高温下钢筋混凝土框架结构变形和内力的数值分析

Numeirical analysis of the deformation and the internal force of reinfoced concrete frames at elevated temperature

利用ANSYS对四榀单层单跨钢筋混凝土框架进行有限元模拟分析,得到其在高温下的变形和内力计算结果,并与前人试验、数值计算结果进行对比分析,进而定性得到单层单跨框架结构在高温作用下的变形、内力变化规律,取得了较为理想的结果,为下一步继续研究结构在高温下的其他复杂力学性能提供一定的条件。

In this paper,four single span and floor reinforced concrete frames at elevated temperature was analyzed with ANSYS.From ANSYS simulation result,the regularities of the deformation and the internal force redistribution can be gained and compared with experimental and numeral result to get the rules of the deformation and the internal force of single span and floor reinforced concrete frames at elevated temperature.Meanwhile,this paper will conduce to the further research of other mechanical performance of reinforced concrete structure at elevated temperature.
