Finite Element Analysis Of Masonry Wall’s Experimental On Seismic Test For Masonry Piers With Structural Columns

This paper focuses on the wall between the windows with a structuralcolumn seismic finite element simulation analysis, focusing on the failure modeof the wall, deformation capacity, energy dissipation capacity, carrying capacityand other characteristics were analyzed.Firstly, show previous damage, building damage masonry structures moreserious seismic performance to be improved. This article first developmentstatus masonry structure, Present Situation failure modes are outlined, wediscussed how to improve the seismic performance of masonry and thedevelopment direction of masonry structure proposed content and purpose ofthis article. In this paper, this quasi-static test were introduced, including thebathroom with a window wall structure column specimen design and installation,and the load on the loading device of the present experiment also made a briefintroduction. The conclusion that the results of this test, the wall shear failure,seismic performance to be improved.In this paper, finite element software ABAQUS a brief introduction,introduces the establishment of model selection and calculation principlesoftware and finite element model unit and determine model parameters andcomparative analysis of the model last. By using ABAQUS finite element analysis software the following conclusions:(1) The optimal loading height window wall between test finite elementmodel is2200mm.(2) Whether the comparison between the two windows through structuralcolumn wall model found structural column can significantly improve theseismic performance of the wall between the windows, but also can improve theductility of the wall.(3) The best vertical window wall between test stress finite element modelis0.3-0.5MPa.(4) Test wall and from cyclic loading model to analyze the stress cloud wallshear failure can be determined. By comparing the simulated and experimentalobtained hysteresis curves and skeleton curves, I-TS2and Q-1curve is closer tothe high degree of similarity.(5) Based on the presence or absence of structural column constraintsmasonry structures and masonry structures were different mortar strengthcomparison elastoplastic time history analysis, structural column and come witha high strength mortar masonry structure seismic performance than low nostructural column and mortar strength of masonry structures.
