Question

In the design of a steel tension member, which mode is NOT typically considered?

• A. Yielding of gross section
• B. Rupture of net section
• C. Block shear failure
• D. Buckling of compression flange

Hint:

In tension member design (IS 800:2007), always check for: \item Yielding of gross area (\( T_y = A_g f_y / \gamma_m0 \)) \item Rupture of net section (\( T_r = 0.9 A_n f_u / \gamma_m1 \)) \item Block shear failure (\( T_{bs} \))

Answer 1

The Correct Option is D

In the analysis and design of steel tension members, the following failure modes are typically checked: 
Yielding of the gross section – governs the plastic deformation before failure. 
Rupture of the net section – occurs at bolt holes or net cross-sections. 
Block shear failure – a combined mode involving tension and shear rupture along specific planes. 
However, buckling of the compression flange is a failure mode related to compression members, especially in flexural members (like beams), not tension members. 
Thus, it is not applicable in the context of a tension member design.
