西安理工大学硕士学位论文T-tIe：THE 西安理工大学硕士学位论文 T-tIe：THE OPTIMUM RESEARCH OF BEAM-COLUMN-JOINCONNECT -ION OF THE STEEL STRUCTURE Major：Structure Engineering Name：Fen WANG sjgn砒u暇盈毖： Supervisor：Prof．Duixian GAO signature：g生!!=：垒 Along with the steady development of the economy,the steel structures being applied extensively Bocaugc of the SpeCis]function．During the 1994 Northridgn earthquake and 1995 Kobe earthquake，as well the troubles of the steel structures that appear in the process of construction．T§e typical beam-column nmment connection in steel moment-resisting缸mB suffered unexpected brittle failures．many studies the behavior of beam-column connections used in steel moment resisting flanle and their effect 0n seismic behaviOr of steel frames have been carried OuL The beam-column connection of the steel frame structure usually being used with the rigid connection design in which there is enough rigid in the connection ofmain beam-column．According to the conjunction method,the steel structure beam-column conjunction be divided into：weld conjunction，the bolt connection node and bolt-weld connection． Firstly,inthisthesis,bymeansofdesignpointofview,thecompleteanalysis and studyhadbccndone about the three kinds of main rigid connection design．Point out the problem which consist in the designs of beam-column connection of the steel flame structure．Put forward the correct design methods about beam-column connection． Secondly,it had been elaborated in detail the design thought of improving steel tame be㈣lumn joints by making of the dog-bone connection．A great deal of operation had been carried by ANSYS procedure in order to contrast and analyze the function of undertaking various power A conclusion had been draw out：when dog—bone connection had been adopted，if the size of beam edge being weaken adequately, the stress biggest value of beam-column connection under power will appear at the part which had been weaken beam edge where there is great deal of transform
