The conference was organized by Beijing University of Technology, Arcplus Group PLC, Tongji University, The spatial structure Research Center of Shanghai, and Shanghai Jianke Aluminum Research Institute. The leaders of the association presented gifts to the organizers and supporting units.
Professor Zhang Yigang, former chairman of the association, made a wonderful summary for the conference: the conference has a large number of participants, the change of the council is a complete success, the technical exchanges are full and enthusiastic, and the association team continues to grow; it is expected that the association will join hands with all member units, closely follow the major national development strategy, work around smart city and low-carbon goals, seize opportunities and be brave in innovation; adhere to the leading role of the platform, actively undertake the management responsibilities of industry organizations, and further promote the healthy development of the industry.
On the morning of the 16th, the participants visited Shanghai Stadium renovation project and the Greenhouse of Shanghai World Expo Cultural Park.
Shanghai Stadium, also known as the “80,000 Stadium”, was put into use in 1997 and is a space tube truss system, which has been used for more than 20 years. In this reconstruction, on the basis of the original 65m cantilever, the roof continued to extend forward by 16.5m, and the cantilevered span reached 81.5m after the reconstruction, which is the first project at home and abroad to use the cable bearing system to extend the existing structure in a large proportion of the cantilever structure.
The Shanghai World Expo Greenhouse project base covers an area of about 46,996.27 square meters, and the maximum span of the roof is about 50m. For the first time, the roof adopts a suspended or open-string honeycomb grid alloy structure system, realizing an indoor column-free open space. The façade adopts the integrated linkage design of the structural curtain wall, which reduces the level of components and maximizes the permeability of the building. The combination of high-strength materials is used to meet the needs of lighting, anti-corrosion and structural stress in the botanical garden. For the first time, a large section closed aluminum alloy section was adopted.
