Abstract A numerical procedure is proposed for asymmetrical plastic shear diagrams in punching control perimeters. Asymmetrical occur edge and corner columns internal with biaxial unbalanced moments. The intends to support the use of NBR 6118, which covers distributions due moments columns. study different positions slab proves robustness efficiency proposal. practical application tested agains...

Abatraet--A model predicting the number of prismatic loops dislocation punched at the ends of a cylindrical fiber by thermal mismatch stresses is presented. The longitudinal stress in the fiber is derived as a function of the distance from fiber center using the shear-lag model for the elastic portion of the interface. We show that there is a critical fiber length above which the number of loop...

Abstract The Critical Shear Crack Theory (CSCT) has been developed since 1985 to assess the shear resistance of members without reinforcement and punching reinforced concrete slabs in a rational manner. main idea CSCT is that governed by development critical crack, its geometry kinematics. Recent tests with detailed measurements have confirmed force can be carried through crack combination aggr...
