Abstract A group of finite element models, reinforced circular hollow section (CHS) T-joints, are established to investigate the fire resistance compared with the un-reinforced by using finite element program ABAQUS in this paper. Sequentially coupled thermal-stress analysis is used to simulate the process of tubular T-joint under different loading levels in the condition of fire. The heat properties of the steel use the specified values in Eurocode 3. The fire resistance performance of collar plate reinforce CHS T-joints and the un-reinforced models are studied under different loading levels. The applied loads are 20%, 40%, 60% and 80% of the static strength… More >
