D8.B.3.4 Combined Stress
Members subjected to both axial and bending stresses are proportioned accordingly to section 7 of IS:800. All members subject to bending and axial compression are required to satisfy the equation of Section 7.1.1.(a) for intermediate points, and equation of Section 7.1.1.(b) for support points.
For combined axial tension and bending the equation of Section 7.1.2. is required to be satisfied.
Cm coefficients are calculated according to the specifications of Section 7.1.3. information regarding occurrence of sidesway can be provided through the use of parameters SSY and SSZ. In the absence of any user-provided information, sidesway will be assumed.
