以抗震设防烈度为9度的某高层建筑结构为实例,基于结构构件间的线刚比概念,从结构计算分析和抗震延性措施两个方面,论述了构件之间的相对“强弱”关系。在抗震概念设计方面,延伸了“强柱弱梁”的含义,扩展了竖向构件“强剪强弯”以及剪力墙连梁“弱连梁不弱”、“强连梁不强”等结构概念。在结构设计分析阶段,应同时注重结构的整体控制与局部协调;强调协同工作是提高结构综合抗震能力的根本;即使结构在遭遇罕遇地震时发生破坏,此破坏也应是一个延性的塑化过程。
Taking a high-rise building with a seismic fortification intensity of 9 degrees as an example, based on the concept of line-to-line ratio between structural members, the relative strength between components is discussed from the aspects of structural calculation and analysis and seismic resistance measures. relationship. In the concept of seismic design, the extension of the “strong column weak beam” meaning, expanding the vertical component “strong shear strength ” and shear wall Strong beam is not strong "and other structural concepts. At the stage of structural design analysis, the overall control and local coordination of the structure should be emphasized simultaneously. It is emphasized that the coordination work is the basis of improving the comprehensive anti-seismic capability of the structure. Even if the structure is destroyed during the rare earthquake, the damage should be a ductile plasticization process.
