SEISMIC PERFORMANCE-BASED ANALYSIS OF CONFINED MASONRY STRUCTURES
Confined masonry buildings (CMBs) have been widely used in China. The field survey conducted during the recent great Wenchuan Earthquake had been proved that the CMBs well designed and constructed performed well even in severely affected areas. However, the performance-based design for the CMBs has been few reported. In this paper based on the previous work conducted by the author a four-linear skeleton curve with negative stiffness for the confined masonry walls along with the parameters characterizing the different performance levels is developed. Nonlinear time history analysis (NTHA) and nonlinear static analysis -- pushover analysis (POA) for four typical 5- to 7-story confined concrete/ brick masonry buildings are performed. From comparisons of the numerical results some conclusions are made, they could be helpful for further investigation and promotion of a wider application of the CMBs.
