水平反复荷载作用下双层空心墙体抗震性能的试验研究

Test and Analysis of Aseismic Behavior of Brick-cavity Wall Under Lateral Cyclic Loading

本文通过十四片具有不同构造措施的双层空心墙体和两片实心砖墙体试件的周期反复加载试验,研究了双层空心墙体在水平周期反复荷载作用下的基本性能,分析和比较了具有不同构造措施的双层空心墙体的破坏机理,滞回性能、廷性等.分析了双层空心墙体的开裂荷载、极限荷载、变形等,并且提出了有关双层空心墙体的设计建议.

Under Vertical and lateral cyclic loading,fourteen brick cavity wall and two normal brick wall specimens have been tested. In specimen design,different connections and cross section of reinforced concrete column in the cavity wall were taken into account. The failure mechamism ,hys-teretic characteristics and ductility of the wall have been discussed and compared. Experimental results showed that the cavity wall was reliable in the seismic districts. However,Some improvements have to be taken in the wall design,and some suggestions were given.
