A W540x150 simply supported beam 8 m long is to be loaded by a triangular distributed load that linearly increases from zero at the left end to 20 kN/m (dead) at the right end + a uniformly distributed load of 35 kN/m (live) throughout its entire span + its self-weight. It is braced laterally at the end supports. Use LRFD Provisions of NSCP 2015. Use Fy = 345 MPa. A.) Which segment of the beam will likely govern its moment capacity, and what is the corresponding lateral-torsional buckling modification factor, Cb? B.) What is the ultimate moment capacity of the beam, in kN-m

Question
A W540x150 simply supported beam 8 m long is to be loaded by a triangular
distributed load that linearly increases from zero at the left end to 20 kN/m
(dead) at the right end + a uniformly distributed load of 35 kN/m (live)
throughout its entire span + its self-weight. It is braced laterally at the end
supports. Use LRFD Provisions of NSCP 2015. Use Fy = 345 MPa.
A.) Which segment of the beam will likely govern its moment capacity, and
what is the corresponding lateral-torsional buckling modification factor, Cb?
B.) What is the ultimate moment capacity of the beam, in kN-m?
