Research for Improving Seismic Performance of Brick Masonry Walls

点击翻译按钮获取中文摘要

To improve seismic performance of the existing houses in developing countries, an investigation to propose a seismic retrofit method for masonry walls was carried out. Results are summarized as follows. Lateral load carrying capacities of the partially grouted and the unreinforced masonry walls could be enhanced remarkably by reinforced polymer cement mortar(PCM) overlay. Experimental shear capacity of the partially grouted masonry wall after retrofit could be predicted by summation of the theoretical strengths of masonry wall and PCM overlay. However, the summation of theoretical strengths exceeds experimental shear capacity of the unreinforced masonry wall after retrofit.
