The calculation modes of the coefficient of shrinkage and creep of the bulgy core concrete in steel tube are discussed . based on a few reasonable hypotheses and the stress - strain relation of concrete acquired by the " adjusting valid modulus depending on load time " method , a compact formula is reasoned out , which is applied to calculate the equivalent elastic modulus of the bulgy core concrete considering the affection of shrinkage and creep . so , the analysis of the affection on cfst arch bridge by shrinkage and creep can be progressed by pole - girder fem , further more , the analysis precision is quite high 本文還對(duì)核心膨脹混凝土特殊的收縮、徐變系數(shù)計(jì)算模式展開(kāi)了探討,在合理的假設(shè)前提下,采用“齡期調(diào)整的有效模量法”得到的混凝土的本構(gòu)關(guān)系,推導(dǎo)出鋼管內(nèi)核心混凝土在考慮徐變影響后的等效彈性模量計(jì)算公式,并以此為基礎(chǔ)采用桿系有限元方法來(lái)對(duì)鋼管混凝土拱橋進(jìn)行較高精度的收縮徐變分析。
