Physics · Design of Concrete Structures
As per IS 456 : 2000, the design strength (ultimate axial load capacity Pu) of a short axially loaded compression member with minimum eccentricity is expressed as: (Where fck = characteristic compressive strength of concrete, Ac = area of concrete, fy = characteristic strength of compression reinforcement, and Asc = area of longitudinal reinforcement for columns)
- 1[0.4fckAc + 0.67fyAsc]✓
- 2[0.87fscAsc + fckAc]
- 3[0.87fckAc + fscAsc]
- 4[0.45fscAsc + fckAc]
Correct answer
[0.4fckAc + 0.67fyAsc]
