摘　　要：文章以抚顺某项目11栋高层建筑为例,利用YJKFea软件调整模型结构布置、修改地震相关参数并不断试算,多个模型进行对比,针对楼高百米的长周期剪力墙结构,筛选出影响最小水平地震剪力最大的三个因素为结构刚度、质量参与系数、周期折减系数。用计算数据证明,在中、低烈度地区,其他设计指标满足的情况下,进行地震力调整是最经济实用的方法。Taking 11 high-rise buildings of a project in Fushun as an example, this paper uses YJKFea software to adjust the structural layout of the model, modify the earthquake-related parameters, and compare several models. Aiming at the long-period shear wall structure with a height of 100 meters, Three factors that have the greatest influence on the minimum horizontal seismic shear force are selected: structural stiffness. mass participation coefficient and periodic reduction coefficient. It is proved by the calculated data that seismic force adjustment is the most economical and practical method when other design indexes are satisfied in medium and low intensity areas.
