Non-linear analysis of new concrete composite frames construction model

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.
