Secant formula is used for the determination of allowable stress in axial compression.
Different formulas used for finding allowable stress in axial compression are as follow;
Before IS800;1984 secant formula used.
@IS800;1984 Rankine formula used.
IS800;2007 perry Robertson formula used.
Secant formula is fc=(fy/m)/[(1+0.20sec(l/r(mfa/4E)^0.5))].
