| 摘 要： | 基于Opensees地震工程数值模拟平台,实现了组合梁钢筋混凝土柱单层单跨平面框架结构在单调水平荷载作用下骨架曲线的有限元模拟,并与相关试验结果进行对比分析.数值模型中,混凝土采用修正的Kent-Park模型,钢材采用理想弹-塑性模型,并采用位移增量法控制加载.基于此,对影响此类框架结构P-Δ曲线的因素进行了参数分析,抗震性能良好.

| Abstract: | Finite element numerical simulation based on Opensees develops the monotonic curve of monolayer and single span plane frame with composite beam and reinforced concrete column under a lateral load.Simulation results are analyzed and compared with measured results.In the simulation,concrete material is modeled by the modified Kent-Park constitutive model while the steel is modeled by real elastic-plastic constitutive model,and the nonlinear equations are solved by the incremental displacement method.The predominant parameters that affect the mechanical behavior of this type of frame structure are analyzed.Results indicate that the frame structures have good aseismic performance. |
