摘    要:提出了预应力混凝土超静定结构的一种新的设计方法──单位次弯矩法,该法以预应力混凝土结构中所有预应力混凝土构件同时满足两类极限状态为设计原则,基本上避免了工程设计中常见的试算过程,并使得设计结果合理,经济;在此基础上,还对如何有效地利用预应力混凝土超静定结构中由于施加产生的次内力进行了详细的研究,并对预应力筋的布置方案,曲线选型,和积极利用非吻合束等问题提出了可供实践应用的设计建议,附有工程设计实例

关 键 词:预应力混凝土  超静定结构  结构力学

Abstract:The unit secondary moment method,a new design method of statically indeterminateprestressed concrete(PC)structures,is introduced. On the principle of all PC members in PCstructures must simultaneously satisfy two categories of limit state ,this method greatly simplifies designprocess and makes design results reasonable and economital,In addition,the problem atout how toefficiently utilize the secondary moment due to prestressing is studied in detail,and the practical designsuggestions about arrangement and curve of tendons are also proposed.A practical design example is illustrated .
Keywords:prestressed concrete  statically indeterminate structures  design/secondary internal force  unit secondary moment
