The stadium is a combination of steel reinforced concrete (SRC) columns and a steel roof. DAIZO detailed the pillars in Tekla Structures to ensure constructability of the stadium’s steel frame. Due to their complexity, the pillars were difficult for the manufacturer to produce, making accuracy incredibly important. In addition to its location in a high-seismic area, the stadium’s biggest design challenges include complex ‘Y’ shaped exterior pillars. Overcoming Complex Design Challenges with Constructible BIMĪ 1,300-ton structure, the Saga Natatorium will have the capacity for 1,800 people and will include an Olympic-sized pool, diving pool and sub-pool, along with diving platforms.
“It’s extremely detailed and very demanding compared to other styles, but this is the design challenge that makes our work so interesting.” “I like the Japanese style of design and production of steel structures,” said Li. Today, the company employs 40 people in both countries and has completed more than 100 projects in Japan, as well as 30 projects in Canada and the U.S. Li set up DAIZO in 2015, first opening an office in China and then another in Japan. After graduating, he began working for a structural design company in Nagasaki and began using Trimble’s BIM software, Tekla Structures, to create steel designs. When the region of Saga kicked off plans to build a swimming stadium for the 2024 Japan Games, DAIZO Engineering was tasked with designing the stadium’s steel frame.ĭaizo’s founder and managing director, Hongbin Li moved from China to Japan in 2009 to pursue a master’s degree in Engineering from Kyushu University. As a highly ductile material, steel can flex and deform to dissipate the seismic energy of an earthquake and compared to other building materials, has a higher strength-to-weight ratio. The country experiences approximately 1,500 earthquakes each year, driving the need for seismic resistant building design and construction.Īpproximately 25 million tons of steel is used for construction in Japan every year. From the Great Kanto earthquake in 1923 to the Great East Japan earthquake in 2011, Japan has endured the devastating effects of natural disasters time and time again. Japan sits in the Pacific Ring of Fire, where several continental and oceanic plates meet, making it highly susceptible to earthquakes and tidal waves.
