Seismic Performance Test And Nonlinear Simulation Analysis Of Common Brick Masonry Wall

Masonry structure is an ancient form of building structure, it has a longhistory in our country. Previous damage shows that due to the brittle nature ofthe masonry, masonry structures badly damaged in the earthquake. Given themasonry structure is still a major form of structure in China quite a long time inthe future, seismic research of masonry structures is very important. In this paper,a font masonry wall between window with structural columns and horizontalreinforcement is tested under horizontally low cyclic loading and its model isestablished with ABAQUS finite element software. Comparing their seismicperformance, such as failure modes, carrying capacity and energy dissipationcapacity. And on this basis, simulate Models to analyze the factors affecting thebearing capacity of masonry walls. The content of the research is based onShanxi science and technology key project20110313026-3and NSFC50978177.Firstly, elaborate the development of masonry structures, the damagecharacteristics and Situation of masonry structures seismic research, the researchcontents and purpose of this paper are proposed. Brief the test specimenⅡ-TB2’s design, production processes, equipment installation and test loadsystem. Describe the crack development and the destruction process ofspecimens, and the specimen’s seismic performance, such as skeleton curves,hysteresis curves, displacement angle, ductility and energy dissipation capacityare comparatively Calculated and analyzed.Moreover, select ABAQUS finite element software to make the study ofmasonry materials and concrete materials, including their constitutive relations and plastic damage models. Establish the overall model according to the size ofthe specimen and load the analog wall to compare the simulation results and theexperimental results of seismic performance indicators. The results verify thereasonable of modeling and the accuracy and applicability of ABAQUSsimulation masonry structures.Again, based on the simulation and verification design eight walls toresearch the influence of nonlinear properties and lateral resistance capacity ofmasonry walls on horizontal bars, structural columns, vertical stress, load heightand aspect ratio. Analog wall’s stress cloud of failure process, bearing capacityskeleton curve and the displacement ductility are analyzed.Finally, design four masonry structure models, through the analysis ofmasonry structures’ stress cloud and displacement between the structural layerunder simulated earthquake, comparative study of structural columns, openingsrate and structural height influence on the seismic performance of masonrystructures.
