Flexure shear capacity of prestressed hollow core slabs

Static Flexure of Soft Core Sandwich Beams using Trigonometric Shear Deformation Theory

This study deals with the applications of a trigonometric shear deformation theory considering the effect of the transverse shear deformation on the static flexural analysis of the soft core sandwich beams. The theory gives realistic variation of the transverse shear stress through the thickness, and satisfies the transverse shear stress free conditions at the top and bottom surfaces of the bea...

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...

Punching shear capacity of reinforced concrete slabs with headed shear studs

Experimental Study on Precast Concrete Shear Walls with Different Hollow Slabs

To study mechanical behaviors of shear walls built with precast two-way hollow slabs, two shear walls with different details of hollow slabs were quasi-statically tested under low cyclic loading. The failure mode was analyzed, which vertical macro-cracks appeared on walls due to the details of hollow slabs. Brittle shear failure can be avoided in terms of the failure behaviors evolved from inte...

Influence of reinforcement arrangement in flexural fire behavior of hollow core slabs

This paper describes four standard scale fire tests conducted on precast prestressed hollow core slabs under flexure. The influence of the reinforcement arrangement was investigated using two test parameters: the average axis distance (from 30.1 to 46.7 mm), and the type of reinforcement (5 mm diameter wires and 9.5mm diameter strands). An ISO 834 standard fire was applied maintaining the load ...
