Improvement in Seismic Performance of Masonry Walls with Openings in Developing Countries

有孔洞的约束砖墙与无孔洞的墙体以及无孔洞周围没有额外钢筋混凝土构件的墙体相比，可以发展出更高的横向承载能力。这表明，设置额外的钢筋混凝土构件将是一种实用的发展中国家洞口加固方法。在2009年西爪哇地震影响的一些地区可以看到，20%的封闭砖混房屋完全倒塌。

The confined masonry walls with openings accompanied by the extra RC elements could develop higher lateral load carrying capacity than the walls without any openings as well as the walls without any extra RC elements around the opening. This indicates that the arrangement of extra RC elements is to be a practical reinforcing method for the openings in the developing countries. And it could be seen in some of the areas affected by West Java earthquake in 2009 that 20% of the confined masonry houses collapse totally.
