RCC Structures Design A simply supported beam 6 m long and of effective depth 50 cm, carries a uniformly distributed load 2400 kg/m including its self weight. If the lever arm factor is 0.85 and permissible tensile stress of steel is 1400 kg/cm², the area of steel required, is 15 cm² 16 cm² 14 cm² 17 cm² 15 cm² 16 cm² 14 cm² 17 cm² ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design Though the effective depth of a T-beam is the distance between the top compression edge to the centre of the tensile reinforcement, for heavy loads, it is taken as 1/12th of the span 1/16th of the span 1/10th of the span 1/8th of the span 1/12th of the span 1/16th of the span 1/10th of the span 1/8th of the span ANSWER DOWNLOAD EXAMIANS APP
