| dc.description.abstract | Based on performance-based design, pushover analysis is used to
forecast how buildings will behave during earthquakes. The approach is
to gradually apply a pattern of static lateral loads on the structure until
it reaches its target displacement. The analysis's findings take the form of
base shear-roof displacement curves, which are then utilized to determine
structural performance levels and performance points based on ATC-40,
1996.
In this study, office buildings in Padang City were modeled using
pushover analysis to determine the structural capacity curve, structural
performance level, as well as plastic hinge mechanism that occurs against
MCER-level seismic loads. This pushover analysis was performed using
SAP2000 v22 software under the provisions of ATC-40, 1996.
The results of the pushover analyze against the MCER level earthquake
load were displacement values of 0.369742 m with a base force value of
21392.101 kN for the x direction and 0.365115 m with a base force value
of 32408.387 kN for the y direction. The x direction performance point
values are V = 20149.839 kN and δ = 0.309 m, whereas the Y direction
performance point values are V = 26643.81 kN and δ = 0.231 m.
According to the analysis, the structure's performance level under MCER
seismic load was Damage Control | en_US |
