Pengaruh Perbedaan Nilai Aspek Rasio Horizontal Terhadap Kestabilan Struktur

---

ABSTRACT
The behavior of a building during an earthquake is highly dependent on several
parameters such as shape, size, and overall geometry. These parameters will
determine the overall capacity of the building, especially seismic parameters. The
ratio of vertical aspect (H/L or H/B) and aspect ratio horizontal ratio (L max /L
min) affects the efficiency and stability of the structure in withstanding lateral loads.
This study aims to analyze the influence of variations in horizontal ratio aspects on
the dynamic behavior and stability of reinforced concrete structures. Six models of
three-story building structures with different span configurations (4x4, 5x4, 6x4,
7x4, 8x4, 9x4 spans) were modeled using ETABS. The analysis was carried out
comprehensively through a spectrum response for elastic behavior, with reference
to SNI 1726:2019 for the Pekanbaru earthquake area. The results revealed that the
increase in the aspect ratio of the horizontal ratio significantly affected the dynamic
characteristics of the structure. The results of the study revealed that the increase
in the aspect ratio of the horizontal ratio led to a significant change in the response
characteristics of the structure. The natural period of the Y direction increased from
0.839 seconds to 0.864 seconds, while the rotation mode period experienced the
most significant increase of 9.4%, indicating an increase in torsional susceptibility.
The deviation between the Y-direction floors exceeded the drift limit of 38.462 mm
on Models 3 to 6 with a maximum value of 39.428 mm, while the X-direction
response showed a decrease in displacement of 2.3%. Rolling moment analysis
showed a consistent increase of 113% from Model 1 to Model 6, confirming a linear
correlation with the increase in structure mass. The conclusions of the study
emphasize the importance of considering the aspect of horizontal ratios in
structural planning, especially related to rigidity distribution and dynamic response
for safer and more efficient structure design.
Keywords: Horizontal Ratio Aspects, Dynamic Behavior, Structural Stability,
Reinforced Concrete, ETABS.
