【摘要】 分析了方钢管混凝土结构的优点:具有塑性变形能力强、延性好、抗震性能优良等特性,并克服了其他钢结构(如H形钢结构、圆钢管结构)由于截面形状特殊带来的设计、施工及使用功能上的不便,成为住宅结构应用发展的方向.并进一步基于钢-混凝土组合理论,给出了钢管混凝土的承载力计算公式,并对方钢管混凝土异形柱在未来钢结构住宅结构中的应用提出了研究推广建议.更多还原

【Abstract】 This paper introduces that Concrete-Filled rectangular tubular (CFRT) structure has a good ductility, plasticity, anti-earthquake, and so on. While Concrete-Filled circular tubular structure and H-shape steel structure take a lot of in- convenience in engineering design, construction and application because of it’s particular section. So CFRT structure be- comes the representation of multi-story steel-frame structure. The article deduces a set of equations for calculating CFRT bearing capacities by combine theory.Another irregular CFRT column is told and it is important in the use of future Housing building of steel structure.更多还原
