Background
One of the hotspots of the present engineering seismic research: how to reduce the irrecoverable damage of main bearing members and non-structural members of a building structure after an earthquake so that the structure can be quickly repaired and normally used after the earthquake. The energy dissipation component is arranged in the structure, so that input energy of an earthquake can be effectively dissipated, and deformation of the structure is mainly concentrated in the energy dissipation component.
Both the flat steel plate shear wall and the corrugated steel plate shear wall are structural members with better seismic performance, and research and application in recent years are more and more deep and wide. The non-stiffened flat steel plate shear wall is easy to buckle under the action of horizontal shear, and the fatigue resistance of the flat steel plate under the action of reciprocating load is insufficient. The corrugated steel plate shear wall is formed by cold rolling a flat steel plate, is an improvement on the traditional flat steel plate shear wall, improves the out-of-plane buckling resistance of the corrugated steel plate due to the corrugated bending, and has slightly different ultimate bearing capacity compared with the flat steel plate.
By adopting the measure of covering flat steel plates on the two sides of the trapezoidal corrugated steel plate, closed sections can be formed at the positions of the wave troughs and the wave crests of the trapezoidal corrugated steel plate respectively, so that the material utilization efficiency can be improved, and the bearing capacity can be improved; meanwhile, the trapezoidal corrugated steel plate is equivalent to that stiffening ribs are added to the flat steel plates on the two sides, so that the out-of-plane buckling resistance of the flat steel plates can be enhanced to a certain degree; however, the steel plate in the shear wall is in a complex stress state, and the failure mode of the steel plate is difficult to control, so that the yield load and the yield displacement of the steel plate cannot be accurately judged, and the design of parameter yield force and controllable yield displacement is inconvenient to realize. Meanwhile, for the corrugated steel plate with small thickness, the corrugated boundary can not be connected with the edge beam column through a welding seam, and only can be partially connected with the edge frame at the wave trough position through bolts, so that the mode of swinging deformation and torsional deformation damage is easy to occur, and the function of the corrugated steel plate can not be fully exerted.
When the corrugated steel plate is used as a partition wall of the module unit, the corrugated steel plate is subjected to side rigidity resistance and ultimate bearing capacity because a door and window opening needs to be arranged and a whole corrugated steel plate needs to be subjected to hole forming treatment; the combined corrugated steel plate shear wall with two connected sides is beneficial to arrangement of door and window openings, can provide strong lateral resistance for the module units, and meanwhile, the heat insulation plate can be placed in a closed area formed between the corrugated steel plate and the flat steel plate.
