钢管混凝土抗弯刚度的分析及应用

Analysis and Application of Flexural Stiffness for Concrete-filled Steel Tubes

对在受压区和受拉区配筋的钢管混凝土柱和不配筋钢管混凝土柱抗弯刚度进行计算分析,并考虑了计算抗弯刚度中钢材强度、含钢率和混凝土强度等级的影响,研究结果表明,配筋钢管混凝土柱的抗弯刚度和抗弯承栽力比不配筋钢管混凝土柱抗弯刚度有明显提高。结论对大型广告牌的设计有一定的指导意义。

In this paper, the flexural stiffness of concrete filled steel tube column that was reinforced in compression and tension area and concrete-filled steel tube column are calculated and analyzed. Steel ratio, strength of steel and strength of concrete are considered in calculation. The researching works show the flexural stiffness of reinforced concrete filled steel tube is higher than concrete filled steel tube. The conclusion acquired in this paper provides some advices for the design of large advertising board.
