主厂房采用混凝土单跨框-排架结构的抗震设计措施

讨论了火电厂主厂房框-排架结构采用钢结构还是钢筋混凝土结构体系的条件;分析了主厂房钢筋混凝土框架结构抗震性能的薄弱环节.按照现行国家标准合理判断钢筋混凝土单跨框架条款的有关规定,提出了钢筋混凝土单跨框-排架结构体系在火电厂主厂房能不能采用,如何控制结构的安全度,在工程审查和设计中如何理解和执行上述规定的意见.在总结过去工程设计经验的基础上,提出了提高钢筋混凝土单跨框架结构安全度的可靠措施.

Use of aseismic measures of single span concrete structure of framed bent in main power buildings

This paper discusses conditions of using steel structure or reinforced concrete structure in the structure of framed bent of the main power building in thermal power plants,and analyses weak links of aseismic behaviour of reinforced concrete frame structure in main power building.In view of current national standard,it reasonably judges related regulations of reinforced concrete single span frame structure clauses,and puts forward suggestions that whether the reinforced concrete single span structure of framed bent can be used in main power building of thermal power plants or not,how to control the safety degree of structure,and how to apprehend and implement the suggestions in engineering censorship and design.This paper also gives some measures to improve the safety degree of reinforced concrete single span frame structure based on summarizing the past engineering design experience.
