摘　　要：为尽量减小建筑结构高度从而增加建筑室内净高,结合工程应用提出一种部分埋入式钢-混凝土组合梁,以改善钢梁受压翼缘整体稳定性、增加钢梁与混凝土板的共同工作能力。对部分埋入式钢-混凝土组合梁进行有限元分析,研究埋置深度、钢筋配筋率、型钢强度等级和混凝土强度等级等参数与其截面受力性能的关系。研究结果表明:型钢强度越高、混凝土强度越高、钢筋配筋率越大,部分埋入式钢-混凝土组合梁的受力性能越好;埋置深度越大,部分埋入式钢-混凝土组合梁受力性能越差。To minimize the height of the building structure and increase its interior net storey height,a partially embedded steel-concrete composite beam is proposed combing with engineering application,and the overall stability of the compression steel beam flange is improved,and the cooperation ability of steel beam and concrete slab is increased.The partially embedded steel-concrete composite beam is analyzed using the finite element.The relationship between the beam parameters and the mechanical performance on its section is studied,which include embedded depth,steel ratio,section steel strength grade and concrete strength grade.The results show that the mechanical performance of partially embedded steel-concrete composite beam is better while the strength of the profile steel is higher,the strength of the concrete is higher,and the reinforcement ratio is greater;the greater the embedded depth,the worse the mechanical performance of partially embedded steel-concrete composite beam.
