Abstract:
The assembled cross-ribbed steel plate shear wall structure was proposed, the finite element analysis method was used to establish the finite element model of shear wall test of longitudinal and transverse multi-ribbed steel plate, and the validity and reliability of the modeling method was verified. The finite element model of cross-ribbed steel plate shear wall was established, the embedded steel plate height thickness ratio, multi-ribbed steel plate grid size were selected for variable parameters analysis, and the hysteretic curve, viscous damping coefficient, skeleton curve and stiffness degradation of each series of specimens were compared. The influence of geometric parameters of embedded steel plate wall on the hysteretic performance of cross-ribbed steel plate shear wall was analyzed, and the reasonable range of two parameters was given. The results show that when the height thickness ratio of the embedded steel plate λ≥ 500, the energy dissipation capacity, lateral bearing capacity and ductility of the test specimen increase significantly with the decrease of the height thickness ratio of the embedded steel plate. When λ<500, the above performance improvement is not obvious, and the recommended value of the embedded steel plate height thickness ratio λ is 500-600. The grid size of cross ribs has a significant effect on the hysteretic performance of specimens. The performance of the specimen increases with the decrease of the grid size of cross rib, and the increasing range is positively related to the decreasing range of the grid size. It is suggested that the number of cross-ribbed grid ribs should be less than or equal to 5×5.
