高耸结构静力弹塑性分析研究
|
摘要
以改建的钢筋混凝土高耸结构——原南市发电厂烟囱作为研究对象,以上海2010年世博会观光塔这一典型的钢筋混凝土筒体结构作为背景工程,通过采用Pushover分析方法对其进行了全面地震作用下的静力弹塑性分析,计算结构在不同地震作用下的地震效应,研究结构在相应地震作用下的抗震性能,并分析结构在加固前后抗震性能指标的变化,明确结构的薄弱位置,为结构的加固设计提供理论依据。同时,也为类似改建工程的结构分析及设计提供借鉴。
This paper is based on a practical project—the Harmony Tower for 2010 Shanghai World Expo,which is a typical R.C.shear-wall tube structure.The paper presents a thorough pushover analysis for the structure,hoping to provide useful advice for the project design and future pushover analysis for shear wall structural system.
