摘要本研究提出的结果，在平面内进行循环试验的无筋砖砌体墙采用喷射混凝土加固。对三个足尺试件进行了试验研究。其中一个试件作为参考，其他试件采用两种不同的加固策略，分别加固一侧和两侧的边界。根据结果，加强URM墙一侧的墙边界，结果不太令人满意。另一方面，所提出的加强两侧墙边界的技术是有效的，极大地改善了加强墙的性能。
ABSTRACT This study presents the results of in-plane cyclic tests performed on unreinforced brick masonry walls retrofitted using shotcrete. The experimental study was carried out on three full-scale specimens. One specimen was tested as reference and others were strengthened to the boundaries on one and both sides with two different retrofitting strategies. According to the results, strengthening the wall boundaries on one side of the URM wall resulted less satisfactory. On the other hand, the proposed technique in strengthening the wall boundaries on both sides was effective and extremely improved the behavior of strengthened walls.
