A bracket of length 1.5m is rigidly attached to the simply-supported beam at its end. The beam is subjected to the combined effect of M,, M, and compressive force P caused by the factored loads as shown. There are lateral supports only at the ends. The member is made of HE300A section and steel grade is S275 (F=275MPA, Fu= 430 MPa). The loads acting are determined from LRFD combinations. Determine whether the member can safely carry the applied loads. Multiply first-order moment diagrams by a factor of 1.2 to account for second-order effects. No need to check shear limit state. You do not need to additionally consider the beam self-weight.

![A bracket of length 1.5m is rigidly attached to the simply-supported beam at its end. The beam is
subjected to the combined effect of M,, M, and compressive force P caused by the factored loads as
shown. There are lateral supports only at the ends. The member is made of HE300A section and steel
grade is S275 (Fy-275MPA, Fu= 430 MPa). The loads acting are determined from LRFD combinations.
Determine whether the member can safely carry the applied loads. Multiply first-order moment diagrams
by a factor of 1.2 to account for second-order effects. No need to check shear limit state. You do not
need to additionally consider the beam self-weight.
