RCC Structures Design The load stress of a section can be reduced by Replacing larger bars by greater number of small bars Replacing smaller bars by greater number of greater bars Decreasing the lever arm Increasing the total perimeter of bars Replacing larger bars by greater number of small bars Replacing smaller bars by greater number of greater bars Decreasing the lever arm Increasing the total perimeter of bars ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If the modular ratio is ‘m’, steel ratio is ‘r’ and overall depth of a beam is ‘d’, the depth of the critical neutral axis of the beam, is [m/(m - r)] d [(m + r)/m] d [(r - m)/m] d [m/(m + r)] d [m/(m - r)] d [(m + r)/m] d [(r - m)/m] d [m/(m + r)] d ANSWER DOWNLOAD EXAMIANS APP
