中文摘要：

本文通过对2片开窗洞砌体墙试件（素墙、喷射玻璃纤维加固）进行水平低周往复加载试验，研究开窗洞砌体墙加固前后的抗震性能。试验结果表明，采用喷射玻璃纤维聚合物（SGFRP）加固后的砌体墙受力变形性能较加固前有明显改善；其开裂荷载、极限荷载、极限位移和延性等抗震性能均显著提高。因而，SGFRP加固开窗洞砌体墙片是一种可行有效的抗震加固方法。

英文摘要：

Two specimens of masonry walls with window-openings （one was plain, the other was strengthened by Sprayed Glass Fiber-reinforced Polymer Composites （SGFRP）） were tested under low-frequency cyclic lateral loading to study the walls＇ anti-seismic capacity. It was found that the properties of stress and deformation of the strengthened wall were better than those of the plain wall. Besides, the masonry wall had bigger crazing loading, ultimate loading, ultimate displacement and ductility after being strengthened. Therefore, SGFRP- strengthening-method is one of the effective methods to strengthen masonry walls with window-openings.
