RCC Column Minimum Reinforcement ???
RCC Column Minimum Reinforcement ???
(OP)
I am designing a RCC column and under the loading (moment +axial) 250mmx250mm size of column is enough but due to the anchor bolt concrete cover requirements I need to increase the column size 750mmx750mm so my question is that I need to place the minimum area of reinforcement in the column according to the 250mmx250mm or 750mmx750mm.
If I follow 750x750 the minimum area of steel bar (1% x Ag) will be too much, so any one can provide the better solution in this regard???
thanks in advance

hokie - do you really use .5%? All the OG's trained us to stick with 1%. They only let us use .5% for lightly loaded pedestals.

Yes. Not sure of the OP's code, but some do allow 0.5 percent of the oversized section.
