i will sent you a screenshot
Hi,Please check this option available in RCDC where actual number of bars are available in design calculation reports and drawings.
above marked option gives the actual number of rebars to be provided.
ok but is should reported as actual that is calculated by manually in drawing we are not writing how much bar is placed instead of it we write 10@ 225 or 200 this is wrong . whoever in calculation of quantity this no of bar +1 is taken not in Ast calculation. I hope you get my point
Dear Sir,Please share the design calculation report to give the clarification of 250mm spacing. it must be maximum spacing allowed in the footing reinforcement setting for calculated for the Ast.when we provide the rebars on site, to maintain the spacing we always provide the n+1 rebars. in your case, the number of rebars required as per Ast are 6, however on site finally 7 rebars will be provided to maintain the spacing. Now for the width of 1500mm there are 7 rebars are provided. so, if we recalculate the Ast provided for 1500mm width is more than the actual required.
but how this 250 spacing was coming ? as we know spacing is calculated from following formula
spacing = (area of one bar * length of footing) /Ast then in my case if i am using the 10 mm dia bar the 78.5*1500/497 + 236 spacing while rcdc reported 250mm
