Abstract

Indonesia merupakan negara dengan tingkat aktivitas seismik yang tinggi karena terletak pada pertemuan empat lempeng tektonik utama. Oleh karena itu, penerapan sistem struktur tahan gempa menjadi hal yang sangat penting dalam dunia konstruksi. Penelitian ini bertujuan untuk menganalisis pengaruh frekuensi getaran terhadap simpangan antar lantai pada model bangunan tiga lantai dengan dan tanpa dinding, melalui uji eksperimental menggunakan meja getar. Dua model bangunan skala 1:20 dibuat: model X tanpa dinding dan model Z dengan dinding pada lantai 2 dan 3. Pengujian dilakukan dengan variasi frekuensi yang meningkat bertahap untuk mengetahui perubahan respons struktur terhadap getaran. Hasil penelitian menunjukkan bahwa semakin tinggi frekuensi yang dikenakan, semakin besar simpangan antar lantai yang terjadi. Pada frekuensi dan percepatan yang sama, model Z mengalami simpangan yang lebih kecil dibandingkan model X, yang menandakan bahwa keberadaan dinding membantu mengurangi perpindahan lateral. Kedua model mengalami keruntuhan pada percepatan keempat dengan frekuensi getar 3,251 Hz, menunjukkan bahwa dinding mampu menunda keruntuhan, namun tidak sepenuhnya mencegahnya. / Indonesia is a country with high seismic activity due to its location at the convergence of four major tectonic plates. Therefore, the implementation of earthquake-resistant structural systems is crucial in the field of construction. This study aims to analyze the effect of vibration frequency on inter-story displacement in a three-story building model, both with and without walls, through experimental testing using a shaking table. Two 1:20 scale building models were constructed: model X without walls and model Z with walls on the second and third floors. The tests were conducted with gradually increasing frequency variations to observe changes in the structural response to vibrations. The results show that higher applied frequencies lead to greater inter-story displacements. At the same frequency and acceleration, model Z experienced smaller displacements compared to model X, indicating that the presence of walls helps reduce lateral movement. Both models collapsed at the fourth acceleration level with a vibration frequency of 3.251 Hz, indicating that while walls can delay collapse, they cannot completely prevent it.
