Study on Seismic Behavior of Large Bay Brick Masonry Structures with Fewer Internal Longitudinal Walls

Abstract

The Wenchuan earthquake and Yushu earthquake indicated that the damage of large bay brick masonry buildings with fewer internal longitudinal walls, even no longitudinal wall in the sitting room was much heavier than the ordinary buildings. In order to study this damage phenomenon, the typical buildings were analyzed. (one is large bay building, another is ordinary building) The reserve coefficient of average shear capacity is used to evaluate the seismic capacity of the structure. The analytical results show that the safe reserve coefficient of the latter one is smaller, and easy to damage. Therefore, such building in earthquake zone should add the longitudinal wall in the sitting room to strengthen the local longitudinal stiffness.
