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 'quake-proof heat-preservation sound-insulation integrated wall' (Chinese application No. 201710552568.8) filed in 6.6.2017 by Lizhong, Sun Fei and Jinhuajian.
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:
the first problem is that: under the condition of small earthquake, the corrugated steel plate wall improves the rigidity of the structure and simultaneously improves the earthquake action of the input structure, and when the characteristic period of the field is approached, the reduction of the displacement between the floors of the structure caused by the structural rigidity improvement of the corrugated steel plate wall is probably smaller than the increase of the displacement between the floors of the structure caused by the increase of the earthquake action due to the structural rigidity improvement. 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 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 figure 1 are always subjected to the maximum vertical force. The problems that result from this are: the earthquake action is in a reciprocating two-direction circulation mode, under the action of a large earthquake, the outer side flange (2-2) of the corrugated steel plate wall edge member is also in reciprocating 'tension' and 'compression' and has the largest stress amplitude, so that the outer side flange (2-2) can be subjected to fatigue failure, the corrugated steel plate can not normally work, and the wide popularization of the corrugated steel plate is influenced.
