Abstract: This paper lays out three planed sections of the concrete-filled rectangular steel tube arch, and analyzes the intemal force of the section and the mechanical stability of the member, analyzes the initial stress and the thermo-effect, finally, selects the best plan of the section in both of mechanical performance and economic performance.
Keywords: equivalent beam-column method; initial stress; range of temperature during a year; range of temperature during a day
