Hi,

the guidelines are given in the code for maximum spacing are in view of controlling cracks in the beam. thus, the maximum spacing reduces if we use higher reinforcement grade.
We would suggest user to follow the guidelines given in the code.

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.

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

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.
