【摘要】：某電廠封閉式煤場鋼結(jié)構(gòu),跨度200m,長度240m,矢高為42m,為大跨度煤場封閉結(jié)構(gòu)。從單元受力、剖面形狀、荷載、設計參數(shù)、預應力影響等多方面論述了超大跨度結(jié)構(gòu)的設計選型問題,并對結(jié)構(gòu)進行風荷載作用、地震作用、支座位移影響及整體穩(wěn)定性進行了分析,最后提出了超大跨度煤場結(jié)構(gòu)設計中的幾點建議,為超大跨度煤場結(jié)構(gòu)的推廣應用積累了一定的經(jīng)驗。
[Abstract]:The enclosed coal yard steel structure of a power plant has a span of 200m, a length of 240m and a vector height of 42m. it is a large-span closed structure of coal yard. From the aspects of element force, section shape, load, design parameter, influence of prestress and so on, this paper discusses the design and selection of super-span structure, and carries on wind load and earthquake action to the structure. The influence of support displacement and overall stability are analyzed, and some suggestions in the design of super-span coal yard structure are put forward, which have accumulated some experience for the popularization and application of super-span coal yard structure.
