Abstract

Engineers are often interested in creating structures with unique and innovative architecture. One of the challenges in making these structures is the difficulty in using specific materials and achieving the desired shape. In this research, large-scale structures were built using Miura's origami pattern, high and ultra-high-performance canvas concrete, and ultra-high-performance fiber-reinforced concrete to solve these challenges. The performance of structures under flexural load was evaluated. Three non-sandwich structures and one sandwich structure were built. Non-sandwich structures were made using high-performance canvas concrete, ultra-high-performance fiber-reinforced concrete (UHPFRC), and ultra-high-performance canvas concrete. Using the Miura pattern in these specimens enhanced the load capacity of the structures by 2.5 to 4.3 times in the same conditions. Also, the behavior of a sandwich structure with an origami core was made with high-performance canvas concrete and upper and lower plates with UHPFRC was investigated, which showed an increase of 4 and 9.8 times the load capacity compared to non-sandwich structures.
