【摘要】 以改建的钢筋混凝土高耸结构——原南市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工程背景,介绍改建加固的结构方案以及结构改造的内容,详细说明结构改建加固设计的做法,并计算分析加固前、后结构的主要计算指标,验算并对比结构改建前后的承载能力极限状态及正常使用状态下的各个指标,并就指标进行分析,比较结构改造加固的效果。更多还原

【Abstract】 Based on reconstructing the RC chimney of the former Nanshi Electric Power Plant,which is a typical RC tube structure,into a sightseeing tower for 2010 Shanghai World Expo,it is presented the structural reinforcement scheme and reform contents,and it is described in detail the design of reinforcement and reform of the stucture.It is calculated the main indexes of the structure before and after the reinforcement.It is also checked and compared the indexes of the bearing capacity at ultimate state and normal service state for the structure before and after the reinforcement,through which the reinforcement effect was analyzed.更多还原
