Abstract
The invention particularly provides a simulation installation and site construction method for a steel column with a radial spherical plain bearing. The method is characterized by comprising the steps that an integral structure construction process analysis model is built through finite element analysis software, and a software analysis stage is defined and a corresponding construction load is applied according to the steel structure construction steps; an annual average temperature value of the construction location is inquired to serve as a temperature parameter of software analysis; a steel column installation stage is analyzed; when site construction is conducted, a column bottom joint of the steel column is installed according to originally designed coordinates, and a predeformation value is applied when a column top joint is installed; steel structure installation is organized according to the simulation analysis step, so that after the structure generates displacement, the column top joint of the steel column infinitely approaches to the designed coordinate position under the average temperature condition.
Description
Technical field
The present invention relates to field of steel structure construction, specifically a kind of installation of the simulation with plain radial bearing steel column and scene
Construction method.
Background technology
For large-span space structure, for release temperature deformation and stress, typically can be in end setting some of encorbelmenting
Swing column, i.e. two ends hinged steel stanchion.Under regular situation, two ends be may require that according to steel when mounted using the steel column being articulated and connected
Post design locus are positioned, because the change of load and temperature action affect to lead to after seldom considering steel column installation
Structure is subjected to displacement, and the situation of steel column upper and lower end parts node off-design coordinate position.When steel column end employ centripetal
After oscillating bearing, because oscillating bearing allows the outer amount of spin of the plane of specified value, if still being installed according to prior art, ask
Topic is just more prominent:
1st, after temporary supporting system unloading, roof structure can produce horizontal displacement, drive steel column to deflect, lead to oscillating bearing
Just there is certain deflection angle when using original state it is impossible to the Double-directional rotary amount being fully achieved original design permission will
Ask.If unloading after horizontal displacement excessive in some instances it may even be possible to oscillating bearing occur block the situation it is impossible to freely rotatable, change former
The design work state of structure.
2nd, plain radial bearing cannot meet the burst size of malformation when building operational phase rises gentle cooling simultaneously.
3rd, serviceability limit stage, the initial position disalignment at plain radial bearing, impact structure is in operational phase
Architectural effect.
Content of the invention
It is an object of the invention to, provide a kind of installation method with plain radial bearing steel column, it can overcome existing peace
Deficiency existing for dress method.
In order to achieve the above object, the present invention is achieved in that
A kind of simulation installation with plain radial bearing steel column and component on site construction method, including
Step 1, set up structure construction procedure unitary analysiss model by finite element analysis software, fixed according to Construction of Steel Structure step
The adopted software analysis stage simultaneously applies corresponding construction loads；
Step 2, the inquiry local average temperature of the whole year value of construction, as the temperature parameter of software analysis；
Step 3, steel column erection stage is analyzed, pivoting support is pressed as constraint in steel column bottom, and steel column top applies two
Horizontal direction constrains, and tentative capital node coordinate is pressed design coordinate and installed, through whole range analysis, until having applied use rank
Section load, the y drawing capital node, to deviant, now gives tacit consent to vertical plain radial bearing connection otic placode plane；
When step 4, site operation, the post coxopodite point of steel column is installed according to original design coordinate, applies one during capital node installation
Predeformation value, predeformation value is the y of the capital node drawing according to theory analysis to deviant；
Step 5, according to sunykatuib analyses step tissue Steel Structure Installation so that after structure is subjected to displacement, the capital node of steel column exists
During temperature on average condition, infinite approach designs coordinate position.
The cardinal principle of this construction method is by work progress entirety sunykatuib analyses, drawing structure installation and facing
When support unloading after the displacement that produces of steel column top, and the displacement that the lower steel column top of roof load effect occurs, as according to
According to, preset value when determining that roof structure and steel column are installed it is ensured that steel column normal using and average temperature condition under, capital section
Point and plain radial bearing are in design attitude.
Brief description
Fig. 1 is the step schematic diagram of this construction method.
Specific embodiment
Further illustrate the present invention below by way of specific embodiment.
As shown in figure 1, a kind of simulation installation with plain radial bearing steel column and component on site construction method, including
Step 1, set up structure construction procedure unitary analysiss model by finite element analysis software, fixed according to Construction of Steel Structure step
The adopted software analysis stage simultaneously applies corresponding construction loads；
Step 2, the inquiry local average temperature of the whole year value of construction, as the temperature parameter of software analysis；
Step 3, steel column erection stage is analyzed, pivoting support is pressed as constraint in steel column bottom, and steel column top applies two
Horizontal direction constrains, and tentative capital node coordinate is pressed design coordinate and installed, through whole range analysis, until having applied use rank
Section load, the y drawing capital node, to deviant, now gives tacit consent to vertical plain radial bearing connection otic placode plane；
When step 4, site operation, the post coxopodite point of steel column is installed according to original design coordinate, applies one during capital node installation
Predeformation value, predeformation value is the y of the capital node drawing according to theory analysis to deviant；
Step 5, according to sunykatuib analyses step tissue Steel Structure Installation so that after structure is subjected to displacement, the capital node of steel column exists
During temperature on average condition, infinite approach designs coordinate position.
Compared with existing construction method, advantage is this construction method:
1st, after construction forming the deformation of structure and stress and original design state closer to being conducive to release temperature change to produce
Additional stress；
2nd, can keep in the most of the time, oscillating bearing otic placode is in center, architectural image effect is more preferable.
