摘要:
采用ANSYS分析软件,对顶端刚接和脱开的2种填充墙进行平面外受力变形性能的非线性数值模拟分析,考察了均布荷载和层间位移作用下,墙体开裂过程中的应力变化和破坏模式,验证了顶端刚接墙体在开裂后期存在明显的拱作用。结果表明:顶端刚接的填充墙在均布荷载作用下宜按三铰拱模型考虑,在层间位移作用下宜按两铰拱考虑; 而顶端脱开、钢筋拉结的填充墙在均布荷载和层间位移作用下均可按顶端铰支、底端固接的模型考虑。
Abstract:
Two kinds of infill walls were numerically simulated and analyzed in nonlinear way by using ANSYS analysis software, one of which was rigidly connected to top beam; the other was connected to beam with reinforcement. Under uniformly distributed load and story displacement, the infill wall cracked. In the process of cracking, the stress changing and failure modes of walls were inspected. The arch effect of rigidly connected wall was obviously represented in late cracking period. Results show that the infill wall rigidly connected on top can be considered with three hinge arch model under uniformly distributed load, and can be considered with two hinge model under story displacement. The wall separated from top beam and connected by reinforcement can be simplified with the model of hinge joint on the top and consolidation on the bottom under uniformly distributed load and story displacement.
