According to both current and revised rules, 16 configurations with relatively deep beam and "weak" concrete slab exhibited allowable slip values s max significantly higher than 6 mm. Therefore, the authors proposed a reduction of the maximum degree of utilization to these special cases. If the ...

In the flexural design of reinforced concrete beams, apart from the provision of adequate strength, it is also necessary to provide a certain minimum level of ductility. Traditionally, this has been done by limiting the tension steel ratio or the neutral axis depth to no more than certain fixed...
The current design codes for concrete structures suggest the minimum torsional reinforcement ratio to induce minimum ductile failure after cracking in reinforced concrete (RC) members subjected to torsional moment. However, as the member strengths are quite often lower than the torsional cracking moment...
On the basis of the exposition on the calculation formula of shear capacity in the code for design of concrete structures(GB50010—2002),the placed condition of the minimum of stirrup reinforcement ratio is discussed.And the placed condition of the minimum of stirrup reinforcement ratio is put fo...

This study aims to investigate the feasibility of eliminating the minimum shear reinforcement in reinforced sustainable high-strength concrete (HSC) beams by incorporating 0.75% (by volume) of hooked steel fibers. To do this, five large reinforced HSC beams, with and without stirrups and steel ...
The optimum cost design of under-reinforced concrete beams is considered by treating all the design parameters as random variables. The design is considered to be safe and adequate if the expected moment capacity of the beam exceeds the design moment capacity by a certain number of standard ...
