Design And Experimental Analysis Of Brick Masonry Walls With Construction Columns

In recent years, the strong earthquakes worldwide occur more and more frequently, and population density further increases with the degree of urbanization in China to further promote the harm caused by the earthquake will become more and more serious. In this paper, the seismic performance of masonry structure wall will be studied, and this research is belonged to National Natural Science Foundation (Grant No.50978177)First of all, through the review of the specification of the masonry structure in China and its comparison with foreign norms, review the development of the masonry structure in the our country.Through the review and analysis of the pilot study of masonry structures at home and abroad in recent years,found relatively few studies of the seismic capacity of masonry structure and seismic design philosophy and methods at home and abroad.Through the Analysis and research on the cracks and failure modes of masonry shear wall at the Wenchuan earthquake, study of the seismic advantage when the masonry walls in the normal section of the bending failure. Then, a detailed description of the wall specimen construction were made to the " Avoid shear failure of high-performance seismic masonry structure " test. Specimen of the test wall construction (including prefabricated top and bottom of the beam production, the wall of the masonry, structural column, pouring, and paste the strain gauge), the basic mechanical properties of wall materials and time to load device detailed description and the specimen loading scheme design. The construction process of the trial in strict accordance with our existing norms. Fully prepared to conduct the pilot research project.In order to study with the flexural capacity of structural column and reinforced masonry shear wall at the level of constraint. The numerical analysis model and the finite element analysis model were established for the masonry wall. Influencing factors in the analysis of masonry shear wall bearing capacity and failure modes on the basis of previous experimental studies. Study on the factors of masonry flexural and shear strength of shear wal. On the basis of experimental studies and theoretical analysis, the formula were established of the flexural capacity level constraint reinforced masonry shear wall. The numerical calculation of the flexural and shear capacity of masonry shear wall. Finite element model for masonry shear wall at the constant pressure flexural and shear capacity and failure modes analysis. Stress and strain analysis on the level of constraint reinforcement and the central structural column reinforcement. Study the role of the shear wall at the bearing capacity. And finite element analysis results and numerical analysis of the results were compared.
