摘  要:
本研究主要研究偏压荷载下方钢管再生混凝土柱的弹性抗弯刚度。采用目前国内外各规范、规程中的弯曲刚度公式,用试验得到的数据算出钢管再生混凝土柱的跨中挠度,并与试验值比较,进而推荐钢管再生混凝土柱的抗弯刚度公式。结果表明:小偏压时,推荐韩林海《现代钢管混凝土结构技术》弹性抗弯刚度的计算公式;大偏压时,推荐AIJ(1997)弹性抗弯刚度的计算公式。

摘  要:
This paper studies on the elastic flexural rigidity of recycled concrete-filled square steel tube under eccentric load.The research respectively applied the flexural rigidity formula in both Chinese regulations and international protocols,and calculated mid-span deflection values of recycled concrete-filled steel tube column with data obtained from experiments.Compared with the experimental values,thus the flexural rigidity formula of recycled concrete-filled steel tube column is recommended.The conclusions drawn are:under small eccentric load,the calculating formula of elastic flexural rigidity in Han Linhai's Modern Structural Technologies of Concrete-filled Steel Tube is recommended;under large eccentric load,the calculating formula of elastic flexural rigidity in AIJ(1997)is recommended.
