Numerical Simulation of Wood Diaphragm in Concrete and Timber Hybrid Structure

Abstract:

Based on Sap2000,two different concrete-timber hybrid structural models:detailed timber floor model and simplified timber floor model were established and used to do numerical simulation for a test of a one-storey hybrid structure under lateral load.At last,simplified floor model and rigid floor model were used to build up two 6-storey structural models and were analyzed under seismic load.Results show that,both of detailed timber floor model and simplified floor model can simulate well the hybrid structure test; in order to simplify the analysis of hybrid structure,the simplified floor model can take place of the detailed floor model; according to the seismic analysis results of simplified floor model of 6-storey building,the mid-frame takes more lateral load than side-frame;the time history seismic analysis results show that,the time-displacement curves on the top of simplified wood diaphragm model and rigid floor model are very close.
