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

From above analysis, the thesis gets conclusions as following : ( 1 ) the frequencies of multi - tower building are so dense and the coupling in each mode is so evident that the cqc method instead of srss should be used to calculate the seismic action effect ; ( 2 ) torsion effects is distinct between the modes of asymmetry multi - tower structure and it is necessary to take translation - torsion coupling into account ; ( 3 ) the effect of the enlarged base rigid on the seismic properties is very big, the rigid ratio of the enlarged base to towers in asymmetry multi - tower structure should be designed in a proper range ; ( 4 ) the distribution of plane rigid is asymmetry because of the asymmetry layout of towers. the torsion effects of structure not only result in large torsion internal force in vertical element resisting lateral displacement, but also make large influences on the stress of transfer plate and near floors, thus it is necessary to strengthen those floors
