<![CDATA[The inter-story drift occurs as the result of rotational deformation on the frame’s joint affected by ground shaking. This rotational deformation occurs as an accumulation of bending deformation in beams and columns as well as shear deformation in the panel zone. The goal of this study is to analyze how cyclic non-linear deformation occurs in beam elements and zone panels. The 8-story steel moment resisting frame built on class D soil and designed for seismic design category D were used as model. Incremental nonlinear dynamic analysis was carried out using 20 earthquake ground motions that contained with and without pulse effects. This was done so in order to identify the median value and standard of deviation of the LS, CP, and collapse boundary conditions. Nonlinear flexure and shear deformations that occur in beam element and panel zone were explored. The results obtained show that the rotational deformation of the beam due to actual flexure is greater when compared to the rotational deformation at IDRmax reaches the first time LS and CP boundary conditions. The similar trend occurs in shear deformation of the panel zone.]]>
