RCC Structures Design According to I.S. : 456, slabs which span in two directions with corners held down, are assumed to be divided in each direction into middle strips and edge strips such that the width of the middle strip, is Four-fifth of the width of the slab Two-third of the width of the slab Three-fourth of the width of the slab Half of the width of the slab Four-fifth of the width of the slab Two-third of the width of the slab Three-fourth of the width of the slab Half of the width of the slab ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design In testing a pile by load test, pile platform is loaded with one and half times the design load and a maximum settlement is noted. The load is gradually removed and the consequent rebound is measured. For a safe pile, the net settlement (i.e. total settlement minus rebound) per tonne of test load should not exceed 25 mm 20 mm 15 mm 10 mm 25 mm 20 mm 15 mm 10 mm ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If a bent tendon is required to balance a concentrated load W at the centre of the span L, the central dip h must be at least WL/3P WL/4P WL/2P WL/P WL/3P WL/4P WL/2P WL/P ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design A pre-stressed rectangular beam which carries two concentrated loads W at L/3 from either end, is provided with a bent tendon with tension P such that central one-third portion of the tendon remains parallel to the longitudinal axis, the maximum dip h is WL/3P WL/P WL/2P WL/4P WL/3P WL/P WL/2P WL/4P ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If ‘A’ is the sectional area of a pre-stressed rectangular beam provided with a tendon pre-stressed by a force ‘P’ through its centroidal longitudinal axis, the compressive stress in concrete, is P/2A P/A A/P 2A/P P/2A P/A A/P 2A/P ANSWER DOWNLOAD EXAMIANS APP
