| 摘要: |
| 为建立基于受力状态的剪切破坏配筋砌体剪力墙的失效判定准则，以低周往复荷载作用下发生剪切破坏的290 mm厚配筋砌块剪力墙试验数据为基础，推导结构受力状态与外荷载之间的关系并给出相应的计算公式，通过分析构件在不同受力阶段的破坏机理，引入构件基于受力状态承载能力包络线的概念及相关计算方法.结合承载能力包络线与结构受力状态-荷载关系曲线，建立构件基于受力状态的失效判定准则，从而确定其开裂、失效和极限荷载.与试验的对比分析表明，本文建立的准则能够准确预测剪切破坏配筋砌块剪力墙的开裂、失效和极限荷载.该准则为结构分析和墙体失效荷载的确定提供了一种全新的途径，并拓展了试验数据的应用途径.

| Abstract: |
| Test data of reinforced masonry shear walls failed in shear with thickness of 290 mm under cyclic load were employed to establish a criterion for judging the failure loads of reinforced masonry shear walls based on stress state. The relationship between the structural stress state and external load was deduced, and the concept of bearing capacity envelop was introduced based on the failure mechanics of the wall at different stages. By combining the stress state-load relationship with the bearing capacity envelop, a stress state-based criterion was established to judge the crack, failure and ultimate loads of shear walls, which was validated through the comparison between the calculated results and the test results. The proposed criterion provides a new way for structural analysis and extents the application of test data.
