| Abstract: | This paper presents theoretically how the interaction of joints and beam is developed in fire conditions.A simple practical method is proposed to couple the non-linear changed characters of composite connection in the analysis of catenary action of beams at elevated temperatures.The proposed method is verified by experimental investigations.The study offers a feasibility of fire-resisting design and evaluation for the composite beam with semi-rigid connections in the complete temperature range. |

| Keywords: | flush endplate composite joint fire-resistant capability non-linear restraint restrained composite beam design method |
