摘要
通过有限元分析软件ABAQUS建立某12层框架结构并进行时程分析,基于混凝土损伤塑性模型,研究了该框架结构在地震作用下的结构开裂损伤发展状况,探讨了应用混凝土损伤塑性模型预测钢筋混凝土框架结构整体损伤及裂缝发展的可行性及存在的问题,为相似的框架结构的损伤破坏提供理论支持。
Based on the ABAQUS software, a 12-story frame structure is modeled with refined finite element method and the nonlinear time-his- tory analysis is carried out to study the damage and crack propagation of the frame structure subjected to seismic excitation. This paper discusses the applicability and problems to predict the overall damage and crack propagation for reinforced concrete structure by using the concrete dam- aged plasticity model, providing theoretical basis for structural design and maintenance.
