型钢混凝土柱设计方法与施工工艺研究

为探索型钢混凝土柱的设计方法与施工工艺,分别对轴心受压、偏心受压的正截面承载力和斜截面承载力进行分析,给出了建议的承载力计算公式,并绘制了实用的简化型钢混凝土柱表供设计使用;对型钢混凝土柱的保护层厚度、最小配箍率、轴压比进行了研究,从构造要求上对型钢混凝土柱的抗震性能进行控制;同时,总结了型钢混凝土柱的关键施工工艺,并对施工中可能遇到的钢筋冲突问题给出了建议。

Study on Design Method and Construction Technology of Section Gteel Reinforced Concrete Golumn

To explore the design method and construction technology of section steel-reinforced concrete columns,the normal section bearing capacity and inclined section bearing capacity of axial compression and eccentric compression are analyzed respectively,the recommended bearing capacity calculation formula are given,and a practical table of simplified steel-reinforced concrete columns is prepared for design.The thickness of protective layer,the minimum stirrup ratio and the axial compression ratio of the section steel-reinforced concrete columns are studied,and the seismic performance of section steel-reinforced concrete columns is controlled from structural requirements.At the same time,the key construction technology of steel-reinforced concrete columns is summarized,and some suggestions for the possible conflict problems of reinforcing steel bar encountered in construction are given.
