Abstract
Fire resistance of square hollow section ( SHS) T-joint at elevated temperature subjected to fixed axial loading level is analyzed by using finite element analysis (FEA) . Before FEA, finite element model is established and proved to be reliable from benchmark verification with reported experimental results. Material nonlinearity and geometric nonlinearity caused by temperature have been taken into consideration in the numerical analysis. In addition , the environmental temperature is consistent with ISO834 standard heating curve and coupled thermal-stress method is used. The steel material parameters at elevated temperature are defined in according with Eurocode 3 which is widely applied in fire-resistant research work of engineering structures. In this study, some conclusions on the fire resistance of SHS T-joint are proposed. It is found that deformation of the chord and reaction force at the chord ends are changed with temperature. Additionally, the relationship between loading ratio and critical temperature is also concluded.关键词
