Design codes specify minimum flexural reinforcement for reinforced concrete beams. With the extensive use of higher strength concrete, the empirical expressions of the past for minimum flexural reinforcement, in which the concrete strength is not considered, had to be revised. Six reinforced concrete T...
An experimental investigation was conducted on the behavior of thirteen high-(HSC) and normal-strength concrete (NSC) full-size beams with relatively low amounts of torsional reinforcement. The crack patterns, the maximum crack widths at service load level, torsional strength, torsional ductility, an...
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...

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 ...
