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。
Through the test of 4 eccentric structures with columnar structure with columnar structure, the eccentric load behavior of the column under the vertical load at the upper part and the concentrated load at the end of the beam, Work performance. The influence of the opening stress on the horizontal and vertical stress distribution along the wall, the appearance and development of the crack, the deformation and failure mechanism of the member were revealed, and the out-of-plane eccentric compression performance of the composite wall Influential factors and laws. The experimental basis is provided for supplementing and perfecting the existing masonry structure norms and the basic theory and calculation method of eccentricity and compression of combined wall.
