Abstract
In dynamic analysis, the vibration period of a structure is recognized as a crucial factor that determines the structural response to earthquakes. The value of the structural vibration period is closely related to the stiffness and mass of a building, both of which are associated with the height and number of floors in the building. This study aims to establish a relationship between the structural vibration period, building height, and the number of floors in Indonesia. This research employs eigenvalue calculations to determine the structural vibration period. The vibration periods of 27 buildings with varying heights and numbers of floors are calculated, followed by statistical analysis to derive an empirical formula for the structural vibration period. The research findings indicate that the obtained vibration period data and resulting equation fall within the range of previous studies that employed direct measurement methods. Furthermore, this study proposes empirical formulas for the structural vibration period developed based on the lower bound of this research's data, offering estimates of conservative design earthquake forces.
Keywords: Vibration period, building height, number of floors, moment-resisting frame, concrete
Abstrak
Di dalam analisis dinamis, periode getar struktur diketahui menjadi faktor penting yang menentukan perilaku struktur terhadap gempa. Nilai periode getar struktur erat kaitannya dengan kekakuan dan massa bangunan, dimana keduanya berhubungan dengan tinggi dan jumlah lantai bangunan. Penelitian ini bertujuan mencari hubungan antara periode getar struktur dengan tinggi dan jumlah lantai bangunan di Indonesia. Penelitian ini menggunakan perhitungan nilai eigen untuk mendapatkan periode getar struktur. Sebanyak 27 bangunan gedung dengan ketinggian dan jumlah lantai yang bervariasi dihitung periode getarnya. Selanjutnya dilakukan analisis statistik untuk mendapatkan rumus empirik periode getar struktur. Hasil penelitian menunjukan bahwa data nilai periode getar dan persamaan yang dihasilkan berada dalam rentang data penelitian sebelumnya yang menggunakan metode pengukuran langsung. Selain itu, penelitian ini mengusulkan rumus empirik periode getar struktur yang dikembangkan berdasarkan batas bawah dari data penelitian ini untuk memberikan perkiraan gaya gempa desain yang konservatif.
Kata-kata kunci: Periode getar, tinggi bangunan, jumlah lantai, rangk a pem ik ul m om en, beton.
