The results of the performed experimental studies show that the design model of SP 63.13333.2012, when calculating for punching, does not take into account the influence of the geometrical shape of the column, which can lead to a decrease in the structural safety of the flat slabs of ...
In order to show the importance of considering progressive collapse in building design, the objective function (weight or cost) to implement the requirements of UFC is presented in compare to the objective function of the traditional design of the same example without considering the progressive ...
The results of experimental study showed that the punching shear resistance increased when using steel collars with respect to control slab between (41 to 77) % when the thickness of steel collar had increased.AIP Conference ProceedingsAhmed Aziz AbdulhusseinMohannad H. Al-Sherrawi...

punchingreinforced concreteshear reinforcementstirrupThe existing punching shear design provisions according to current codes have either a semi-empirical (e.g., Eurocode 2) or a more physical (e.g., Model Code 2010) background. Although the design procedures are very similar, the predicted ...
Underground parking structures often consist of flat slabs connected by columns, for which punching shear is often the most critical design criterion. In fire conditions, the punching load can increase due to restraint of the thermal curvature of the slab or due to the expansion of the columns....
A new approach predicting the punching shear capacity of FRP reinforced concrete flat slabs without shear reinforcement is introduced in the light of the results of an experimental program conducted at the Center for Cement and Concrete of the University of Sheffield. The new approach is found to ...
