| Abstract | ||||
| The present study is aiming to evaluate the seismic performance of moment resisting steel frames with partial rigid connections considering elasto-plastic behavior of girder to column connection under the effect of earthquake loadings. The frame performance prediction and evaluation procedure are mainly based on the nonlinear dynamic analysis considering both geometrical and material nonlinearities. The current paper investigates the effects produced by some earthquake records on steel moment resisting frames considering both SDOF (SINGLE DEGREE OF FRADOM) system and MDOF (MULTI DEGREE OF FRADOM) system. Statistical analyses are performed to characterize the response of such frames by obtaining comparable results that allow the determination of the behaviour factor for each frame (Q- factor) which expresses the degree of damage for each frame. The results summarized in terms of base shear-top displacement relationships considering different earthquake records and at P.G.A. (Peak Ground Acceleration) level 0.35G (0.35 from ground acceleration levels). Finally the values of the Q-factor for each frame and the comparison of such values with respect to the current seismic provisions were outlined. | ||||
