RCC Structures Design If the tendon is placed at an eccentricity e below the centroidal axis of the longitudinal axis of a rectangular beam (sectional modulus Z and stressed load P in tendon) the stress at the extreme top edge Is decreased by Pe/Z Remains unchanged Is increased by PZ/e Is increased by Pe/Z Is decreased by Pe/Z Remains unchanged Is increased by PZ/e Is increased by Pe/Z ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design The maximum shear stress (qmax) in a rectangular beam is 1.25 times the average 1.75 times the average 1.50 times the average 2.0 times the average 1.25 times the average 1.75 times the average 1.50 times the average 2.0 times the average ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design The load stress of a section can be reduced by Replacing larger bars by greater number of small bars Decreasing the lever arm Replacing smaller bars by greater number of greater bars Increasing the total perimeter of bars Replacing larger bars by greater number of small bars Decreasing the lever arm Replacing smaller bars by greater number of greater bars Increasing the total perimeter of bars ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design An R.C.C. beam of 25 cm width and 50 cm effective depth has a clear span of 6 meters and carries a U.D.L. of 3000 kg/m inclusive of its self weight. If the lever arm constant for the section is 0.865, the maximum intensity of shear stress, is 21.5 kg/cm² 8.3 kg/cm² 21.5 kg/cm² 7.6 kg/cm² 21.5 kg/cm² 8.3 kg/cm² 21.5 kg/cm² 7.6 kg/cm² ANSWER DOWNLOAD EXAMIANS APP
