The membrane structure of the stadium integrates into the urban life with a forward-looking perspective

Not limited to the traditional closed independent venues, the design hopes to break the stereotype of relatively closed sports buildings, fully consider the multiple possibilities in the urban context, and closely integrate the sports culture complex composed of baseball fields, training centers and physical training halls with a characteristic commercial street covered by clouds, leading the public to immerse in the shared and integrated future sports community atmosphere.

The intrinsic nature of sports architecture prompts us to rethink how to organize the intrinsic relationship between sports architecture and the city. We want to build a sports community driven by the stadium, which fully considers the multiple possibilities in the urban context and integrates them into urban life with a forward-looking perspective. At the same time, the concept of sharing and opening runs through the entire life cycle of the building, making it a link between culture and life, and giving sports buildings unique public service value.

The 19th Asian Games will be held in 2023 in Hangzhou, China. Hangzhou Asian Games Baseball and Softball Sports and Culture Center, as the largest new venue of the Asian Games, is also the largest baseball and softball sports center with the highest standard and the most advanced facilities in China. It will inject new vitality into the surrounding community and make sports become the cultural background of the surrounding.

We believe that sports buildings should not only focus on the function of sports competition, but also emphasize flexible public services to adapt to the social trend of open sharing. It is an important feature of baseball and softball sports culture center different from traditional paradigm to construct sports culture complex of sports community and make it become the gravitation core of surrounding environment and region.

The project is located at the junction of Keqiao District and Jinghu New District, Shaoxing, and is an important node and supporting facility in the future baseball community planned for construction. In order to build a sports community full of vitality, the design uses multiple urban culture superposition compound functions, starting from shaping culture, scientific planning, comprehensive utilization, and giving full play to the public service nature of sports buildings in sports communities.

The total construction area of this project is about 136,000 square meters, which is divided into two plots A and E. Plot A is mainly constructed with baseball main and auxiliary fields, physical training hall and supporting hotels; Plot E is mainly for the construction of softball main and auxiliary fields. As a sports and cultural park open to the public, the site as a whole does not have walls, whether it is a sports and cultural commercial street or a second-floor platform connecting various venues, the public can enter at any time, zero distance experience.

The project comprehensively considered the feasibility of the operation and management of the two stages during and after the Asian Games, cleverly opened the public space inside the venue, organically connected with the surrounding future community, and responded to the theme spirit of the Hangzhou Asian Games of "heart-heart integration, @ future".

"Inheriting history and reflecting regional cultural characteristics" is an important response of the design to urban culture. The design draws inspiration from the artistic conception and textile culture of Shaoxing water town, showing a unique idea that fits the region.

The venues are woven together by a ribbon-like, two-story public platform and are connected to the city streets as part of the street network. The architectural facade extracts curvilinear elements from traditional cultural symbols such as silk ribbon, scroll and tile roof, and uses curved perforated aluminum sheet material to create the image of Jiangnan with continuous waves. The perforated patterns of different proportions and forms of perforated aluminum plates give the facade a unique technical rhythm, continue the poetry of traditional textile craftsmen, and evoke the memory of regional culture.

The project comprehensively considers the feasibility of operation and maintenance management during and after the Asian Games, and cleverly connects the public space inside the venue with the surrounding community organically. At the same time, the design pays attention to the integration of architecture and natural environment, the spatial function is highly variable, and the local conditions are adapted to provide convenience for the sports and cultural community.

In addition to baseball and softball fields, the Baseball and softball Sports and Culture Center is also equipped with hotels, national fitness centers and a large number of commercial service Spaces, which can meet the diversified operational needs after the Asian Games and become an important supporting service center in the future community. Take sports service as the fulcrum, drive the development of the whole area, and enhance the popularity of the community.

The huge canopy above the venue is a major difficulty in this design. We use a bidirectional truss system with a maximum suspension of 16 meters, supported by slender steel columns. The top surface is covered with PTFE film coated with titanium dioxide, with a total area of 21,000 square meters. Each unit is slightly raised in the middle, looking from a distance like the ripples created by the breeze blowing across the water, a metaphor for the regional characteristics of Shaoxing water town.

The underside of the canopy is covered with curved white perforated aluminum panels, and the sky light diffuses through the canopy to create a rich layer of light and shadow. The translucent visual effect can eliminate the sense of oppression brought by the huge volume, and the blurred boundary between the sky is more hazy and light. The slender white structural columns look like sky light through the clouds, creating a sense of lightness and breathing. At night, in the rich LED lighting, the canopy is bright and transparent, providing a unique spectator experience during the game.

The surface curvature of the canopy is calculated by the simulation of rain and sunshine, which determines the form prototype of the middle high and the circumference low, so as to achieve the best drainage and sunshade effect. The thickest of the slender steel columns is the structural column, and the rest is the drainage tube, the cable tube and the decorative column, and the different pipe diameters represent the different functions that they undertake. The space atmosphere is clean and pure, dense and harmonious, as if shuttling through the bamboo forest. Viewed from a distance, the entire canopy seems to float above the venue, and it is like a white cloud wing, shading the entire venue under it.

Whether for the athletes of the Asian Games or ordinary residents, the new sports architecture concept can be seen from the Hangzhou Asian Games Baseball and Baseball Culture Center: the complex service function, the benign circulation system with the outside city, and the spatial phenomenon.

The project will integrate it into the city from the perspective of the sports community, and will build on the warp and weft of the city, community and cultural factors. The "wings of the cloud" are resting on the water town, anchoring the natural relationship between the place and the city, eliminating the gap between the two, and thus the dynamic sports community is born.
