The proposed modeling strategy aims at providing reliable predictions of flexural responses of RC members with a focus on concrete cracking behavior and crushing failure, which serve as the ...
The three failure mechanisms have very different crack patterns and overall mechanical responses: from brittle flexural collapse, typical of under-reinforced RC beams, to ductile behavior with the formation of plastic hinges, typical of lightly-reinforced RC beams, to brittle failure ruled by concrete crushing, typical of over-reinforced RC ...
The crushing mode of reinforced concrete beams was spalling of the external concrete protective layer, and the crushing mode of reinforced concrete columns is formation of one main crack in the extended longitudinal direction. Multiple cracks also appeared in the transverse direction of the columns, but the width of the …
Results of an experimental investigation of isolated reinforced concrete structural walls subjected to inelastic load reversals are discussed and evaluated. Walls subjected to significant inelastic deformations and with strengths limited by concrete crushing of the web after flexural yielding are considered in this paper. It is shown that web crushing …

The present study pertains to the load-deflection behavior and cracking moments of concrete beams with hybrid FRP-steel reinforcement. Under and over-reinforced hybrid beams were tested for failure along with reference beams with only steel or FRP reinforcement. The first-cracking moments of the beams were estimated …
The crushed concrete was similar to that in the sieve size of 40 mm qualitatively. Fig. 10 shows the photo of crushed concrete in the sieve size of 10 mm, which is in ranging from 10 to 20 mm. The most fibers were removed in this case. Fig. 11 shows the photo of crushed concrete in the sieve size of 2.5 mm, which is in ranging from 2.5 …
