Abstract
To explore the optimization seismic design of frame-multi-ribbed composite wall structure, firstly the finite element model of a six story frame-multi-ribbed composite wall structure is established based on the software of SAP2000. Secondly the critical design parameters of multi story frame-multi-ribbed composite wall structure under seismic action are analysised using finite element analysis software. Finally the seismic response of the structure under different rib combinations and the optimal arrangement rule of the structure are studied. The results reveals that the lateral stiffness of the structure cannot be effectively improved by increasing the number of rib grids of the multi ribbed composite wall. The results can provide a theoretical basis for the design of the multi story frame-multi-ribbed composite wall structure in the medium and high earthquake intensity area.
