| Research Abstract |
This paper performs the earthquake response analysis of two-storey steel portal frames. The shear buckling behaviour of web plates in the middle of the 1st storey beam is paid attention to by the substructure pseudodynamic testing method. The numerical results illustrate the non-linear response of frames including the remarkable change in shearing resistance force of web plates due to buckling and diagonal tension-field. The damage mechanism of frames is discussed by focusing on whether or not the shearing collapse of web plates in the 1st storey beam could save the damage of another structural parts.
