摘　　要：为了提高砖墙体的抗震能力，特别是在强烈地震下的变形能力，进行了配筋砌体钢筋 端部不同形式锚固的试验研究．试验结果表明，水平配筋墙体钢筋端部锚固对墙体的变形能力有明显的提高．Ｔ字形锚固钢筋墙体的变形能力为无锚固墙体的１．３倍，直角弯钩锚固墙体的变形能力为无锚固墙体的１．１倍．配筋墙体有端部锚固时，极限承载力可提高４％～１１％．在实践施工中，可将丁字头锚固改为在墙端焊接一根通常钢筋，这样施工更易操作，约束效果更佳。In order to improve the seismic performance of brick walls, especially the deformation ability under strong earthquake, three experiments of reinforced brick walls with different anchorage form at bar ends are carried out. The results show that the deformation ability of the walls with the bar ends anchored in T-type and L-type are respectively l.3 times and 1.1 times higher than that of the wall with no anchored end measure and ultimate forces are increased by 4% ~ 11%Jn practice a steel bar can be welded at the end of the wall instead of J-type end, which is much easier to handle and the constraint effect would be more excellent.
