| 摘 要： | 通过实测的钢管高强混凝土短柱的承载能力与目前常用的钢管混凝土承载能力计算公式的计算结果进行对比,从而找出适用的计算公式。结果表明,欧洲规范和Good C.D.提出的公式低估了钢管高强混凝土的承载能力;JCJ01-89提出的公式有局限性,在含钢率超过13.6%后将低估其承载能力;用我国规程CECS28-90中提出的计算公式来计算钢管高强混凝土的承载能力最为准确。

| Abstract: | An experiment was undertaken to investigate which formula is suitable for calculating the load bearing capacity of steel tubular high strength concrete based on the comparison between tested and calculated results. The test results show that formulae provided by Eurocode 4 and Good C.D.underestimate the load bearing capacity.The formula offered by JCJ01-89 also undervalue the load bearing capacity when the steel content exceeds a critical value of 13.6%.Comparatively,the formula provided by CECS28-90 is the most accurate one to calculate the load bearing capacity of steel tubular high strength concrete. |
