- For determination of allowable stress in axial compression, Indian Standard Institution has adopted
- 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).
- The allowable stress in axial tension for rolled I-sections and channels, is taken as
- The allowable stress in axial tension is generally kept less if thickness of the member is more than
- An axial loaded column is supported on a slab base whose projection is 8 cm. If the intensity of pressure from concrete is 40 kg/cm2 and allowable bending stress in slab base is 1890 kg/cm2 , the thickness (t) of the slab base, is
- The allowable stress in axial tension is generally kept less if thickness of the member is more than
- If fbt and fc are the co-existent bending tensile stress and shear stress in a member, the equivalent stress fc is
- For a steel member of slenderness ratio 350, the allowable stress is 76 kg/cm2 if it is
- The economical depth d of a web plate in which allowable bearing stress is fb, and the maximum bending moment is M, as suggested by Rawater and Clark, is
- If is the maximum allowable bending stress in a tension member whose radius of gyration is and depth is 2y, the required cross sectional area is given by
