SEISMIC RESPONSE ANALYSIS OF FRAME-SUPPORTED MULTI-RIBBED COMPOSITE WALL STRUCTURE

摘要

Multi-ribbed composite wall structure is a new type of structure which has certain advantages in seismic performance and energy dissipation. During the former research, a large number of significant achievements have been made. However, as a new building structure, there are still some problems for further study, especially for the frame-supported multi-ribbed composite wall structure with large space at the bottom, where there is a transfer story. In this paper, based on the former experiment, the simplified calculation model of frame-supported multi-ribbed composite wall structure is presented. In order to study the seismic performance of the structure, the seismic response analysis is developed with the application of time history analysis, and the distributing rules of maximum displacement and story drift are obtained. It draws the conclusion that the maximum drift angle at the transfer story is dramatically increased, and the stiffness ratio in frame-supported multi-ribbed composite wall should be seriously restricted.
