Structural engineers are required to better organize the structural load-bearing and lateral force resisting components, distinguish the main components and secondary components, and make full use of the limited building space.
The project includes a cultural exchange center, a convention and exhibition center, a hotel and a full hall basement.
This interview guest Sun Xun, the chief engineer and deputy general manager of Southeast University Architectural Design and Research Institute Co., Ltd., sticks to the principle of making the best of himself Q1: What have you been busy with these years? After receiving the invitation from the magazine of Building Structure, I agreed without thinking.
The epidemic has slowed down our life and reduced our economic vitality, which has also had a great impact on our business.

I would like to bring light to you in the confusion and hesitation, and cheer for you in the process of forging ahead.
The above ground buildings are connected by air or corridors.
As a representative of excellent modern large-span theater buildings, we innovatively adopted the viscoelastic damper reinforcement technology based on deformation control to ensure minimal intervention and recovery of cultural relics; As the first modern architectural group with reinforced concrete frame in Chinese Mainland, Nanjing Heji foreign firm has also contributed wisdom to preserving its historical memory.
▲ Zidong Pavilion of the 11th Jiangsu Garden Expo in 2021 © Most of Sun Xun’s new Chinese loft style buildings have many different elevated spaces inside, with different height attached steps around them, as well as the setting of exposed and hidden layers.
We have also done these small projects with great interest, which may also be the professional fun of every architect and engineer..
The architectural design market is becoming more and more concentrated in the head, and the head enterprises are gradually sinking due to the increasingly fierce market competition, which has caused strong pressure on small and medium-sized design enterprises and localized design enterprises.
It is a happy thing to be busy these years.
It is the permanent site of the “Zhengzhou Air Silk Road International Forum”.
Basically, I can divide my working time into four parts: corporate administration, social service, professional practice, and summary learning, which just occupy a similar share.
In 2019, there was a saying: “2019 may be the worst year in the past ten years, but it will be the best year in the next ten years.” It was widely spread.
The project is located in the seismic fortification area with medium and high intensity.
Today, I think everyone will feel deeply.
If the high-rise building structure is judged strictly according to the out of limit, these new classical Chinese style buildings may be high-rise buildings with out of limit regularity.
Zhengzhou International Cultural Center is located on the north bank of Longhu Lake, Jinshui District, Zhengzhou City.
The building has a large plane scale and large span spaces are stacked inside.
▲ Rendering of Zhengzhou International Cultural Center ▲ Structural model sketch map of Zhengzhou International Cultural Center Convention Center has done some interesting projects in recent years, such as Nanchang Han Dynasty Marquis Kingdom Site Exhibition Service Center and Yichang Cuiping Mountain Tourist Service Center introduced at the Third Large Span Space Structure Conference of Architectural Structure.
Administrative work is complicated and requires experience and patience, and social service needs sincerity and enthusiasm.
To this end, the Architectural Structure magazine invited some structural experts to talk about the projects they are working on or the challenges they are facing, about the people or things they are concerned about, about their surroundings or far away, etc., and to report on what contemporary structural engineers are doing, doing, thinking and thinking.

I don’t know if it is because the epidemic has been held for too long.
Looking back on these years, it is more and more valuable to have the opportunity to participate in large and complex projects.
The exposed vertical components are also small in scale because of the architectural effect; The middle part of the attic type building is a large and transparent space, and the arrangement of the lateral force resisting components also has greater constraints.
As shown in the figure below, the Zidong Pavilion project of the 11th Jiangsu Garden Expo, which uses modern materials and technology, combined with modern technology, and uses a new method to achieve “neo classicism”, also comes from the Southeast School of Architectural History Zhu Guangya Profound accumulation and positive innovation of Professor Chen Wei’s team.
▲ Quiet campus during the epidemic in March 2020 © In the twinkling of an eye, Sun Xun’s epidemic has lasted for nearly three years, which coincided with my part-time administrative work in the company.
The current construction industry market is unpredictable, so it is better to stand on the current rather than hesitate.
These projects are not large in scale, but at the beginning of the architectural scheme design, Through the collision between architects and engineers, they have achieved and magnified the characteristics of their respective buildings in a very clever way.
Recalling the design process of the whole project, the demand for three-dimensional positive design, the organization and coordination of the upper and lower structures, how to simplify the complexity, better respond to the requirements of the building, and how to truly understand the design of steel structures, our design team has been greatly improved in many aspects.
I have never been away from the front-line design work.
When I saw some interesting and difficult projects, I couldn’t help but compare them.
In consideration of the factors such as high building height, large span building (roof) cover, large arch and inclined column with outward sloping profile, large connecting span, large overhang, etc., the project finally selects the steel frame central support structure, and achieves a good balance of safety and economy.
I sorted out the complicated space and forms in order, found suitable fulcrums in the narrow remaining space, established an appropriate structural system, and got happiness from the work.
There is no doubt that professional practice is the most relaxing and enjoyable for me.
In order to achieve a transparent effect, the main entrance forms an arch support form.
