摘要
以某楼板开大洞高层剪力墙结构为例,采用全弹性楼板模型,计入板的平面内变形,分别按振型分解反应谱法和时程分析法进行整体抗震分析,确定潜在可能的配筋控制单元,求出最大平面内主轴力作为地震作用工况。按夹心单元模型,组合竖向荷载工况后,作为配筋依据。
A high-rise structure with big holes in upper floors building was taken as an example,using elastic slab model and considering in-plane deformation of plate,through performing seismic analysis of whole structure by mode-superposition method and time history analysis method to determine the potential for reinforcement control unit and biggest plane axis force as the working condition of seismic action. In accordance with the sandwich unit model,combing the vertical load condition as the basis of reinforcement.
