摘要:
针对钢框架-混凝土芯筒混合结构的不足，提出了钢框架-屈曲约束支撑-混凝土芯筒多重混合结构形式。根据刚度相等原则，建立了多重钢混凝土混合结构的简化力学模型，给出了框架、支撑钢架和混凝土芯筒的刚度计算公式，根据弹性理论推导出了结构的平衡微分方程，依据边界条件得到了在倒三角水平荷载、均布水平荷载和顶点集中水平荷载作用下侧移和内力的简化算法，最后，对简化算法的可靠性进行了验证。结果表明：该算法具有优良的精度，且应用简便，可供工程设计人员采用。
Abstract:
According to the shortage of steel frame and concrete core canister mixed structure, the steel framebuckling constraint braceconcrete core multilateral resistant mixed structure was put forward. Simplified mechanical model of multi-lateral resistant steel-concrete mixed structure was established based on the stiffness equation principle. Stiffness calculation formulae of frame, brace steel frame and concrete tube were given, and the equilibrium differential equations of the structure were deduced according to the elastic theory. Then the lateral and internal force simplified algorithms were deduced based on boundary conditions under the inverted triangle lateral load, uniformly lateral load and topconcentrated lateral load. Finally, the reliability of the simplified algorithm was verified. The results show that the simplified algorithm has good accuracy, and it is easy for application, and can be applied for the engineering designers.
