The Flange Effect of Brick Masonry Wall Subjected to Seismic Effect

Abstract:

This paper researces the effect of flange width on anti-seismic performance of flanged brick masonry walls. Four T-shaped cross section unreinforced brick masonry walls with different flange width and one rectangular shaped cross section brick masonry wall are studied and analyzed by ABAQUS finite element method.Analyze and compare the force-displacement curves of flanged brick masonry wall under the composed of vertical and lateral load.The results indicate that the flange width has a significant effect on the shear bearing capacity and ductility. The shear bearing capacity and ductility factor of T-shaped cross section brick masonry walls with 1.6m flange width are respectively 20% and 50% higher than the no flange wall .The flange effect is obvious when the flange width is not more than 1.6m, the value of shear bearing capacity and ductility are higher when the flange width become longer.
