【摘要】 从柱、节点和异形柱体系三个方面,对矩形钢管混凝土的研究进行了总结。介绍了常用的三种矩形钢管混凝土柱的理论体系,即拟钢理论、统一理论和叠加理论,并利用大量试验数据,对不同理论进行了对比分析。介绍了国内常用的四种矩形钢管混凝土柱-钢梁节点构造,对其中新型隔板贯通节点的发展进行了详细阐述。介绍了异形柱的分类和研究成果,并对提出的方钢管混凝土组合异形柱方面的研究进展进行了总结。更多还原

【Abstract】 The researches about rectangular concrete-filled steel tube were summarized and introduced in terms of column,connection and special-shaped column. Three commonly-used theories including separately semi-steel theory,uniform theory and superposition theory were introduced. Enormous experimental datas were collected to compare among different theories. Four normally construction of concrete-filled rectangular steel tube column steel beam connection were introduced and the innovative through-diaphragm connections were described in detail. Furthermore,the research on special-shaped columns was reviewed and the development on the special-shaped column composed of concrete filled square tubes was summarized.更多还原
