摘要
ABAQUS作为大型非线性有限元分析软件被广泛应用于土木工程结构计算,其中混凝土损伤塑性模型是公认的在反复荷载作用下对混凝土非弹性行为模拟最为有效的模型,并被广泛地应用于高层建筑结构的时程计算分析中。但关于ABAQUS混凝土损伤塑性模型中的损伤因子的取值一直没有确定的方法。通过对比几种确定损伤因子的方法及适用条件,提出了混凝土损伤因子的取值建议。
The concrete damage plasticity model is acknowledged as an effective model to simulate the concrete inelastic behavior under cyclic loading in the ABAQUS.Therefore,it is a widely used multi-purpose FEM analysis software in civil engineering.The model is also widely used in elasto-plastic time-history analysis in high-rise building design.However,there is no reasonable way to define the damage parameter in the concrete damage plasticity model so far.This paper compared several methods to define the damage parameter and their working conditions by literature review.It provides a recommendation on how to define the damage parameter in ABAQUS.
