(水利部黃委會勘測規(guī)劃設計研究院 鄭州 450003)[提要] 著重介紹了預應力混凝土框架體系在高層建筑中的應用,分析了各種方案的優(yōu)缺點,對預應力框架梁的截面選擇、次彎矩計算、預應力筋確定進行了詳細的分析,為高層建筑采用大跨預應力結(jié)構(gòu)提供了有益的探索。
[關(guān)鍵詞] 高層建筑 大跨 有粘結(jié)預應力混凝土 框架梁 結(jié)構(gòu)布置This article discusses the use of prestressed concrete frame system in high-rise buildings and analyses the advantage and disadvantage of all kinds of plans. In addition, sectional selection, secondary moment calculation and prestressed tendon number decision are also researched. It provides useful probations for making use of prestressed concrete long span structure in high一rise buildings.
Keywords: high-rise buildings; long span; bonded prestressed concrete; frame beam; structure layout
