［摘要］钢-混凝土双面组合作用连续梁是一种新型组合梁，采用ABAQUS有限元软件以变参数的方式对其进行了有限元模拟，共开展了10个有限元模型的研究分析，并据此进行试验设计。模型的变化参数包括下部混凝土板的宽度、厚度和长度。分析结果表明：下部混凝土板厚度、长度和宽度均对组合梁刚度影响较大；  对组合梁极限承载力影响较大的参数只有下部混凝土板厚度；  与钢-混凝土单面组合作用连续梁相比，钢-混凝土双面组合作用连续梁在刚度和承载力方面有明显优势，具有较大的工程应用价值。

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
