d. 1400kips;20in
The following problem description is for
A reinforced concrete flat plate floor without beams has 18 in square columns at 20ft
centers in one direction and 24ft centers in the other direction, and it supports a factored
distributed load of 200 lbf/ft2.
Design assumptions
O
o afi = afz = β = 0
O
Consider moments in the direction of the shorter span only.
af₁²7/² = 0
ACI Sec. 8.10.2 is applicable.
