Studying Frame-Resistant Steel Structures under near Field Ground Motion
This paper presents the influence of the vertical
seismic component on the non-linear dynamics analysis of three
different structures. The subject structures were analyzed and
designed according to recent codes. This paper considers three types
of buildings: 5-, 10-, and 15-story buildings. The non-linear dynamics
analysis of the structures with assuming elastic-perfectly-plastic
behavior was performed using RAM PERFORM-3D software; the
horizontal component was taken into consideration with and without
the incorporation of the corresponding vertical component. Dynamic
responses obtained for the horizontal component acting alone were
compared with those obtained from the simultaneous application of
both seismic components. The results show that the effect of the
vertical component of ground motion may increase the axial load
significantly in the interior columns and, consequently, the stories.
The plastic mechanisms would be changed. The P-Delta effect is
expected to increase. The punching base plate shear of the columns
should be considered. Moreover, the vertical component increases the
input energy when the structures exhibit inelastic behavior and are
taller.
