• If the depth of two column sections are equal, then the column splice is provided
• For the steel member exposed to weather and accessible for repainting, the thickness of steel should not be less than (excepting the webs of Indian Standard rolled steel joists and channels).
• Secant formula for direct stress in compression, is applicable only for slenderness ratio upto
• The equivalent axial tensile load Pe, which produces an average axial tensile stress in the section equivalent to the combined stress due to axial tension P and bending M, at the extreme fibre of the section, is given by (where Z is the section modulus of the section).
• When a tension member is made of four angles with a plate as a web, the allowance for holes is made as
