【摘要】 旨在解决大型火力发电厂主厂房钢筋混凝土结构的温度作用问题,在综述已有温度作用分析方法的基础上,提出了温度作用分析的"弹性分析标准结构对比法",对8种结构形式进行了弹性分析对比.其中"底层内置2条单柱伸缩缝"的方案,在不增加投资、不改变结构外形的前提下,巧妙地解决了百万机组主厂房采用钢筋混凝土结构时的温度作用问题.更多还原

【Abstract】 The temperature effect problem of RC main power-house of large thermal power plant is discussed;and an elasticity comparative analysis method is proposed.The length of 1 000MW power unit main power-house is about 100m;and no temperature seam is allowed by process,what make it difficult to design a RC main power-house due to temperature effect.The principle of analysis method for ultralong concrete frames is discussed;and different kinds of structure scheme are compared.The inside temperature joint at the lower floor is recommended for the ultra-long RC main power-houre.更多还原
