| dc.description.abstract | This study analyzes the seismic performance of regular and irregular building
structures according to the SNI 1726:2019 standards. Four building models were
developed: one regular structure and three irregular structures, using data from the
earthquake-prone Tarutung region in Sumatra. The analysis, conducted with
ETABS software, focused on key seismic parameters including base shear, story
shear, displacement, torsion, and column reinforcement. Results showed that
regular buildings performed better under seismic loads, exhibiting lower base
shear, story shear, and torsion due to their symmetrical configuration and uniform
mass distribution. But the Country is such that where even less than irregular
structures also faced more in seismic force and higher displacement at across the
horizontal direction, torsional effects were seen much stronger especially with
significant irregularities. This resulted in non-uniform distribution of forces and
localized higher requirements for column reinforcement. These results underline
how regular buildings, where developing countries have the most capacity to make
improvements in construction quality and safety on a large scale, are actually quite
resilient structures against seismic forces. This research demonstrates the
significance of complying with seismic design codes and offers perspective which
may assist engineers to develop irregular building structures that are more
earthquake resistant | en_US |
