Title: Seismic Performance Analysis of Bottom-Sealed Block Composite Masonry Buildings Supported by Frame/Shear-Wall Structure with Large Spacing in the First Storey
Abstract: The paper attempts to evaluate the seismic performance of bottom-sealed block composite masonry buildings supported by frame/shearwall structure with large spacing in the first storey and discuss the possibility of using them in seismic regions with intensity 7 of Chinese intensity scale.Based on the simplified series-parallel lumped model,with separate treatment of the different earthquake resistant elements as independent analysis elements,the code-based mode decomposition response spectrum method and inelastic time-history analysis by earthquake wave records are used.Statistical response data of a trail designed 6 story building are adopted for the discussions of the seismic performance,weak stories and displacement concentration problems.Failure probability and reliability index are estimated under the theory of seismic reliability.The transient story is a little weaker than others,but no obvious weak story or displacement concentration is found,however,under severe earthquake excitations.Favorable seismic performance and appropriate reliability index are discovered for the buildings.It is feasible to build similar 6-storey buildings in seismic region with intensity 7 of Chinese intensity scale.
