| 摘 要： | 目的得到钢骨-钢管混凝土柱正截面承载力计算表达式.方法分别考虑钢骨混凝土部分和钢管混凝土部分各自承担的轴力和弯矩,将这两部分的轴力、弯矩叠加.钢管混凝土部分按照现行的钢管混凝土公式计算;钢骨混凝土部分采用简化分析,按照忽略环箍效应和考虑环箍效应两种情况计算,同时和按照叠加方法计算的钢管混凝土组合柱承载力进行比较.结果钢骨-钢管混凝土柱正截面承载力比钢管混凝土组合柱承载力提高约15%,叠加的计算方法可以适用于钢骨-钢管混凝土柱.结论钢骨-钢管混凝土柱具有更高的承载力能力和更好的延性.

| Abstract: | The study aims to get the calculation formulas of normal section strength of circular steel tube composite short column filled with steel reinforced concrete.The circular steel tube composite short column filled with steel reinforced concrete was divided into the concrete filled steel tube and the steel reinforced concrete.With the superposition method,the axial force and flexural strength of corresponding parts were calculated respectively.The universal theoretical method of concrete filled steel tube was applied to the section of concrete filled steel tube column.With simplified analysis of steel reinforced concrete column,two methods were considered concerning the steel reinforced concrete.Then,corresponding computing results and experimental results were compared.The result shows that the superposition method can be used in the calculation of circular steel tube composite short column filled with steel reinforced concrete.We obtain the calculation formulas of normal section strength of circular steel tube composite short column filled with steel reinforced concrete and its carrying capacity is better than that of circular steel tube composite column filled with reinforced concrete. |
