Minimum Reinforcement on Grade Beams
Minimum Reinforcement on Grade Beams
(OP)
Hi i Wanted to know about the minimum reinforcement on grade beams. we ussually use the minimum reinforcement for shrinkage and temperature. I wanted to know if this is ok or if we´re missing something. The amount of steel with this minimum reinforcement is huge compared with the requiered reinforcement per calculations.
As always,Thanks a lot

i would like to know what is the minimum reinforcement for this elements.
By the way,We ussually design continuos footings as a grade beam and we specify the minimum reinforcement requiered by temperature or shrinkage. i´d like to know if we could specify only the requiered by calculations or which is the minimum percentaje of steel requiered for continuos footings

By AS3600 this basically means that the ultimate strength in bending should be 1.2x the concrete cracking moment.

I'm curious, are the moment frame columns supported by the grade beam or do those columns bear over piers?

The Columns pass through the beam and are supported by a pad footing. The grade beam takes the moment of the column with a the couple generated by threaded rebars welded to the flanges of the steel columns and the compresion on the concrete.The footing takes all the axial load and both with the passive earth pressure and friction takes the shear forces
