［摘要］鋼-混凝土雙面組合作用連續(xù)梁是一種新型組合梁，采用ABAQUS有限元軟件以變參數(shù)的方式對(duì)其進(jìn)行了有限元模擬，共開展了10個(gè)有限元模型的研究分析，并據(jù)此進(jìn)行試驗(yàn)設(shè)計(jì)。模型的變化參數(shù)包括下部混凝土板的寬度、厚度和長(zhǎng)度。分析結(jié)果表明：下部混凝土板厚度、長(zhǎng)度和寬度均對(duì)組合梁剛度影響較大；  對(duì)組合梁極限承載力影響較大的參數(shù)只有下部混凝土板厚度；  與鋼-混凝土單面組合作用連續(xù)梁相比，鋼-混凝土雙面組合作用連續(xù)梁在剛度和承載力方面有明顯優(yōu)勢(shì)，具有較大的工程應(yīng)用價(jià)值。

Abstract:The steel-concrete double-sided composite continuous beam is a new type of composite beam. Finite element simulation in a variable-parameter manner  was carried out by using ABAQUS finite element software, and 10 finite element analysis models were carried out, and the experimental design was carried out according to the simulation results. The variation parameters of the model include the width, thickness and length of the lower concrete slab. The analysis results show that the thickness, length and width of the lower concrete slab have a great influence on the stiffness of the composite beam; the parameters have a greater influence on the ultimate bearing capacity of the composite beam are only the thickness of the lower concrete slab. Compared with the conventional steel-concrete single-sided composite continuous beam, the steel-concrete double-sided composite continuous beam has obvious advantages in rigidity and bearing capacity, and has great engineering application value.

Keywords:steel-concrete double-sided composite continuous beam; composite beam;  experimental design; stiffness; ultimate bearing capacity
