摘要:
利用有限元分析软件ABAQUS建立5榀不同内填材料生态复合墙体的数值模型,对其进行非线性损伤分析,并与试验结果进行对比,研究5榀生态复合墙体的损伤场的分布状况和塑性损伤行为,分析墙体典型部位区域的损伤演化全过程,提出生态复合墙体基于性能的分灾设计方法的理念。结果表明:生态复合墙体的损伤区域主要集中在中间层砌块、肋梁和肋柱交界处以及外框柱脚和柱顶处;局部和整体损伤指数时程变化规律在变形累积效应下表现出非减特性;整体损伤指数为生态复合墙结构震后评估提供一定的理论依据;砌块、肋格及外框是生态复合墙结构的3道抗震防线。
Abstract:
The numerical models of the 5 ecological composite walls filled with different materials were established by finite element analysis software ABAQUS, then the nonlinear damage analysis was carried out, and the results were compared with experimental results. The damage field distribution and plastic damage behavior of 5 ecological composite wall models were studied, the damage evolution process of typical region of wall was analyzed, the idea of damagereduction design method based on the performance of ecological composite wall structure was put forward. The results show that the damaged areas of ecological composite walls are mainly concentrated in the middle layer of blocks, the junctions of ribbed beam, ribbed column and base and top of end frame;the changing laws of damage indexes of local and global are increased by the effects of accumulative deformation; global damage index provides certain theory basis for earthquake evaluation of ecological composite wall structure; block, ribbed grid and frame are three seismic fortification lines of ecological composite wall structure.
