【摘要】利用材料破裂过程分析RFPA系统,对钢骨-钢管混凝土组合柱的承载能力进行了数值模拟.通过与素混凝土柱和钢管混凝土柱的承载能力的对比,发现由于钢骨、钢管和混凝土的协同工作,该种组合柱不但具有很高的承载能力,而且延缓或抑制了混凝土中剪切裂缝的开展,提高了柱子的延性,对于提高建筑物的防倒塌能力具有重要意义.更多还原

【Abstract】 This paper,using the numerical model of material failure process(RFPA),makes a numerical investigation of the mechanical properties of axially loaded section steel and steel tube short columns filled with steel-reinforced concrete.Compared concrete with and steel tube short columns,the columns have a highly-bearing capacity and restrain the developing of the crack under shearing strength,as a result of the cooperated work of section steel,steel tube and concrete.It is important for improvement of structure mechanical properties in ductility.更多还原
