摘要
提出了内、外钢管的强度降低系数和内填混凝土的强度提高系数，并利用弹性理论的方法导出了同种双钢管混凝土轴心受压短柱在极限状态下的承载力，从而揭示了这一新型结构的力学工作性能，为这一结构的推广和进一步研究打下基础。
The strength-reducing coefficient of double steel tubes and the strength-increasing coefficient of the concrete filled are proposed in this paper. According to the elastic theory,the ultimate strength of concrete filled double tubular columns is developed under the ultimate state.Accordingly, the behaviors of of this new kind of structure are revealed. This lays a basis for the further study and application of this structure.
