The national science and technology award conference for 2020 was held at the Great Hall of the People in Beijing on Nov 3. Preliminary statistics show that 38 scientific and technological achievements in Zhejiang province were awarded the second prize and above of the National Science and Technology Awards of 2020. The total number of awards in Zhejiang province has increased significantly, reaching a record high.

 

The project of "system innovation, key technology and engineering application of modern spatial structure" by Professor Luo Yaozhi’s team of School of architectural engineering of Zhejiang University, won the first prize of National Science and Technology Progress Award. "The atmosphere at the conference was very warm. Communicating with the craft brothers, I deeply feel the rapid progress of China's science and technology, and the firm determination in-depth basic research" Luo Yaozhi said in an interview with Zhejiang Daily reporters.

The Expo Axis of Shanghai World Expo, the big lotus of Hangzhou Olympic Sports Center, and the reflector back frame of China Tianyan FAST... These magnificent landmark buildings and projects have a common feature, that is a modern spatial structure characterized by large span, large space, and large area.

 

During the interview with reporters, Luo recalled that in the early 1990s, he and his team constructed the roof structure design of the T1 terminal of Shenzhen Bao'an International Airport, the first terminal in China to use a spatial grid structure at that time.

 

"The terminal has 4000 square meters. With such a large space and only a few columns in the middle, whether it can be used safely is the difficulty in relevant international fields," he said.

 

After receiving this task, Luo and his team usually went to Shenzhen. It is not only to communicate with the construction party about what to make and what structure to use but also to pay attention to whether the processing and construction effects are consistent with the design. Finally, the terminal was successfully completed, which became one of the benchmarks in the field of spatial structure in China at that time.

 

In Luo's laboratory, research on the structure and function of the rotary opening and closing roof and free-form surface of the tennis hall of Hangzhou Asian Games has been carried out and widely used in various projects for several years. For example, the "big lotus" of Hangzhou Olympic Sports Center is curved and twisted. How to design and process it? Luo led the team to develop high-precision processing and manufacturing technology for complex special-shaped components. It formed a complete set of high-precision and efficient processing technology. Luo and his team contributed a beautiful urban landscape to Hangzhou.

Innovative system of modern spatial structure

 

In 2007, Cao'e River Sluice needs to be designed. The plane stress system of beam slab structure is more popular in the academic circle. Luo's team skillfully used the modern space structure system to design the fish-like double arch spatial structure gate.

 

The steel consumption of the gate and electromechanical equipment can save a lot of costs by using this innovative design. The problems of tidal bore and sediment deposition can also be solved. Later, this pioneering project won the first prize in the provincial science and technology progress award.

 

Generally, the test of spatial structure system should adopt the same model as the reality. After the test, the corresponding device will be scrapped. In view of this situation, the team pioneered the spherical omni-directional loading device and made a "general template". It can meet the test requirements of all-around space and ten loading points. At the same time, it integrates electromechanical and data acquisition equipment. This set of unique test equipment in the world can reduce the test cost by more than 50% and improve the efficiency by more than 4 times.

 

Professor Luo Yaozhi's team has long been committed to the research of spatial structure systems, developed new forms of rigid, flexible, and rigid-flexible spatial structures, established the analysis theory of tension structure, grid structure, and deployable structure, developed advanced test equipment, manufacturing technology, and construction methods, and achieved systematic and leading results, which are widely used in airports, high-speed railways, exhibitions Energy and other fields and national science and engineering.
