Suzhou Bay Cultural Centre
The arching silver ribbon enwraps the Chinese Cultural Centre created by French architect Christian de Portzamparc against the current setting of conventional skyscrapers and an urban backdrop. ARUP Architects supplied structural and façade engineering services to Portzamparc throughout the design competition. The construction houses two different edifices and is located on the shore of Lake Tai in China. The superstructure spans a plot of about 100,000m2, with the ground floor distributed area accounting for 80,000m2.
The Pritzker Prize-winning architect remembers discovering the desolate plain in 2013. “I was surprised every time I went since it had been built so quickly.” It is already buzzing like a genuine Manhattan, with buildings constructed in a grid of streets and avenues that encircle a central business district. The location chosen for the cultural center installation in the competition project was remarkable. It was near the lake’s axis’s arrival and had two structures on either side. The architecture and its feature act as a symbol of that particular region.
The bold and artistic waterfront structure is segregated into 2 iconic parts- The Suzhou Opera House and Wu Jiang Exhibition Centre. The former is a music and performing space, while the latter accommodates exhibitions and presentations. The two structures are separated into sub-buildings that serve various purposes and each has a superstructure that is around 40,000 m2. The Wu Jiang Exposition Centre has a 24,000m2 museum, an 18,000m2 exhibition Centre, and a 14,000m2 Conference Centre. The 1,600-seat Suzhou Opera House offers an international-level opera theatre, a versatile stage, a modular 600-seat hall, and an IMAX theatre. A curvy, 500-meter-long metal structure ties the wings and characterizes the structure from a distance by arching up and around them in the style of an eight. These two major blocks are united by wide, braided metallic ribbons. They act as a focal feature that uses space truss structure with rotating geometry. The spacious lobby gallery in the North wing functions as the entrance to the theater-opera house and the Chinese opera. The music conservatory and the 360° cinema are accessible via this gallery. The wing separates into two museum buildings south of the waterfront: a history museum and a municipal museum with educational locations, followed by a conference and ceremonial centre.
The conception of the building was purely based on the notion of program and site. Christian de Portzamparc concluded as he worked that these wings, connected in an eight shape by their ribbon, symbolize duality in motion in the form of alternating Ying and yang. Three main components of the environment—sky, sea, and land—are combined to create a stunning mirror of the distributed structure. The ribbons, which truly stand in for the Kunqu Opera’s silk water sleeves, are intended to celebrate Suzhou’s distinct ethnic history. The top ribbon also functions as a pedestrian bridge, offering users access to the spectacular city and lake panoramas.
Different components of structural engineering were worked on by ARUP and associates. In a seismic zone, like the one where this project is situated, long-span constructions are not recommended. ARUP and associates conducted in-depth numerical calculations to establish potential load routes to comply with safety standards, and they presented a range of innovative approaches for structures to ensure structural resiliency. Arup’s structural engineers and façade designers required competency in parametric design due to the tricky interplay of the form and surface of the knotted ribbons. This remarkable structure is composed of a top ribbon that spans 100 meters, which makes it the longest in China, and a lower ribbon that is approximately 370 meters in length. To construct this complex structure, ARUP and associates employed cutting-edge digital technologies and extensive computer calculations.
A wide range of materials was utilized to orchestrate the façade of the opera house. Hanging bamboo columns of 300mm in diameter along with an elegant curtain wall system were combined to generate an elegant visual effect. At the foot of the curtain wall keel, a significant number of “sleeved column connections” were incorporated for both aesthetic and support. This distinguished design not only fulfills the architect’s original vision but also lessens wind-induced distortion of the curtain wall system. To offer fresh experiences, three display halls interlinked by footbridge and a six-story hall that stretches the length of the entire structure were created. This formed a seamless exhibition space with daylight streaming in through skylights. The opera house’s designers optimized the volume of accessible space while still fulfilling the aesthetic, technical, and comfort criteria of the top-notch performing environment.
The Suzhou Cultural puts a strong emphasis on the principle of communal cooperation. The architect desired to create something that would act as a catalyst for community meetings. The fundamental building elements include variables like volume, space orientation, and lighting. A key element in building the structure was the engineering and construction. This Center is a tribute to the diverse ethnic cultures and traditions of China, which have had a significant impact on the country’s overall development. The Center functions as a nexus for a wide range of diverse activities where people and structures are intertwined.
