SEISMIC PERFORMANCE ASSESSMENT OF MULTISTORY BUILDINGS WITH NON-STRUCTURAL HOLLOW CLAY TILE INFILLS

In recent years, walls made by Hollow Clay Tiles (HCT), have been used as a common partitions in Iran and other countries. These partitions are generally thought as non-structural elements and hence not considered in analysis and design of buildings; this is due to the lack of information about the seismic performance of partitions. In this study, based on experimental tests, a new analytical backbone curves are proposed to simulate the performance of HCT partitions. Partitions considered in this study have two types of overlays (plaster + browning plaster and cement), R.C. frames are in 3 and 6 stories and OpenSees software is used for non-linear modelling.The effect of presence of this type of partitions in seismic performance of R.C. frames is investigated by modal and nonlinear push-over analysis. It has been observed that the presence of the wall makes a significant reduction in fundamental period of frames while the changes in mode shapes are not considerable. On the other hand, the deformation capacity of the frames decreases.
