Abstract

Penelitian ini difokuskan untuk mengkaji sejauh mana penggunaan material ringan dan fleksibel dapat
mengurangi gaya inersia pada struktur gedung sekolah berlantai dua di kota Banda Aceh, serta
menganalisis pengaruhnya terhadap perilaku dinamis struktur saat terjadi gempa, ditinjau dari aspek
deformasi, percepatan lantai, dan gaya geser dasar. Dengan memahami hubungan ini, diharapkan dapat
diperoleh rekomendasi desain yang lebih efektif dalam pembangunan gedung tahan gempa. Dengan
membandingkan jenis material struktur (konvensional Model A vs. ringan/fleksibel Model B) dan
respons struktur terhadap gempa, yaitu deformasi maksimum (displacement), percepatan puncak lantai
(peak floor acceleration) dan daya geser dasar (base shear). Akhir dari kajian ditemukan bahwa Model
B memiliki periode lebih panjang, artinya lebih lentur ? cocok untuk redam gempa frekuensi tinggi.
Gaya geser dasar lebih kecil karena massa bangunan jauh lebih ringan. Perpindahan puncak lebih besar
(normal untuk struktur fleksibel) tapi masih dalam batas aman. Drift antar lantai pada Model B masih
di bawah batas SNI (? 2%).
