非承重页岩空心砖墙体变形性能试验研究

Experimental study on the transformative behavior of non-bearing shale cavity brick masonry walls

通过对一眠一斗、一顺一丁、两顺一丁3种砌筑形式配置水平钢筋与未配置水平钢筋的空心砖墙体的低周往复荷载试验,分析该种墙体的破坏形态、抗震性能及变形性能。分析表明,该墙体具有较好的整体性。配置水平钢筋不仅可以提高墙体的承载能力,而且可以大大提高墙体的抗震能力和变形性能。

Based on the low cyclic reversed lateral loading tests of cavity brick masonry walls having three different masonry styles and installed horizontal reinforced bars in the walls,the destroyed configuration, seismic behavior and the transformative behavior of cavity brick masonry walls were studied. The analytic results reveal that the walls have good capability as a complete entity. The setting of lateral reinforced bars can not only improve the bearing capacity of the wall but also greatly improve the seismic behavior and tile transfonnative behavior of the wall.
