(北京邁達斯技術(shù)有限公司，北京100044)[摘要] 本文介紹了初始荷載的選擇對Pushover分析的影響。指出在不同的初始荷載工況下，Pushover分析的塑性鉸結(jié)果發(fā)生的順序和位置都有所不同，從而影響結(jié)構(gòu)在強震下的評估判斷。在MIDAS Gen中，以一個框筒結(jié)構(gòu)簡單算例，表明采用施工階段分析最終階段結(jié)果更為接近實際的初始荷載的施加，使Pushover的分析結(jié)果更加合理。

( Beijing MIDAS Information Technology Co., Ltd., Beijing 100044, China)Abstract: The influence of initial load to the Pushover analysis was introduced, and points out that under different initial load cases, the location and order of plastic hinges of Pushover analysis are different, and it is proved in a case of frame tube structure that the construction stage analysis process is more closer to the actual initial load, and it makes the Pushover analysis results more reasonable.
Keywords: MIDAS Gen; construction stage; Pushover analysis; initialload
