型钢混凝土组合柱正截面承载力的分析与评估

Analysis and Evaluation of Normal Sectional Load Carrying Capacity of Steel Reinforced Concrete Columns

本文采用一种可对复杂截面形式的型钢混凝土偏压柱进行截面设计和分析的数值迭代计算机 方法,首先分析了一非对称多边形角柱的正截面承载力;在此基础上,通过实例计算对《型钢混凝土组合 结构技术规程》中建议的组合柱正截面承载力简化计算方法进行了分析和评估,获得了一些对组合柱设 计有用的结论和建议。

An accurate iterative computer-method for determination of normal sectional load carrying capacity of steel reinforced concete composite columns is presented in this paper, which can be used to analyze the arbitrarily shaped composite column. Based on this, some examples are used to evaluate the simplified methods recommendded by the Technical Specification for Steel Reinforced Concrete Composite Structures. Then, several useful conclusions and suggestions for the design of this type of columns are recommended.
