Concrete shear resistance enhancement factor development

Abstract

Concrete shear resistance capacity is a serious problem despite the several improvements attempts through different models. Certainly,  improvement in concrete shear assessment will prolong the structural service life. Thus, the need for more research works in order to  improve on the drawback in the current European code formulation. Therefore, this paper presents a suggestion for mitigation of shear  failure through the improvement of shear performance enhancement that employs a more rational scheme to the development of  concrete shear resistance factors. The result from the numerical examples given herein shows a considerable improvement in the  concrete shear resistance estimation of about 11%. This shows that the developed shear resistance factors will significantly improve the  EC2 shear formulation when applied.
