Experimental Study On Crack Strengthened Of Masonry Wall

In this paper , the researching and developing situation at home and abroad on cement mortar reinforced with steel mesh used in aseismic reinforcement are firstly reviewed .Based on experiments on three brick walls unstrengthened and strengthened , the forces , deformations and damaged patterns of walls bearing vertical and cyclic horizontal loads of multi-storey brick buildings are discussed . The effect of cement mortar reinforced with steel mesh upon the strength and deformation characters of walls are analyzed through comparing strengthened walls' experiments with unstrengthened walls' . It is set forth that the measure has different results on enhancing walls' bend and shear strength . the test study of the brick wall cement mortar reinforced with steel mesh indicates : when the consolidated brick wall fail in bending-shear , its ultimatehorizontal load and drift stiffness respectively is 1.5 and 2 times bigger than that of brick wall. Besides , with stated heightand brendth ratio , acted on by horizontal and vertical load , the ultimateloads of wall failed in bending-shear is similar to one failed in shear. The walls crack form is indefinite . we can't define consolidate menthod only by the crack from. In the end, based on test results and practice project, cracks of Masonry wall are strengthened .
