| 摘 要： | 为研究不同空心率对中空夹层钢管混凝土柱的受力性能的影响,对3个不同空心率的中空夹层钢管混凝土柱试件和1个普通钢管混凝土柱试件进行了非线性有限元分析.结果表明:与普通钢管混凝土柱相比,中空夹层钢管混凝土柱承载力和刚度有了明显的提高,塑性和延性性能也相应提高.中空夹层钢管混凝土柱受力性能更加合理,它充分利用了钢材和混凝土各自受力性能的优势,大幅提高了建筑结构的安全性能,是一种发展前景非常广阔的结构形式. |

| Abstract: | In order to analysis the influence of hollow section ratio to the performance of double skin steel tubular column,the nonlinear finite element analysis was applied to three different double skin steel tubular column and a normal sample square steel tubular column specimens.The results showed that： comparing with the ordinary steel tubular column,the bearing capacity and stiffness of double skin steel tubular column were significantly improved,and the plasticity and ductility were increased accordingly.Double skin steel concrete column subjected to a more reasonable performance,It was fully used the respective advantages of steel and concrete mechanical properties.Greatly improve the safety,stability of building structures.It has a very broad prospects for development structure. |
| Keywords: | concrete-filled steel tubular safety hollow section ratio bearing capacity rigidity |
