［摘要］通过对4片有上部结构的带构造柱开洞组合墙在上部竖向荷载和楼盖梁端集中荷载下出平面偏心受压性能试验，了解了开洞对柱、圈梁与砌体墙共同工作性能的影响，揭示了开洞对截面应力沿墙体水平和竖向的传递与分布规律以及对裂缝出现与发展、构件变形与破坏机理的影响，找出了组合墙出平面偏心受压性能的影响因素与规律。为补充和完善现行砌体结构规范以及组合墙出平面偏心受压的基本理论与计算方法提供了试验依据。

Abstract:Based on the tests of 4 pieces of composite masonry walls with holes which were subjected to vertical load and concentrated loading out-of-plane of the upper floor beam, the influences of holes on the coordination of columns, ring beams and masonry walls under upper floors and concentrated loading out-of-plane were discussed. The transfer and distribution of section stresses in the horizontal and vertical direction of the walls affected by holes, emergence and development of cracks, deformation and failure mechanism of members were revealed. The reasons and rules influencing the behaviors of the composite masonry walls were discovered, which will provide experimental basis for the basic theory and calculation methods of composite masonry walls under out-of-plane and eccentrical compression, in order to fill the blank of current code of masonry structures in those aspects.

Keywords:structural column; composit masonry walls; hole; upper structure; loads; out-of-plane; eccentric compression
