Zhengzhou City, Henan Province, China
The Architectural Design and Research Institute of HIT completes a Zhengzhou Grand Theater, a mega-structure that mimics “a boat of art sailing on the Yellow River” designed as the highest-level performing arts landmark in the Central Plain Region of China.
The new theater would accommodate a 1,687-seat theater hall, an 884-seat concert hall, a 421-seat multifunctional hall, a 461-seat opera rehearsal hall, and other ancillary spaces.
Through contemporary architectural languages, the project creates the image of a majestic “ship,” which conveys the significant culture and civilization of Central Plain.
When night falls, the bright lighting indoors penetrates the large glass curtain wall, and the “sails” transform into a giant curtain.
The audience’s activities inside are revealed obscurely, which vividly interprets the artistic character of the Grand Theater as a performing arts building.
This project is a large comprehensive performance arts building. Its high complexity is reflected in the following aspects:
The four major independent halls are integrated in this large comprehensive building, with multiple functions, large audience capacity, and complex circulations.
In light of it, the design needed to reasonably organize the layout of all functional halls and the circulations of both people and logistics.
The design had to fully respond to the different acoustic requirements of the four major halls, to ensure quality sound effects and avoid mutual acoustic interference.
The project is a long-span building, with a length of 204m.
Based on the characteristics of the architectural form, the exterior structure adopts steel trusses, and the roof is formed by grid structures, supported by three tower-like concrete bottom structures, together creating a new, distinctive mixed structural system.
Besides, the project employs a variety of transfer structures, such as a supporting column, Y-shaped column, and lapping column.
The architecture consists of four performance halls. There are special requirements for fire compartments, the width of the evacuation path, the number of emergency exits, and evacuation distance.
Specifically, as the fire compartment exceeds the conventional area limit, a performance analysis was necessary.
Simplification is at the core of the design. By combing “sails” of different curvatures with oblique textures, the facade units were optimized into irregular hyperbolic surfaces.
Modeling and parametric design were applied to make repeated comparisons of the unit division solutions.
Eventually, a 2mx3m vertical unit that can be lifted for the assembly was chosen. Those modular units create a curvy form that emulates the irregular flow of the Yellow River featuring nine major curves.
Meanwhile, those components could be manufactured in a standardized way, hence simplifying the construction process and saving costs.
The ingenious hemispherical facade with a concave, reminiscent of the shape of hemispherical nails of the traditional Chinese palace gates, creates an exterior that blends both traditional and innovative features.
The use of self-supporting U-shaped aluminum tubes and the manual wire drawing and coating techniques enable those aluminum components to break free from the keel and appear more graceful.
At the same time, the manual wire drawing process created a multi-layered bronze-tone texture.
Combined with the cultural context of the Xia and Shang dynasties, the Yellow River, and the local opera elements, it presents the building’s historical significance both visually and metaphorically.
Another creative design is reflected in the water drop-shaped skylights featuring a light-guiding internal surface, which reduces the weight, as well as construction and maintenance costs compared with traditional reflective glazing surfaces.
The roof adopts a combination of steel mesh, lightweight steel-frame composite panel, and TPO waterproofing membrane, which reduces the construction cost, improves the safety of the waterproofing system, and enhances the roof’s wind resistance as well as sound insulation performances compared with traditional standing seam steel roofing.
Zhengzhou Grand Theater has received more than 20 provincial and municipal delegations and held numerous events, including the 2021 Zhengzhou Spring Festival Gala, the opening ceremony of the Yellow River Culture Month, performances by visiting theaters of other provinces, and more.
It also provided a venue for the ceremony of the 29th Golden Rooster and Hundred Flowers Awards and various cultural performances, gaining wide recognition from society.
In the future, Zhengzhou Grand Theater will strengthen its role in invigorating the performing arts market and making cultural events more accessible to the public.
It will continue to enhance the cultural image of the city and itself as a benchmark of local cultural landmarks, so as to contribute to constructing “cultural Zhengzhou, civilized Zhengzhou.”
