Yichang Grand Theater 宜昌大剧院
The Grand Theater is located at the head of Pinghu Peninsula, where the Yangtze River and its tributary, Huangbai River, converge within the jurisdiction of Yichang City, Hubei Province, China. It faces the Three Gorges Cruise Terminal across the river and spans a total floor area of approximately 70,000 square meters.
This is an architecture deeply connected to water, an architecture that breathes, an edifice that preserves the site's natural landscape through its construction,a theater designed for everyone.
大剧院位于中国湖北省宜昌市境内的平湖半岛之头，长江与其支流黄柏河交汇处。剧院对岸是三峡游轮码头，总建筑面积约为70,000平方米。
这是一座与水息息相关的建筑， 一座呼吸的建筑， 一座通过建筑形式保存自然景观的建筑， 一座为所有人设计的剧院。
A Fluidly Changing Theater 如水般的剧院
The design inspiration for the Grand Theater draws from the rivers of Yichang. Though appearing gentle, water harbors boundless power. Water is the soul of Yichang, a unique city nestled amid mountains and rivers. The theater, like dynamic water, reveals different shapes from various perspectives, offering a diverse canvas for interpretation. 大剧院的设计灵感来源于宜昌的河流。水看似温柔，然而却蕴藏着无穷的力量。水是宜昌的灵魂，这座独特的城市依山傍水。剧院如同流动的水，从不同的视角展现出多变的形态，提供了丰富的诠释空间。
Public Theater for Everyone 为公众开放的剧院
The building serves multiple functions, including a 1600-seat grand theater, a 1200-seat music hall, a 400-seat black box theater, along with two outdoor theaters, a rooftop theater, and a waterside theater. In addition to performance spaces, the architecture accommodates diverse functions such as education, events, rehearsals, exhibitions, cafes, restaurants, and scenic viewpoints. This versatility allows the Grand Theater to function as an all-weather, vibrant public cultural venue. 建筑，包括一个1600座的大剧场、一个1200座的音乐厅、一个400座的黑匣子剧场，以及两个户外剧场、一个屋顶剧场和一个水畔剧场。除了表演空间外，建筑还兼具教育、活动、排练、展览、咖啡馆、餐厅和观景平台等多种功能。这种多样性使得大剧院成为一个全天候、充满活力的公共文化场所。

Interaction of Various Energies 功能的交互
While perceiving and capturing the ambiance of the site, the generation of the fluid architectural form also arises from the interaction of various energies, including internal functional organization, external environmental conditions, and the civic activity spaces that permeate inside and outside, top to bottom, resulting in a balanced and inclusive state. The front-of-house public spaces take on a free and open form, offering citizens a diverse and flexible public space. The backstage is designed in an orthogonal grid format, creating semi-outdoor service spaces with a sense of retreat. 在感知和捕捉场地氛围的同时，流动的建筑形态的生成也源于多种能量的交互，包括内部功能组织、外部环境条件以及贯穿内外、上下的公共活动空间，从而形成一种平衡而包容的状态。前厅的公共空间呈现出自由开放的形式，为市民提供了多样化、灵活的公共空间。而后台则采用正交网格设计，打造了带有退隐感的半户外服务空间。

Gridshell 结构设计
The structural prototype is derived from the Gridshell envisioned by Vladimir Shukhov in the 1890s. Essentially, it is a quadrilateral mesh that can adapt to various forms. One of its significant advantages is that all members within the quadrilateral mesh or grid have equal lengths. The grid angles can vary to accommodate different shapes. Ideally, the Gridshell transforms a pure tensile net into a pure compression shell. 结构原型来源于弗拉基米尔·舒霍夫（Vladimir Shukhov）在1890年代构思的格网壳（Gridshell）。本质上，它是一种可以适应多种形态的四边形网格结构。其一个显著的优势是，四边形网格或格网中的所有构件长度相等。网格角度可以变化，以适应不同的形状。理想情况下，格网壳将一个纯粹的拉伸网格转化为一个纯粹的压缩壳体。 The primary support structure on the west side of the platform consists of six cast-in-place concrete columns. Among these, three columns incorporate vertical circulation elements such as stairs and elevators, while the remaining three columns are of a hollow square cross-section and are solely used for structural support.The stitched Gridshell seamlessly integrates structural visibility by connecting the visible 3-meter zone with the concealed 6-meter area. 平台西侧的主要支撑结构由六根现浇混凝土柱组成。其中，三根柱子结合了垂直交通元素，如楼梯和电梯，其余三根柱子为空心方形截面，仅用于结构支撑。缝合格网壳通过将可见的3米区域与隐蔽的6米区域连接起来，完美地融合了结构的可视性。
Pipe Skin 管状表皮
The portion of the building facing the peninsula features a double-layered skin. The inner layer exhibits simple yet intricate geometric forms to accommodate the complex functional requirements. The outer layer consists of continuous aluminum tube cladding that integrates with the overall structure. The distance between these two layers varies according to interior needs, creating diverse interstitial spaces for regulating the building's microclimate. The aluminum tube cladding forms a textured pattern reminiscent of water ripples, transforming the solid surface into graceful lines. Additionally, the on-site cold bending process helps reduce construction costs. 建筑面向半岛的一侧采用双层外立面设计。内层展现简洁而精致的几何形态，以适应复杂的功能需求。外层则由连续的铝管包层构成，与整体结构相融合。两层之间的间距根据内部需求变化，形成多样的夹层空间，有助于调节建筑的微气候。铝管包层形成了类似水波纹的纹理图案，将固体表面转化为优雅的线条。此外，现场冷弯工艺的应用也有效降低了施工成本。
Breathing Green Architecture 可呼吸的绿色建筑
By combining various passive and active strategies, the building becomes an active participant in the sustainable development of the peninsula's ecological environment. The floating theater also provides artists and production staff with naturally ventilated and well-lit spaces, significantly improving their working conditions and fostering opportunities for interaction between performers and the public. Extensive semi-outdoor gardens and numerous terraced gardens offer comfortable green spaces for relaxation and scenic views. 通过结合多种被动和主动策略，建筑成为半岛生态环境可持续发展的积极参与者。漂浮剧院为艺术家和制作团队提供了自然通风、光线充足的工作空间，显著改善了工作条件，并促进了表演者与观众之间的互动机会。广阔的半户外花园和众多梯田式花园为人们提供了舒适的绿化空间，供人休憩并欣赏美丽的景致。
