摘要
为合理评估钢框架体型收进结构地震损伤,设计3个九层钢框架顶层不同收进模型,并分析对同一地震波作用下的塑性应变反应,利用Python语言快速提取损伤数据.探究结构关键层构件累积塑性分布,通过对体型收进结构地震作用下的损伤指标进行损伤评估.研究表明:地震作用下,顶层收进会改变结构楼层整体损伤,收进面积越大“鞭梢效应”越明显.
For reasonable seismic damage evaluation in steel frame retractable structure,three nine-floor steel frame models with different top retractions are designed,and the plastic strain response under the same action of seismic wave is analyzed,using the Python language fast extracting damage data.The cumulative plastic distribution of structural key-storey members is explored and the damage index under earthquake action of the body-shaped retracted structure is evaluated.Research shows that:under the action of earthquake,the top floor in will change the structure of the whole floor damage,and the larger the retracted area,the more obvious the“whipping effect”.
