Development of thermal stress in high rise building structure exposed to fire is localized around fire compartment in which fire occurs. Behavior of thermal stress in local substructure directly exposed to fire is extended to elasto-plastic and creep range though it is limited in elastic range on adjacent substructure at a few floor and span distance from fire zone and at further distance the influence of thermal expansion is negligible. In this paper, we suggest calculation method of restrained forces acted to local substructure and deflections of adjacent substructure. These forces are enable to investigate exact total structural stiffeness and forces. Additionally, those deflections are enable to estimate thermal stress of adjacent substructure rapidly, following to the nonlinear analysis of local substructure at each time.
