论文介绍6片不同高宽比的水泥聚苯模壳格构式混凝土墙体在轴压力和水平往复侧推力作用下的试验,分析这种墙体的抗侧强度、刚度和延性等力学性能.试验表明,高宽比大于1的墙体破坏时表现为墙体跟部的单一水平裂缝,其他部位完好;高宽比3∶4的墙体破坏时存在多条通过格构梁柱的斜向裂缝,墙体裂缝分布密集,变形能力好.
In this paper, six kinds of concrete with different aspect ratios of cement-polystyrene concrete shell wall under axial pressure and horizontal reciprocating thrust are tested. The mechanical properties such as lateral strength, stiffness and ductility of the wall are analyzed. Experiments show that when the aspect ratio is greater than 1, the wall shows a single horizontal crack in the heel of the wall with other parts in good condition. When the wall with the aspect ratio of 3: 4 destroys, there are multiple inclined lines passing through the lattice beam Cracks, wall cracks distributed intensive, good deformation capacity.
