34mm and 52 mm;
3. testing device
The reduced-scale TSD waterbox is mounted on a single-axis shaker table and is subject to pre-designed substrate motion. The oscillating table imparts a simple harmonic motion with a constant displacement amplitude and a series of specific frequencies (cycles per second). A frequency sweep is performed with a frequency that varies in the vicinity of the expected natural frequency of the oscillation. At each frequency, the sloshing response of the water was brought to a steady state and the response data for 105s was recorded. The following response values were recorded: the nonlinear model can be verified by applying response values of water tank displacement (mm), water tank acceleration (m/s2), water tank base shear force (N) in the motion direction (X-direction), water tank base shear force (N) perpendicular to the motion direction (Y-direction), wave height (mm) and propeller column stress (N).
4. As a result, the
Fig. 10 to 12 show frequency response plots of peak height, X and Y direction shaking forces (corresponding to the direction of motion of the vibration table and its vertical direction) at several column sizes, vibration amplitudes and water depths. The measured and predicted results were relatively consistent and acceptable, indicating that the model used was able to simulate the TSD response.
Example 4
In contrast to the experimental setup of example 3, the vibration table test in this example included a baffle in the TSD box. The baffle is to ensure that the TSD is tuned to the completion frequency of the structure while maintaining a minimum water level of 3.6m required for fire protection. The clapboard is positioned at the position 55mm above the box bottom (the full scale is 1200mm), and each end of the box body or the position close to the middle of the box body is provided with two openings 9mm or 13 mm.
Figure 13 shows the measured sloshing forces in the excitation direction for different opening sizes when the opening is located at the end of the TSD tank. The resonance wobble frequency (peak of the response curve) occurs at a slightly higher frequency as the open hole size increases. The opening adds some damping to the sloshing liquid as the peak response decreases with increasing opening size.
Figure 14 shows the measured sway force in the excitation direction for different cut sizes as the cut approaches the middle of the TSD box. The sloshing liquid is not affected by the baffle. Thus, any openings in the baffle required for drainage should be near the middle of the TSD box. A seal or gasket should be provided around the perimeter of the baffle to prevent water from passing between the baffle and the internal wall of the TSD tank.
This embodiment is through confirming the test of baffle (having the fire control drainage function and opening the hole) influence, finds that if open the hole and be close to in the middle of the box then the baffle does not influence and rock the response, if open the hole and be close to the box tip, then rock the frequency and will improve slightly, and rock the inherent damping of water and will increase by a wide margin. Thus, a hole near the middle of the housing is a preferred embodiment.
Example 5
The tuning liquid damper water tank assembly provided by the invention has multiple functions including fire fighting and domestic water supply, and attention needs to be paid to the following:
1. fire fighting
Fire protection systems typically require design redundancy and, therefore, typically require more than one enclosure. If a one-way TSD enclosure is used (i.e. the enclosure inhibits movement of the building in one direction only, such as in the north-south direction), the enclosure can be subdivided in the main direction of movement of the building, creating two separate compartments within the enclosure to meet the need for redundancy.
The minimum water requirement meets the corresponding fire protection regulations. In addition, there may be a requirement in the fire codes for a maximum amount of water, wherein the maximum volume that can be stored in each tank is defined. And finally, after the finally determined water depth of the box body is constructed (including the inside), debugging and optimizing are carried out to obtain the finally determined water depth of the box body.
The hydraulic pressure in the fire protection system is required to be at the same level as the hydraulic pressure in the tank and to fill to the usual depth.
2. Domestic water supply
There is a minimum water requirement for the TSD tank for domestic water supply. And finally, after the finally determined water depth of the box body is constructed (including the inside), debugging and optimizing are carried out to obtain the finally determined water depth of the box body.
If the tank is to be used for domestic water supply, all surface materials must be compatible with this use. Therefore, a product must be selected that meets the domestic water requirements, the column must be coated with a protective anti-corrosion layer that meets food grade standards, and the use of stainless steel as the construction material for the column can meet food grade requirements while avoiding corrosion problems at the joints.
The TSD tank must have an appropriate depth of water to ensure proper operation of the damper. The acceptable water depth fluctuation range is different for each different project, and the fluctuation range of a few centimeters can be used as a reasonable initial estimation on the basis of the proposed still water depth considering that the water depth fluctuation cannot be avoided in the project. This may cause the filling pump to be switched on and off more frequently than the MEP system for the domestic water supply tank. The level gauge used to control the on/off of the filling line must be able to accommodate variations in the final filling depth of the tank. After the construction is completed, the adjustment and optimization are carried out, and then the acceptable range of the water depth change can be obtained. Furthermore, the tank can be shaken, that is to say, wave action can occur in the tank. The water level gauge must be able to cope with this wave action, it being possible to calculate the water level average by reading the data for several minutes.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
