Analysis of Brick Walls Failure Modes under Earthquake Effect
Brick wall has large lateral sidesway stiffness and shear failure often occurs under horizontal earthquake effect, but the scourge surveys indicate that flexural failure can also occurs sometimes.Given that there are still few researches about masonrys failure modes in China, Finite Element Models of non-reinforced brick masonry with different Depth-width Ratios and reinforced brick masonry whose Depth-width Ratio is 1.444 are established with the help of MSC.MARC to analyze its failure mode under horizontal action.The researching results indicate that: The larger the Depth-width Ratio of non-reinforced brick masonry is, the more flexural components it has and the better its ductility is; the smaller its Depth-width Ratio is, the larger the D-value of Bottom Shear and Ultimate Shear Bearing Capacity according to formulas from code before damage, and thereby the more easily the shear failure takes place; however, the ductility of brick walls flexural failure is improved evidently through making reasonable reinforcement schemes.
