摘要
提出不锈钢(薄壁外层)-混凝土-钢双壁空心管(DSTM)新型构件。借鉴钢-混凝土组合结构构件的基本假定及材料本构关系,分析DSTM正截面受弯承载力性能。利用截面分层法建立DSTM管纯弯构件承载力计算公式,并采用有限元数值计算方法对截面分层法计算结果进行比较分析。结果表明,两种方法所得结果基本吻合,所建立的公式可为工程设计提供参考依据。
A new type of stainless steel （ Outer thin wall） - concrete - steel double walled hollow tube is presented in this paper. By using the basic assumption of the composite structural elements and the constitutive relation of the materials, this paper analyzed the bending bearing capacity of the normal section. Using the cross section method, the calculation formula of the bearing capacity of the bending members（DSTM） is established. Beside that, the finite element numerical method is used to analyze the results of the cross section method. The study show that the results of the two methods are basical- ly consistent, and the formula can provide reference for engineering design.
