考虑梁柱节点黏结-滑移模型的混凝土框架滞回性能研究
|
摘要
基于有限元软件OpenSEES中已有的梁柱宏观柔性节点单元和梁柱纵筋黏结滑移模型,对国内研究者已经完成的钢筋混凝土框架以及型钢混凝土框架水平低周往复荷载试验得到的滞回曲线、位移延性、滞回面积以及耗能能力等滞回性能进行有限元模拟分析,并与试验结果进行比对。根据有限元模拟结果建立基于OpenSEES软件的钢筋混凝土框架和型钢混凝土框架考虑梁柱宏观柔性节点的计算模型,为钢筋混凝土框架和型钢混凝土框架的设计计算提供一条有效途径。
Utilizing the beam-column joints element and bond-slip model of OpenSEES, the author analyzed the hysteresis performance obtained from horizontal low cycle reciprocating load test of reinforced concrete frame and steel reinforced concrete frame that have been completed by domestic researchers, including the hysteresis curve, displacement ductility, hysteresis area and energy dissipation capacity, and compared simulation results with test results. Based on the simulation results, the author established the calculation model of concrete frame and steel reinforced concrete combine frame with macroscopic mechanical model, which provides a convenient way for the design and calculation of concrete frame and steel reinforced concrete combine frame.
