Research On Bearing Performance Analysis And Calculating Model Of Concrete Frames–fiber Plasterboard

Glass fiber reinforced gypsum wall is new building material and hasmany advantages than brick, but problems on engineering application andmechanical analysis need be solved at present. Based on the domestic andabroad researches and by a series of push-out test results, the relationsbetween the bond stresses and slip, three-dimension model were analyzed.At the end,a simple model was analyzed by this paper.First, the push-out test specimens were numerically simulated. Inorder to take the ineraction between the fiber plasterboard and theconcrete core into account, combination39elements were used tosimulate the three directional interactions. The simulation results werecompared with the experimental results.Second, based on the model experiment on seismic behavior, acommand stream is edited and the nonlinear finite element analysis of thestructure on the seismic behavior and model walls underhorizontal-low-cyclic loading with constant vertical loading is completed.The calculated results are much coincided with the tested results.Finally, a simple mechanical model was analyzed. ACol-Be&Combin system was carried out. Through the analysis of theinternal force of spring, a series of rules was founded. The results of threedimensions model under different lateral loads were compared with thatof FEM analysis to prove the validity of macro model.
