为研究一种新型节能墙体——现场发泡夹心墙的平面内变形性能,制作了13片现场发泡夹心墙和1片实心墙,进行了平面内的抗震性能试验。得到了墙体滞回曲线、骨架曲线、内叶墙不同高度位移时程曲线、延性系数、能量耗散系数和刚度退化曲线等,分析了轴压比、拉接件的构造参数与布局、保温层厚度等参数变化对现场发泡夹心墙的破坏特征、破坏机制、稳定性能、延性性能、耗能能力、刚度退化等影响。研究结果表明构造柱、拉接件和钢筋混凝土梁挑耳有效改善了墙体变形能力和整体性能,夹心墙具有较好的变形性能。
In order to study the in-plane deformability of a new type of energy-saving wall-field foaming sandwich wall, 13 on-site foaming sandwich walls and 1 solid wall were made and the in-plane seismic performance tests were carried out. The curves of hysteresis curve, skeleton curve, different height displacement time-history curve, ductility coefficient, energy dissipation coefficient and stiffness degradation curve of the wall were obtained. The axial compression ratio, structural parameters and layout of the pull- Layer thickness and other parameters on the on-site foam sandwich wall failure characteristics, failure mechanism, stability, ductility, energy dissipation capacity, stiffness degradation and so on. The results show that the structural columns, pull-in pieces and reinforced concrete beam picks effectively improve the deformation capacity and overall performance of the wall, and the sandwich wall has better deformation performance.
