【摘要】:在疊加原理求解法基礎(chǔ)上,提出簡便且滿足精度要求的連續(xù)箱梁剪力滯效應(yīng)實用計算法—固定端法,推導(dǎo)出連續(xù)箱梁在恒載(均布荷載)作用下的剪力滯系數(shù)計算公式。通過與解肢法、疊加法以及有限元分析結(jié)果的比較,本方法可靠,適用性強(qiáng),適用于薄壁連續(xù)箱梁剪力滯的計算。
[Abstract]:Based on the solving method of superposition principle, a simple and convenient method for calculating shear lag effect of continuous box girder is presented, which is called fixed end method. The formula for calculating shear lag coefficient of continuous box girder under the action of dead load (uniform load) is deduced. The method is reliable and applicable to the calculation of shear lag of thin-walled continuous box girder by comparing with the results of limb method, superposition method and finite element analysis.
