摘要
在对钢管混凝土受弯构件徐变分析的基础上,本文建立了长期荷载作用下钢管混凝土受弯构件的承载力计算方法。应用该方法对具体构件进行计算分析,认为徐变将降低钢管混凝土受弯构件的承载力,在实际工程应用中应予以考虑。
Based on creep analysis of flexural concrete filled steel tubular (CFST) members, this paper establishes a method to calculate load-carrying capacity of flexural CFST members under long-term loads. Using the method to analyze some examples, it can be considered that creep will decrease load-carrying capacity of flexural CFST, and should be taken into account in actual engineering.
