| 摘 要： | 采用ANSYS软件中非线性分析常用单元:SOLID65、LINK8及COMB IN39,分别模拟混凝土、钢筋以及钢筋与混凝土的黏结滑移,建立分离式模型模拟四层两跨钢筋混凝土框架的荷载位移曲线,通过与试验结果的比较,验证模型的正确性。然后根据ANSYS中建立分离式有限元模型模拟不同轴压比、不同混凝土强度及不同配筋情况下框架的荷载位移曲线,分析以上因素对水平承载力的影响。

| Abstract: | The paper simulated Load-displacement curves of four-story and two-bay reinforced concrete frame under laterally monotonic load by ANSYS software using common elements of non-linear analysis,such as SOLID65,LINK8 and COMBIN39 for simulating concrete,reinforcing steel bar and bond-slip between the reinforcement and concrete respectively.The numerical modeling results were compared with the experimental results in order to confirm the feasibility of discrete model.Based on the discrete non-linear finite element model in the software,the load-displacement curves of reinforced concrete frame with different axial compression rations,different concrete strength and different reinforcement ratio were obtained and then analyzed the influence of on the horizontal carrying capacity. |
