本文根据不同周期的结构3000多个地震反应的算例,讨论了下列几个问题: 1.地震时结构楼层最大弹塑性变位与结构楼层屈服强度的关系; 2.控制结构变位防止结构倒塌问题; 3.地震荷载沿结构高度分布与场地和结构周期的关系; 4.结构等效质量系数与场地和结构周期的关系。 This paper discusses the following problems based on the examples of more than 3,000 earthquake responses with different periodic structures: 1. The relationship between the maximum elastic-plastic displacement of the structural floor and the floor strength of the structural floor during earthquake; 2. The control structure displacement prevents the structure from collapsing Problems; 3. The relationship between the distribution of seismic load along the height of the structure and the period of the site and structure; 4. The relationship between the structural equivalent quality coefficient and the site and structure cycle.
