Experimental study on flexural behavior of steel wire mesh concrete sheet
In order to study the influence of steel wire mesh on the flexural behavior of concrete sheet,six concrete sheets were designed and produced for flexural behavior testing,the destruction pattern of concrete sheets under 1/3 plate span concentration load was analyzed,and the influence of steel wire mesh on the cracking load,crack width and spacing,and ultimate bearing capacity of concrete sheets was studied.The results show that adding steel wire mesh in concrete sheets can improve the crack resistance of concrete sheets,reduce the crack spacing and width of ordinary concrete sheet by an average 25%.At the same time adding steel wire mesh on the cracking load and the bending bearing capacity of the concrete sheets is also have certain ascend,the maximum lift of the cracking load reaching 2.17 times and the maximum increase of ultimate load reaching 1.44 times.The smaller the mesh of steel wire mesh size,the better the lifting effect.On the basis of experimental research,considering the constraint effect of different sizes of steel wire mesh on concrete,the recommended formula for calculating the bending bearing capacity of composite steel wire mesh concrete sheets was deduced.
