火力发电厂混凝土结构主厂房中,对汽机房与煤仓间(或除氧间)联合的框排架结构体系,若认为是单框架结构,在项目设计和审查时往往受到《建筑抗震设计规范》的设计限制.事实上,此类结构为单跨框-排架结构体系,不能按照单框架结构来进行设计.在动力弹塑性分析的基础上,结合工程实践和相关规范的修订精神,编制了《火力发电厂主厂房混凝土单跨框-排架结构体系选型设计指南》,可供具体工程设计参考.
In the main plant of the thermal power plant concrete structure, if the frame frame structure system combined with the steam turbine room and the coal bin (or the oxygen scavenge room) is considered as a single frame structure, it is often subjected to the Code for Design of Seismic Design of Buildings “In fact, this type of structure is a single-span frame - frame structure system, can not be designed in accordance with a single frame structure.Based on the dynamic elastoplastic analysis, combined with engineering practice and revision of relevant norms, preparation The ”thermal power plant main plant concrete single-span frame - rack structure selection system design guide" for specific engineering design reference.
