Direct Punching Shear Strength Model for Interior Slab-Column Connections and Column Footings with Shear Reinforcement

Failure Analysis of Column-Slab Connections with Stud Shear Reinforcement

Evaluation of the Efficiency of Shear Studs for Punching Shear Resistance of Slab-Column Connections

Drift Capacity Models and Shear Strength Degrading Models for Slab-column Connections

Data collected from shake table tests of two, approximately one-third scale, two story flat plate frames utilizing shear reinforcement, as well as data from prior tests, were evaluated to assess the inter-story drift ratios when punching failures occur for reinforced concrete and post-tensioned slab-column connections with and without shear reinforcement. The drift ratios at punching for the sh...

Strength of Footing with Punching Shear Preventers

The punching shear failure often governs the strength of the footing-to-column connection. The punching shear failure is an undesirable failure mode, since it results in a brittle failure of the footing. In this study, a new method to increase the strength and ductility of the footing was proposed by inserting the punching shear preventers (PSPs) into the footing. The validation and effectivene...

Estimation of Punching Shear Capacity of Concrete Slabs Using Data Mining Techniques

Punching shear capacity is a key factor for governing the collapsed form of slabs. This fragile failure that occurs at the slab-column connection is called punching shear failure and has been of concern for the engineers. The most common practice in evaluating the punching strength of the concrete slabs is to use the empirical expressions available in different building design codes. The estima...
