This project proposal will draw up the short-term, mid-term and long-term research plans in nine years based on the capacity of the fire lab of ABRI in Tainan and the each term covers three years. One or two research topics will be planed in each year. The planned topics will focus on studying the structural behaviors of SRC and steel composite structures in fire and investigate the important parameters affecting the mechanical behaviors in fire. The most economical experiments will be designed during nine years. This research will invite Prof. Michael D. Engelhardt from the University of Texas at Austin to participate in some research topic planning for international collaboration.
