摘要
基于一榀1/3缩尺新型U形钢筋混凝土组合梁-钢筋砼柱组合框架结构模型在低周反复荷载下的试验成果,采用ANSYS参数化程序设计语言(APDL)编制了命令流,对模型框架在低周反复荷载作用下的抗震性能进行了非线性有限元分析(FEM).FEM考虑了钢筋和混凝土间的相互作用,以及结构钢和混凝土间的相互作用,模拟得到了单调加载及反复加载下模型结构的荷载-变形关系曲线,验证了所建模型分析组合框架结构全过程分析方法的可行性,以及所编制的APDL命令流程序对组合框架结构抗震计算的有效性,为组合框架结构抗震设计提供了实用的计算软件.
Based on a reduced scale 1/3 combine of frame construction model with new U reinforced concrete composite beam-reinforced concrete column under experiment of low weekly repeatedly load,the ANSYS programming language(APDL) is used to establish the order classes,and to carry on the non-linear finite element analysis(FEM) to the frame model under low weekly repeatedly load′s earthquake behavior.Analysis of the specimen was conducted after testing the behavior of the specimen.FEM analysis took into consideration the interaction between the reinforcement and concrete.The simulation obtains the model structure′s load-distortion relation curves under the conditions of monotonous load increase and repeatedly load increase,confirms the feasibility of the new model,and establishes the APDL order flows′ validity to the combined frame construction earthquake computation.It has provided practical computation software for the design of the composite frame construction′s earthquake resistance.
