基于OpenSees的RC柱拟静力数值分析模型
Numerical Analysis Model for Pseudo-static RC Columns Based on OpenSees
摘要
Abstract
The reinforced concrete column in equal displacement loading quasi-static test was analyzed by OpenSees. Considering the effects of different steel and concrete constitutive selection and match, fiber division, element division, integration points on numerical simulation, a reasonable and effective numerical model was made. The results indicate that:in OpenSees, the results vary greatly when selecting different steel and concrete constitutive models to simulate. Matching different steel and concrete constitutive models also have a greate effect on numerical simulation results; for steel constitutive, Steel02 and ReinforcingSteel simulation results are better than Steel01, and they matches different concrete constitutive;for concrete constitutive, Concrete01 simulates best;the form of fiber cross-sectional division has a great impact on the simulation results. When the fiber is divided m=1 parallel to the direction of force, n=10 perpendicular to the direction of force,the result can meet the precision requirement; the number of elements has some influence on the simulation results, 5 elements can achieve the precision;integration points have little effect on the simulation results, when a element has 4 integration points, the calculation precision of the model is already high.关键词
