Much less consideration has been given to the performance of modern structural and architectural systems during fires and to the minimization of damage that threatens the integrity of structures during fires and the viability of structures after fires. In particular, building codes generally do not address the loads that are induced in structures and architectural components during fires. Consequently, major fires usually cause severe structural damage, even in areas remote to the fire area. Recent trends in structural design and code development are reducing the strength reserved for support of loads during fires. This paper discusses consequential loads that threaten the integrity of structural and architectural systems in major fires.
