SRC-RC转换柱的刚度计算

The stiffness calculation of SRC-RC transfer column

首先对我国现行SRC-RC竖向混合结构过渡层的设计要求和相关规定提出了不同的看法,建议采用SRC-RC转换柱进行型钢混凝土柱到钢筋混凝土柱的过渡。介绍了SRC-RC转换柱的优点,并在RC柱和SRC柱截面抗弯刚度基础上根据抗弯刚度等效原则合成SRC-RC转换柱的截面抗弯刚度。最后给出了SRC-RC转换柱侧移刚度计算公式。

At first,the paper puts forward different opinions for designing requirement and relative rules about SRC-RC vertical composite buffer layor of structure,it suggests that we can adopt SRC-RC transfer column to buffer from SRC column to RC column.The paper introduces advantages of SRC-RC transfer column,and it synthesizes sectional flexural stiffness of SRC-RC transfer column on the basis of RC column and SRC column sectional flexural stiffness according to flexural stiffness principle of equivalence.Finally,it provides lateral stiffness formation of SRC-RC transferring column.
