| 摘 要： | 在对圆形和方形钢管混凝土柱的研究过程中,考虑了中间主应力,推导出圆空心钢管混凝土轴心受压构件承载力的计算式,并推广到方空心钢管混凝土,得到了统一的承栽力公式,与文献资料的试验数据进行了对比,结果吻合良好,验证了统一强度理论对空心钢管混凝土柱的理论计算的适用性,为工程设计提供了理论依据.

| Abstract: | For square and circular CFST concrete cylinders,considering the effect of intermediate principal stress,formulae of compressive strength of circular centrifugal H-CFST were presented,and were developed to square CFST,then the unified formula of bearing capacity was deducted.Predictions from the derived formulae were compared with test results and satisfactory agreements were reached.It is concluded that the Unified Strength Theory is versatile in theoretical analyses of centrifugal H-CFST.The results provid... |
