Abstract
Indonesia, located at the convergence of the Australian, Pacific, and Eurasian tectonic plates, is highly susceptible to earthquakes that can damage buildings and infrastructure, including bridges. Many bridges in Indonesia were built without considering earthquake loads based on the 2010 seismic map, necessitating structural upgrades. This research focuses on strengthening the Rawa Buaya Overpass Bridge using Lead Rubber Bearings (LRB) as a base isolation system. This system allows the foundation to move independently during an earthquake, reducing the transfer of forces to the main structure. This study is based on the latest SNI 2833:2016 standards, ensuring that the bridge design meets current seismic requirements. The aim of this study is to enhance the earthquake resistance of the Rawa Buaya Overpass Bridge and provide guidelines for the design and policy of future bridge reinforcements. Analysis of the existing substructure (pier) using a fixed-base approach indicates that pier 7 can only withstand 87% of the ultimate forces (Mu/ΦMn of 114%). LRB type 1 is used to address this limitation, effectively absorbing and dissipating seismic energy, optimally reducing base shear. These findings demonstrate that the use of LRB can improve the seismic performance of the Rawa Buaya Overpass Bridge, making it safer and more reliable. Keywords: Earthquake, Base Isolation System, Lead Rubber Bearings (LRB), SNI 2833:2016, Flyover Rawa Buaya Bridge Indonesia, yang berada di pertemuan lempeng tektonik Australia, Pasifik, dan Eurasia, sangat rentan terhadap gempa bumi yang dapat merusak bangunan dan infrastruktur, termasuk jembatan. Banyak jembatan di Indonesia tidak memperhitungkan beban gempa sesuai peta gempa 2010, sehingga diperlukan peningkatan struktural. Penelitian ini berfokus pada perkuatan Jembatan Simpang Atas Rawa Buaya menggunakan Lead Rubber Bearings (LRB) sebagai sistem isolasi dasar. Sistem ini memungkinkan pondasi bergerak mandiri saat gempa, mengurangi transfer gaya ke struktur utama. Penelitian ini berdasarkan standar SNI 2833:2016, memastikan desain jembatan memenuhi persyaratan ketahanan gempa. Tujuan studi ini adalah meningkatkan ketahanan gempa Jembatan Simpang Atas Rawa Buaya, serta memberikan panduan desain dan kebijakan penguatan jembatan. Analisis struktur bawah (pier) eksisting dengan pendekatan fixed base menunjukkan pier 7 hanya mampu menahan 87% dari gaya-gaya dalam ultimit (Mu/ΦMn sebesar 114%). LRB tipe 1 digunakan untuk mengatasi keterbatasan ini, efektif menyerap dan meredam energi gempa, mengurangi base shear secara optimal. Hasil ini menunjukkan penggunaan LRB dapat meningkatkan kinerja seismik struktur simpang atas Rawa Buaya, menjadikannya lebih aman dan andal.
