摘 要:钢管混凝土梁承载力优化问题一直是工程界比较关心的问题,通过引入强重比的概念,对比分析了钢筋混凝土梁构件和钢管混凝土梁构件的强重比。分析结果表明,强重比越大,构件的承载力和性能就越好。同时利用有限元软件ABAQUS对其承载力进行参数优化分析,通过参数优化分析进一步提高钢管混凝土梁的承载力,以满足实际工程的需要。
Abstract: The optimization of bearing capacity of concrete-filled steel tubular beams has always been concern of the engineering community. The strong weight ratio of the reinforced concrete beams and concrete filled steel tubular beams are comparative analyzed. The results show that the bearing capacity of the beams is increasing with strong weight ratio, and the finite element software ABAQUS is used to analyze the parameter of bearing capacity. Through the parameter optimization analysis, the bearing capacity of the concrete-filled steel tubular beam is further improved to meet the needs of actual engineering.
