摘　　要：结合某工程的转换结构 ,对三种设计方案的内力幅值、地震作用下的侧移曲线以及转换结构层刚度比进行了比较 ,结果表明 ,格构式钢骨混凝土结构有较多的优点。重点阐述了钢骨混凝土构件的粘结强度设计、裂缝宽度验算。为保证节点的工作性能 ,采取了梁端加腋和设置节点加强桁架的构造措施 ,并提出了格构式钢骨混凝土节点受剪强度计算公式及转动刚度分析方法。Three design schemes for the transfer structure in one building are introduced and the maximum value of interior force,seismic behavior and level stiffness ratio are compared.The results indicate the lattice SRC structure's behavior is good as a whole.It especially presents the calculation method for bond strength and crack width of SRC beams and SRC columns.In order to satisfy working performance of joints,the haunched beam and the reinforced truss at joints are applied properly,and the formula for shear strength and the analysis of rotational stiffness are presented.
