（揚州大學工學院 225009）[提要] 鋼筋混凝土梁在長期荷裁作用下的非線性變形一直是研究老、感興趣的課題。本文闡述了如何分別考慮荷載、混凝土徐變與收縮對鋼筋混凝土梁的變形影響，其中直接應用了作者導出的混凝土徐變和收縮相關系數的實用公式。
[關鍵詞] 鋼筋混凝土 梁 徐變 收縮 變形The deflection of reinforced concrete beam under long-term loads is non-linear, which has been interesting to civil engineers. This paper describes the deflections of reinforced concrete beams due to loads. creep and shrinkagc. The practical expressions of creep and shrinkage factors are derived.
Keywords: reinforced concrete; beam; creep; shrinkage; deflection
