In this respect, a literature review of the work undertaken by previous researchers on punching shear behaviour of concrete slabs is presented. After that, a constitutive model for SFRC was developed. This is followed by a preliminary finite eleme...
Punching shear performance of concrete slabs under fire A rigid-plastic model based on unified strength theory was used to calculate the effect of fire on the punching capacity of the flat slab. The calculated results fitted the test results well; thus, the rigid-plastic model can be ... DY...

Punching shear calculation procedures for column footings in the existing Standards are generally recommended on the basis of experiments performed on reinforced concrete slabs. Experimental researches of footings have hitherto rarely been conducted and they are mainly performed in laboratory conditions, in ...
Shell finite elements have been extensively used in the analysis of slabs for flexure. However, the critical issue in the design of these slabs is a 3D shear effect around the column area called punching shear. 3D elements can be used for punching shear analysis of reinforced concrete slabs, ...

The real importance of punching shear consists of a sudden brittle fracture, which can trigger catastrophic ...
This study investigates the punching shear failure of RC slabs under close-in explosions through numerical simulation and theoretical analysis. Initially, a finite element model is developed to examine the distribution of the explosion load on the slab's surface. Subsequently, the critical explosion ...
