  1. The results show that the performances of precast prestressed beam - to - column concrete connections with unbonded tendons are equal or superior to that of a monolithic connection in terms of ductility and displacement - restoring capacity

    結果表明，無粘結預應力裝配式混凝土框架連接具有良好的耗能能力，在延性和變形恢復能力上比現澆連接更優。
  2. Throw the research we can get the performance of the joint of the unbond precast and pretressed continuous beam and how the moment redistributes. we got the conclusion that compare the monolithic prestressed continuous beam, the unbond precast and pretressed continuous beam has short amplitude modulation capacity

    得到預制預應力連續梁接縫處的受力性能，內力重分佈的表現形式，並認為在極限荷載下預制預應力連續梁的調幅能力低於整澆式連續梁等特性。
  3. Precast prestressed concrete beam

    預制預應力混凝土梁
  4. Based on tests of three moment - resisting beam - column connections under low reversed cyclic loading, this paper inquires into the failure pattern, hysteresis loop curves, displacement - restoring capacity, displacement ductility and energy dissipation of the precast prestressed beam - to - column concrete connections with unbonded tendons

    摘要通過三個框架節點在低周反復荷載下的試驗，對無粘結預應力裝配式混凝土框架連接的破壞形態、滯回曲線、變形恢復能力、位移延性、能量耗散等性能進行了研究。
  5. Firstly, the paper sums up program foundation of the auto design system for the structure of prestressed composite slab, in which object - oriented programming and multi - language programming are discussed emphatically. secondly, the paper illustrates program design of the auto design system in preprocess section, analyses calculation section and postprocess section respectively, in which the function design of the intellectualized collocation, the continuous beam model, the check of the precast slab, auto generation of the calculations and shop drawings is described weightily. finally, the practical design methods and process of the structure system of prestressed composite slab are expatiated by representative example

    在綜述了預應力樓蓋體系以及計算機輔助設計的相關內容，分析了國內外研究現狀，研究了疊合樓蓋的受力機理、抗彎抗剪性能以及經濟指標后，文中首先概括了預應力疊合樓蓋體系自動設計系統的編程基礎，其中重點討論了面向對象程序設計和混合語言編程技術；然後分前期處理、分析計算、後期處理三部分，詳細說明了預應力疊合樓蓋體系自動設計系統的程序設計，其中突出描述了程序所特有的智能布置、連續梁模型、預制板校核、生成計算書及施工圖等功能的設計；最後用實例講述了預應力疊合樓蓋體系的實際設計方法及步驟。
  6. The precast and pretressed continuous beam is differente from the monolithic prestressed continuous beam in capability. so there shoule be difference in performance on load. because of little research in this field, i designed and tested three beams which is two - span continuous beams

    由於裝配式預應力混凝土連續梁與通常的整澆式預應力混凝土連續梁的性能有較大的區別，其受力性能也應有所不同，但目前在國內外對此類結構形式還缺乏較為系統的研究。
