  1. Ultimate stress increment is a hotspot problem in theory of unbonded partially prestressed concrete structure, however, according to design critera and the art of the state on this issue around the world, it is still not considered in reason that ultimate stress of unbonded tendons in prestressed concrete multi - span continuous structures varies with load cases

    無粘結筋的極限應力增量一直是無粘結預應力混凝土結構理論中熱點問題，而從目前各國的設計依據及研究現狀來看，還沒有合理考慮多跨連續結構的無粘結筋極限應力隨荷載工況變化的情況。
  2. Secondly, the producing mechanism of crack in reinforced structure and factors which affect crack have been discussed, in the emphasis, the method is expounded, which applies first releasing then resisting, combination of releasing and resisting. in the method, flexible slit is applied firstly, which can make deformation of structure distributed, and decrease deformation energy, then the tiny expansion concrete and prestressed concrete with unbonded tendons are applied. and in the different phase, the compressive prestress is put on the concrete structure

    其次，分析並論述了鋼筋混凝土結構裂縫產生的機理和影響因素，著重闡述了「利用先放后抗，抗放結合，綜合控制」的方法：即首先利用后澆帶，使混凝土結構分段變形，減小超長變形的影響；並採用微膨脹混凝土技術及無粘結預應力混凝土技術，分階段對混凝土結構施加一定的預壓應力，從而減小或完全抵消混凝土結構因混凝土硬化收縮引起的拉應力；再結合一些其他措施，成功實現鋼筋混凝土結構的超長無縫設計與施工。
  3. Unbonded prestressed concrete structure

    無粘結預應力混凝土結構25
  4. The development of the technology of the prestressed concrete with unbonded tendons has promoted the development of new materials, new structure, new technology, new craftwork. since 1980 the application has ranged from single member to a whole structure such as flat floor, frame, high - story structure, portal rigid frame, special structure and special structure

    無粘結預應力混凝土技術的發展，促進了新材料、新結構、新技術、新工藝的發展，自80年代以來，已從單個預應力混凝土構件發展到預應力混凝土結構：平板結構、框架結構、門式剛架、高層結構、空間結構及特種結構等。
  5. At the same time, it brings the greater displacement reaction, lower energy - dissipation capacity and badly ductility ability etc. the unbonded partially prestressed concrete flat - beam frame structure has been used in the practice project in our country, but the aseismatic study of this structure is not perfect at present, study on theory is lagged behind the demand of engineering apply. it has important theoretic meaning and applied value to go deep into the examinational study about the prestressed concrete flat - beam frame structures

    近年來國內已經開始在實際工程中採用無粘結部分預應力混凝土扁梁框架結構，但是目前對這種結構形式的抗震研究工作還不完善，理論研究已滯後於工程應用的需要，因此深入進行扁梁框架結構的研究，在經濟合理的情況下確保該結構的抗震安全性具有重要的理論意義和應用價值。
