The expansion of PT Suri Tani Pemuka’s warehouse complex, known as Banyuwangi Aquafeed, serves as a raw material storage warehouse with a total area of 1.62 hectares. This structure, located in a medium seismic area near the Bali Strait, is designed to withstand seismic activity categorized as risk level II. With a rafter span of 60 meters, it is considered an extreme long-span structure and the dominant factor is its self-weight. Struclab offers solutions for cost-effective design through the use of two design methods: conventional design and pre-engineered building design, with a steel weight ratio not exceeding 25 kg/m2.
