Punching shear is the most common failure mechanism of slabs that are supported directly on columns. The slab–column connection always vulnerable to critical punching shear; thus, it necessary investigate effect various parameters behavior flat slabs. This work presents an experimental study evaluate level prestressing force and layout strands in terms maximum load, deflection, stiffness, ducti...

Abstract In this study, the response of ten composite post-tensioned concrete beams topped by a reinforced deck with adequate reinforcing shear connectors is investigated. Depending on compressive strength slab (20, 30, and 40 MPa), are grouped into three categories. Seven these exposed to fire attack 700 800 °C temperature simultaneously or without presence uniformly distributed sustained stat...

The performance of precast shear wall panel structures subjected to earthquakes relies on the behaviour and integrity of the connections between the panels. The current lack of knowledge on the seismic behaviour of precast wall connections limits the use of such systems in earthquake areas. This paper presents results of an extensive experimental program undertaken at the University of Manitoba...
