  3. This paper, in allusion to damage of expansion joint of bridge, introduces a sort of new structure of jointless device - semi - integral abutment jointless bridge, and establishes model of general structure finite element of this bridge, and in details analyses its qualities of stress. the model considers the interaction of superstructure - substructure - soil. resistance of the soil behind abutment adopts still soil pressure and elastic resistance when the temperature rising, but active soil pressure when dropping. analysis of qualities stress of bridge includes of action of dead load, car load, temperature load of season character. taking an 100m length pc semi - integral abutment jointless bridge as instance, the paper establishes the model of plane frame by applying large common software - anasys, and analyses it by elastane and large deformation to imitate character of stress and deformation of general bridge. at the same time corresponding models of finite element of joint bridge and integral abutment bridge are established, and unique stress and performance of structure of semi - integral abutment jointless bridge are researched by comparing and analysing character of three different models under same loading, and controlling factor of design and constitution are generalized. in conclusion, for semi - integral abutment jointless bridge, on one hand shear, moment and deflection of the main beam and axis force of substructure are approximate with that of joint bridge, and integral stifmess of structure is increased and damage of expansion joint is eliminated, on the other hand there is axis force in main beam, shear and moment of substructure are bigger than that of joint bridge. in all this type of jointless bridge has rational stress and is worth of application and popularization

    半整體式橋臺無縫橋梁計算模型考慮了上部結構-下部結構-土的共同作用；臺後土抗力升溫時採用靜止土壓力加彈性土抗力，降溫時採用主動土壓力；分析橋梁受力性能時考慮了結構自重、車輛荷載和季節性溫變荷載的作用。以一座橋長100mpc半整體式橋臺無縫橋梁為實例，採用大型通用軟體ansys建立平面框架模型，進行彈性、大變形分析，模擬全橋受力和變形特點；同時建立與此對應的有伸縮縫橋梁和整體式橋臺無縫橋梁有限元模型，通過三種橋型同步加載對比分析，研究半整體式橋臺無縫橋梁獨特的受力特點和結構性能，總結其設計控制因素和構造要求。通過本文研究知：半整體式橋臺無縫橋梁主梁的剪力、彎矩、撓度和下部結構的軸力與梁式橋相近，結構整體剛度增大，併除去了伸縮縫病害；但主梁增加了軸力，下部結構剪力、彎矩較梁式橋大；綜合分析是一種受力合理有實踐和推廣價值的橋型。
  4. Using the style for defining smart material structure brought forth in the field of aerospace industry for reference, the author gives the definition to ics / ibs explicitly, that is : " because of partially embedded intelligent substructure or intelligent material, the civil / bridge structures are endued with animal - imitated function such as self - monitoring, self - diagnosis, self - adaptation and self - restoration, and as a result, the demand of structure safety and service convenience are met in maximum degree. these structures are called after the intelligent civil / bridge structure, in short, ics / ibs ". meanwhile, a classification for ics / ibs is made, and the main development direction for research - embeded ics / ibs is pointed out as well

    本文借鑒首先由航空航天製造業提出的智能材料結構概念的定義方式，明確地提出了智能土木結構的概念及定義，即： 「土木（橋梁）結構中因嵌入部分智能子結構或智能材料，使其具有自監測、自診斷、自適應或自修復等仿生功能，從而能極大地滿足人們在結構安全性及使用維護方便性等方面的要求，這種土木結構就稱為智能土木（橋梁）結構」 。
