Extensive simulations of restrained steel beams with web openings at elevated temperatures Understanding the effects of changing opening, temperature profile, restraint level, load ratio Beams may enter catenary action at much lower than temperatures than critical temperatures. The maximum beam catenary tensile force comes from the bottom tee-section.
