Residual properties of three-span continuous reinforced

This paper presents an experimental study on the post-fire residual behavior of continuous reinforced concrete (RC) slabs. The mechanical performance of five post-fire continuous RC slabs is investigated, including load-deflection curves, concrete and reinforcement strains, …

Structural behavior of reinforced concrete one-way slabs

The ability of reinforced concrete elements to absorb energy before exhibiting a remarkable drop in the load-carrying capacity is called toughness. The toughness is a very important criterion for reinforced concrete members susceptible to seismic load or impact load . Thus, assessing the effect of voids on the toughness of slabs is very crucial.

Evaluating the fire endurance of concrete slabs reinforced

It is extremely important to recognize that, while the steel reinforced concrete slab is assumed to fail by concrete crushing after the steel yields, both of the FRP-reinforced slabs are assumed to fail by FRP rupture prior to concrete crushing.

Experimental response and code modelling of continuous

Slab C–S–UU was reinforced with four steel bars of 10 mm diameter (under reinforced) on both the bottom and top sides to achieve a typical ductile failure mode by yielding of steel reinforcement first, followed by concrete crushing.

Service performance of steel fiber reinforced concrete

The thinner slab specimens, s7505-, exhibited crushing at a consistent displacement of 1.0 in. (25.4 mm). Observed concrete crushing for the thicker specimens was not consistent, ranging from displacements of 0.6 to 0.9 in. (15.2–22.9 mm). For each specimen, the compression region above the primary crack was the first to exhibit crushing.

Punching Shear Behavior of Reinforced Concrete Slabs

has influence on level of reinforcing steel temperature of slabs. The temperature of slabs with thin concrete cover (10mm) increased more than those with (25mm) cover by about (61% to 84%).

10 Design Optimization of Reinforced Concrete Slabs

A reinforced concrete slab is a key structural component and is used in houses to provide flat surfaces (floors and ceilings). Concrete slabs are effective systems where putting columns interrupts the structure's (Audiences, parking lots, hotels, airports, etc.) serviceability to cover the lengthy spans.
