While design beam RCDC provide min 3 no of bars in the moment area how to bypass this check .There should be option in the RCDC to consider or not to consider this clause ?
As shown in the above snap, you can set the minimum number of bars for each section size and RCDc will try to match the number if other criteria like strength, minimum spacing etc. are met.
in 300 mm width beam you cant place 2 bars as per RCDC you have to place 3 minimum even though it is fulfill your requirement
share the RCDC model here.
OK I will share
Hi,if you are using the IS 456 code, then RCDC checks the maximum spacing between main reinforcement as per Table 15. refer below snap,for 300mm width, if you are trying to provide only 2 rebars, RCDC will not accept it if it is exceeding above marked values for a given reinforcement grades.
if some wants to ignore this particular as many clause staad is ignored or give freedom to user to allow this or not may be helpful
