架构师提供的文本描述。竹子剧场空间结构是一个自由移动的屋顶,跨越17x12米,覆盖面积达200平方米。圆形剧场位于巴西里约热内卢天主教大学绿色校园的热带气候倾斜点上的雷纳河岸上。竹子结构是在建筑师卡洛斯·平阿里略先前设计的基础上设计的。结构设计是利用物理尺度模型和计算机模型在交互作用下,通过找形方法进行的。
Text description provided by the architects. The Bamboo Amphitheater Space Structure is a mobile free-form roof spanning 17 x 12 meters, in a total of 200m² of covered area. The Amphitheater is located on the banks of the Rainha River on an inclined site in the tropical climate, built in the green campus of the Pontifical Catholic University of Rio de Janeiro, Brazil. The bamboo structure was designed on the foundation previously designed by the architect Carlos Pingarrilho. The structural design was developed through a form-finding method, using physical scale models and computer models in interaction.

屋顶采用纺织混杂竹结构,由自应力主动弯曲梁和张拉弓格构成,产生双曲面,避免了结构构件的屈曲。自应力主动弯曲梁和弓格受外部荷载作用,其应变达到弹性极限,产生承载结构。该结构是由支撑双脚塔建立的,并呈现出自我支持的行为。6个触接式塔架和钢筋混凝土锚将结构固定在地面上,使其免受土壤水分的直接接触。
The roof applies a textile hybrid bamboo structure formed by self-stressed active bending beams and tensile pantographic grids, resulting in double curved surfaces, avoiding buckling of the structural members. Self-stressed active bending beams and pantographic grids were subjected to external loads up to an elastic limit of strain in the beams, generating a load-bearing structure. The structure was erected by supporting bipod pylons and presents a self-supporting behaviour. Six touch-down pylons and reinforced concrete anchors fix the structure on the ground, preserving it from the direct contact of the soil moisture.

网格壳模块在间隔0.5m的重叠步骤中被不连续地处理,允许空气循环和自然照明。模组空间框架采用阻力和自然声形式。凹面保持和分配声音在环境中。屋顶采用预应力丙烯酸薄膜,防止阳光和雨水。这一设计灵感来自于大自然的形式。开发了纺织柔性连接件,使其具有移动性和可部署性。可展开的结构模块表现出在脊椎动物身上的动力学特性。采用聚酯绳和生物复合材料的柔性接头设计允许结构构件中的低机械应力,不受扭转应力的影响。
Gridshell modules were disposed of discontinuously in overlapping steps 0.5m apart, allowing air circulation and natural lighting. The modular space frames apply resistant and naturally acoustic forms. Concave surfaces maintain and distribute the sound in the ambient. The roof employs pre-stressed acrylic membranes, protecting from the sun and rain. The design was inspired by the forms of nature. Textile flexible connections were developed, allowing the mobility and the deployability of the pieces. Deployable structural modules present kinetic properties as seen in the body of vertebrate animals. Flexible joints design applying polyester ropes and biocomposites allowed low mechanical stresses in the structural members, free of torsion stresses.

该结构在25个工作日内组装,采用创新技术和低环境影响的工程设计。开发了移动预制件、受电弓网格、纺织薄膜和移动式提升装置。装配过程不需要起重机和重型设备。建造的结构也是完全可逆的。该结构的适当重量为1.4吨,即7公斤/平方米,由一个以生物为基础的超轻型结构系统组成。它的轻量化和强度只能与先进聚合物的现代复合结构媲美。自2014年成立以来,竹子剧场空间结构举办了各种活动、表演和讲座。剧场是学生和大学教职员工休闲、休息和阅读的场所。该项目得到了FAPERJ里约热内卢CarlosChagas Filho de Amparo de Pesquisa do Estado do里约热内卢基金会的资助。
The structure was assembled in 25 working days, using creative techniques and an engineering design with low environmental impact. Mobile prefabricated modules, pantographic grids, textile membranes and a mobile lifting device were developed. The assembly procedure doesn’t need cranes and heavy equipment. The built structure is also fully reversible. The structure presents a proper weigh of 1.4 tons, i.e. 7 kgf/m² and consists in a bio-based ultra-lightweight structural system. Its lightness and strength are only comparable to modern composite structures of advanced polymers. Since it was inaugurated in 2014, the Bamboo Amphitheater Space Structure hosts events, shows and lectures. The Amphitheater is used by students and the university staff for leisure, rest and reading. The project received the financial support from the Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro, FAPERJ.
