Question

An angle section is to be used as a diagonal bracing in a wall bracing system of an industrial building. The bracing member is subjected to a design tension force of N_t* = 175 kN.

Choose a section to satisfy yielding requirements, and then check the section capacity based on the ultimate strength (i.e. check the fracture limit state at the connection).

Assume ϕ = 0.9, k_t = 0.85
