Description
Technical Field
The application relates to the energy dissipation and shock absorption field of the building engineering technology.
Background
The corrugated steel plate wall is a very effective energy-dissipating and shock-absorbing component, and can dissipate energy in moderate and rare earthquakes. Closest to the prior art:
the 'buckling-free waveform structure energy consumption component and the design method thereof' are applied and filed 6.6.2017 in Lizhou, Sun Fei and Jinhuajian, respectively (China application No. 201710425071. X).
The integrated wall is a seismic-resistant, thermal-insulation and sound-insulation wall (China application No. 201710552568.8) which is applied and filed in 6.6.2017 by Lizhong province, Sun Feifei and Jinhuajian provinces.
The advantages of large out-of-plane rigidity of the wave type are fully utilized, the excellent performance of the member is ensured, the economy is good, the processing is convenient, and the method has wide application prospect. However, although this kind of corrugated steel plate wall is a very effective energy dissipation and shock absorption member, its characteristic is: the elasticity is kept under small earthquake, only rigidity and bearing capacity are provided for the structure, energy dissipation is achieved through yielding under medium and large earthquake, earthquake action borne by the structure is reduced, and certain rigidity after yielding is provided. When the corrugated steel plate wall is applied, two problems still exist at present:

Coping with the problems, the elastic design requirement under the condition of small earthquake can be met by increasing the section of the main body structure in the prior art, obviously, the economic performance of the scheme is poor, and the popularization significance is not realized.
The second problem is that: the force mechanism of the corrugated steel plate wall shown in fig. 1 is as follows: under the action of earthquake, the middle corrugated steel plate (1) is mainly subjected to shearing force, the two side edge components (2) are used for balancing the overturning bending moment of the non-buckling corrugated steel plate (1) and mainly subjected to vertical axial force, and the outer side flanges (2-2) of the edge components (2) shown in the figure 1 are always subjected to the maximum vertical force. The problems that result from this are: the earthquake action is circulated in two reciprocating directions, under the action of a large earthquake, the outer side flange (2-2) of the corrugated steel plate wall edge member is also reciprocated to be pulled for a moment and pressed for a moment, and the stress amplitude is maximum, so that the outer side flange (2-2) can be subjected to fatigue damage, the corrugated steel plate can not normally work, and the wide popularization of the corrugated steel plate is influenced.
