【摘要】：为研究中间保温层复合墙体结构的抗震性能,通过对中间设置保温层复合墙体和普通混凝土墙体(与复合墙体的混凝土厚度和配筋率相同)在竖向小偏压荷载作用下的低周反复荷载对比试验,研究了两类墙体的破坏过程、破坏形态、承载力、滞回特性及复合墙体两侧混凝土协同工作的能力。分析对比了试件的破坏形态、滞回曲线、骨架曲线、承载力、刚度退化、位移延性、耗能能力及钢筋应变。研究结果表明:中间设置保温层复合墙体与普通混凝土墙体具有相似的破坏形态;中间设置保温层复合墙体比普通混凝土墙体具有更高的承载力及更好的抗震能力;中间设置保温层复合墙体两侧混凝土具有良好的协同工作的能力。
[Abstract]:In order to study the seismic behavior of interlayer composite wall structure,In this paper, the failure process of two kinds of walls is studied by comparing the low-cycle repeated load under the action of vertical small eccentric load between the composite wall with insulation layer and the ordinary concrete wall with the same concrete thickness and reinforcement ratio as the composite wall.Failure form, bearing capacity, hysteretic characteristics and the ability of concrete on both sides of composite wall to work together.The failure pattern, hysteretic curve, skeleton curve, bearing capacity, stiffness degradation, displacement ductility, energy dissipation capacity and strain of steel bar were analyzed and compared.The results show that the composite wall with insulation layer has similar failure form to the ordinary concrete wall, and the composite wall with insulation layer has higher bearing capacity and better seismic resistance than ordinary concrete wall.The concrete on both sides of the composite wall with insulation layer in the middle has the ability to work together well.
