Reinforced concrete flat slabs are used worldwide in multi-story buildings. In these slabs, the design is often governed by punching shear and serviceability. The mitigation of issues during usually leads to increased raw material consumption costs. Previous studies have shown that using Fiber Concrete (FRC) or High-Strength (HSC) only at vicinity column, while casting rest slab with Normal Str...

This study evaluates the fracture properties and rear-face strain distribution of nonreinforced and hooked steel fiber-reinforced concrete panels penetrated by projectiles of three different nose shapes: sharp, hemispherical, and flat. The sharp projectile nose resulted in a deeper penetration because of the concentration of the impact force. Conversely, the flat projectile nose resulted in sha...

In order to study the basic mechanical property of cast-in-place stiffening-ribbed-hollow-pipe reinforced concrete girderless floor, and similarities and differences of the structural performance compared with traditional floor, we carried out the destructive stage loading test on the short-term load test of floor model with four clamped edges supported in large scale, and conducted the long-te...

The present paper deals with a feasibility study of Compton scattering technique for inspection of concrete structures for the detection of local defects and the discrimination between materials of different density and composition, such as concrete, void and steel. The experimental setup consists of a Cs radioactive source and a HPGe planar detector providing high resolution energy dispersive ...

In the present study, a new method for retrofitting reinforced concrete beam is introduced in which steel-concrete composite jackets containing steel fiber is used. For this purpose, 75% of the peripheral surface of reinforced concrete beams was initially reinforced using steel plates and bolts, and steel fiber reinforced concrete was used between the steel plates and the peripheral surfaces of...
