The weld coefficient - a new parameter accounting for shear resistance of welded wire mesh in place of conventional stirrups as shear reinforcement in RC beams

Abstract

A vast majority of structural elements such as Reinforced Concrete (RC) beams loaded with transverse loads develop both shear and bending moments at different sections along their span. From the safety point of view the RC beams must be designed to have adequate safety margin against various kinds of failures. Keeping in view of the nature of the shear failures which are in general associated failure with little or no advanced warning, the design for shear in RC members normally ensure that the shear strength for every member in the structure exceeds the flexural strength. The shear failure mechanism depends upon the cross-sectional dimensions, the geometry, the types of loading, and the properties of the member1-3.
