摘要
本文以装配式建筑中的一种新型预制混凝土叠合梁复合内填充墙体为研究对象,基于混凝土塑性损伤本构模型,采用有限元分析软件ABAQUS分别建立包括和不包括叠合梁复合内墙的局部结构模型、标准楼层模型和整体结构模型,分析了叠合梁复合内墙对结构抗侧刚度的影响以及在罕遇地震下的耗能能力。分析结果表明,叠合梁复合内墙可显著增加局部结构的刚度,但由于这种墙体在建筑户型布置中数量较少,其对标准楼层的刚度影响较小。叠合梁复合内墙通过自身塑性耗能和损伤耗能较大程度地提高了结构整体抗罕遇地震性能。
This paper study on a new precast concrete composite beam with interior infilled wall(PCB-IW)in assembled building.Based on concrete damaged plasticity model,the structural models which contain local structure model,standard floor structure model and total structure model were built respectively by finite element analysis software ABAQUS.Two kinds of conditions were considered in these finite element models which contain or not contain PCB-IW.The influence on structural lateral stiffness and energy consumption capacity of PCB-IW under rarely occurred earthquake were analyzed.The results show that PCB-IW can increase structural stiffness significantly in local structure,but such influence are less in standard floor structure due to few PCB-IW in the house type.PCB-IW can increase the seismic performance of total structure under rarely occurred earthquake significantly by consuming its own structural plastic energy and damage energy.
