Punching shear in concrete slabs is a serious problem in certain structural systems, such as flat slabs. Current analysis is based either on empirical and simplified analytical techniques or on theoretical models, mainly based on the theory of plasticity. This paper presents a new model, based on...
However, the decreased punching shear capacity resulted in failure only during the event of a fire. The following aspects are considered in this paper: Considering the response of complete concrete structures during fire, several factors can increase the sensitivity of flat slabs with respect to ...
In RF-PUNCH Pro, enlarged column heads can be arranged at point-supported punching shear points, thus increasing the shear force resistance of a reinforced concrete floor. In the following article, we will show the punching shear design with the optional

The first "Phase I" consisted of testing ten interior square slabs axially loaded. The second "Phase II" consisted of testing four specimens under eccentric loading to study the influence of moment transfer at the slab-column connection on the punching shear failure of the slabs. The main ...

Two cooling methods are employed; gradual cooling in air and sudden cooling with water applied directly to the heated surface of the slabs. It was found that exposure of slabs to fire resulted in a reduction of up to 18.3% and 43% in cracking loads and ultimate punching loads, respectively...
