大型火电厂空间框排架结构非线性有限元研究
Nonlinear finite element analysis of frame-bent structure in one large-scale thermal power plant
【摘要】 对某火电厂主厂房中钢筋混凝土框排架结构进行了非线性Pushover反应分析,研究了该类结构在横向"大震"作用下的薄弱环节、破坏机理、框架与排架结构的协同工作性能等相关内容,可供服役期该类结构的可靠性鉴定及加固参照。
【Abstract】 Nonlinear pushover response analysis of reinforced concrete frame-bent structure in one large-scale thermal power plant is made.The vulnerable parts of this kind of structure under the transverse action of rare earthquake as well as failure mechanism and cooperative action between frame and bent are studied,in order to provide references for reliability assessment and reinforcement treatment during working.
