为探究框架-核心筒混合结构竖向构件受力的规律,通过选取结构刚度特征值λ和核心筒高宽比H/b为参数,建立型钢混凝土框架-钢筋混凝土筒体混合结构非线性参数化模型。采用静力非线性分析方法,对高烈度区SRC框架-RC筒体混合结构竖向构件受力性能进行研究,主要包括混合结构剪力墙墙肢和SRC框架柱截面弯矩、剪力轴力等内力状态及其变化趋势、破坏轨迹等,同时对混合结构竖向构件设计以及截面轴压比限值提出了建议。 In order to explore the regularity of the force of the vertical member in the core-tube hybrid structure, the nonlinear parameterization of the hybrid structure of the SRC-RC structure was established by selecting the structural stiffness eigenvalue λ and the core tube aspect ratio H / b as parameters model. The static nonlinear analysis method is used to study the mechanical behaviors of SRC frame-RC hybrid structure vertical members in high intensity zone, including the bending moment of shear wall and SRC frame column, Such as the internal force status and its changing trend, the trajectory of destruction, etc., And put forward the suggestion to the vertical structure design of the hybrid structure and the axial compression ratio of the section.
