The Building is designed including EQ loads and STAAD RCDC is giving more reinforcement at bottom near supports as curtailed bars. Why?

RCDC design the beams as per section forces available from analysis. It designs the beams at 13 stations for given load combinations. When lateral loads are applied, due to sway effect end moment exists at end of the beam. So generally for +ve Eq and -ve Eq loads, the heavy moment exists at top or bottom of the end of the beam. You need to check the detailed design calculation report to get more information about the beam design. The report will contain information on which moment has been used for the calculation of end reinforcement.
