Detailed description of the invention
Embodiments of the present invention are described in detail below in conjunction with drawings and Examples.
As it is shown in figure 1, the facade position view that can operate with for the present invention in structural system.Wherein, reinforce Seismic Isolation of Isolation Layer, basement and all may be disposed so that Seismic Isolation of Isolation Layer 6, form Interlayer seismic isolation or base isolation layer respectively.
As shown in Figures 2 and 3, Seismic Isolation of Isolation Layer of the present invention includes upper and lower superstructure, arranges the C-shaped shell Self-resetting parallel column 3 of a number of high strength and high flexibility large deformation, prefabricated replaceable concrete frame the first defence line support column 1, prefabricated replaceable concrete frame secondary defense support column 2 and energy-consumption shock-absorption device 4 between upper and lower superstructure.
Wherein, upper and lower superstructure by the X being crisscross arranged to and Y-direction primary and secondary beam body composition, and the position of upper and lower layer primary and secondary beam is unanimous between the higher and lower levels.Prefabricated replaceable concrete frame the first defence line support column 1 is arranged in four corner positions of Seismic Isolation of Isolation Layer periphery girder, prefabricated replaceable concrete frame secondary defense support column 2 and C-shaped shell Self-resetting parallel column 3 are arranged in the intersection of primary and secondary beam body, and are alternately arranged.C-shaped shell Self-resetting parallel column 3 and energy-consumption shock-absorption device 4 are arranged in the horizontal intersection of X, Y-direction primary and secondary beam body, X to and Y-direction, C-shaped shell Self-resetting parallel column 3 and energy-consumption shock-absorption device 4 are all alternately arranged.Energy-consumption shock-absorption device 4 is also arranged on primary and secondary beam simultaneously.
As shown in Figure 4, C-shaped shell Self-resetting parallel column 3 is connected in parallel by multiple C-shaped shells 31 and forms, C-shaped shell 31 adopts High performance carbon structural steels to make, the two ends of each C-shaped shell 31 are connected each through bolt or the C shape rib that is welded on cap, described C-shaped shell 31 is cross section is the steel of C shape, and the C shape radian direction of each C-shaped shell 31 of same C-shaped shell Self-resetting parallel column 3 is consistent.
C-shaped shell Self-resetting parallel column 3 has vertical loading specific stiffness and bearing capacity greatly, and its lateral anti-side rigidity is smaller, has certain level deformability, and still can remain elastic stage after vertical large deformation, and has certain Self-resetting performance.
Prefabricated replaceable concrete frame the first defence line support column 1 is prefabricated reinforced concrete column, reinforcing bar and styletable Plate Welding in post, the horizontal housing node of prefabricated replaceable concrete frame the first defence line support column 1 and Seismic Isolation of Isolation Layer is bolted, connected node place correspondence position pre embedded bolt.
Prefabricated replaceable concrete frame secondary defense support column 2 is prefabricated reinforced concrete column, reinforcing bar and styletable Plate Welding in post, the underframe node of prefabricated replaceable concrete frame secondary defense support column 2 lower end and Seismic Isolation of Isolation Layer is bolted, the upper frame of connected node place correspondence position pre embedded bolt, upper end and Seismic Isolation of Isolation Layer keeps certain distance.
Energy-consumption shock-absorption device 4 can be friction energy dissipation device, steel bomb plasticity energy consumer, lead extrusion damper, viscoelastic damper or viscous damper etc..
Such as Fig. 5, prefabricated replaceable concrete frame the first defence line support column 1 can recovering bearing power, replaceable concrete frame secondary defense support column 2 must support as after big shake under the effect of jack 5 owing to power consumption damages replaceable, C-shaped shell Self-resetting parallel column 3, as serious in damaged, it is possible to replace.Energy-consumption shock-absorption device 4 is as serious in damaged after big shake, it is possible to replace.
The concrete control method of the present invention is as follows:
The version that the present invention proposes is under little shake with middle shake effect, and C-shaped shell Self-resetting parallel column 3 can provide horizontal restoring force, prefabricated replaceable concrete frame the first defence line support column 1 to undertake vertical and horizontal loading together with C-shaped shell Self-resetting parallel column 3.Under big shake effect, can there is large deformation elastic displacement in C-shaped shell Self-resetting parallel column 3, and Seismic Isolation of Isolation Layer is as structural weak layer on the one hand, can absorb major part seismic energy, it is ensured that other each Rotating fields do not destroy;On the other hand, prefabricated replaceable concrete frame the first defence line support column 1 is subject to crushing a part of seismic energy that can dissipate, energy-consumption shock-absorption device 4 also can dissipate major part seismic energy, and when big shake terminates, structure is undertaken vertical load by prefabricated replaceable concrete frame secondary defense support column 2.There is elastic buckling due to " tape measure effect " in C-shaped shell 31, after off-load, C-shaped shell 31 can revert to original state, and recovers original bearing capacity when reaching critical load.Therefore, after big shake terminates, Seismic Isolation of Isolation Layer reset is carried out together with C-shaped shell Self-resetting parallel column 3 by hydraulic jack 5, replace prefabricated replaceable concrete frame the first defence line, secondary defense support column and the energy-consumption shock-absorption device 4 that have damaged, structure restores to the original state, and reaches the target of " big shake also can be repaiied ".So-called " tape measure effect " is exactly High performance carbon structural steels, it is compression molded into the C shape shell shape being similar to ribbon, if controlling the ratio (this scope needs to be recorded by test) within the specific limits of shell radius of curvature R and thickness t according to selected steel, after this shell structure occurs large deformation folding under Buckling Loads effect, not generating material surrender, and only there is elastic deformation;After yield load unloads, the deformation performance of structure resilient.
Visible, compared with prior art, after the shake that the present invention is formed, runback Interlayer seismic isolation/base isolation structure system is overturning traditional xoncrete structure building structure, the design concept of " no damage in small earthquake; middle shake can be repaiied, big shake also can be repaiied " can be realized, there is security performance height simultaneously, the plurality of advantages such as environmental pollution is little, and construction costs is low.
