架构师提供的文本描述。可展开竹亭是一个基于生物的空间结构，为社会服务的商业，SESC。展馆位于巴西里约热内卢帕拉蒂市的佩雷库-阿苏河的河岸上。建在海边大西洋森林的绿色校园上，计划在没有墙壁或隔断的空地上搭建屋顶，举办文化和社会活动。该展馆旨在沉浸在帕拉蒂市的文化生活中，拥有自然美景、热带生物多样性、本土文化和殖民历史。

Text description provided by the architects. Deployable Bamboo Pavilion is a bio-based space structure built for the Social Service of Commerce SESC. The Pavilion is located on the banks of the Perequê-Açu River in the city of Paraty, Rio de Janeiro, Brazil. Erected on a green campus on the seaside Atlantic Forest and planned to roof an open space, without walls or partitions, hosting cultural and social activities. The Pavilion was designed to be immersed in the cultural life of the city of Paraty, with its natural beauties, tropical biodiversity, native culture and colonial history.

Pavilion是一种由丙烯酸膜和纺织品柔性接头自应力的移动自支撑竹结构。车顶横跨模块化结构系统中的15x23米。在聚酯电缆和生物复合材料中预制的空间框架和铰接连接件快速组装，保持竹条没有扭转应力。连接的设计允许复杂的自由形状几何形状和创造性的轻质装配过程。开发了自支撑竹结构的物理模型和计算机模型。通过数值模型、比例模型和全尺度模型在交互过程中进行了结构设计和分析。

The Pavilion is a mobile self-supporting bamboo structure self-stressed by acrylic membranes and textile flexible joints. The roof spans 15x23 meters in a modular structural system. Prefabricated space frames and articulated connections in polyester cables and biocomposites are rapidly assembled, preserving bamboo bars free of torsion stresses. The design of the connections allows complex free-form geometries and a creative lightweight assembly procedure. Physical models and computer models were developed for the form-finding of the self-supporting bamboo structure. The structural design and analysis were developed through numerical models, scale models and full-scale prototypes in interaction.

屋顶应用在装载状态下运输到安装位置并在地面上展开直到到达其最终几何形状的受电弓竹格栅。竹网格由产生活性屋顶模块的丙烯酸膜覆盖。每个网格膜模块的重量为110kgf，即1,1kgf/m2。建筑结构重2.8吨，除钢筋混凝土基础外，平方米对应8kgf，空间结构极轻。

The roof applies pantographic bamboo grids transported to the mounting site in a stowed state and deployed on the ground until reach its final geometry. The bamboo grids are covered by acrylic membranes generating form-active roofing modules. Each grid-membrane module weighs 110kgf, i.e. 1,5kgf/sqm. The built structure weighs 2.8tons, except for the reinforced concrete foundations, corresponding to 8kgf for square meter, resulting in an extremely lightweight space structure.

装配过程不需要起重机或重型设备。模块化结构是由一个使用可展开的双脚、滑轮和电缆的移动提升系统建立起来的，在地面上执行大量的装配步骤。该结构完全可逆，可在30个工作日内安装。该结构提供了一个安静和干净的使用装配现场，敏捷的执行，少产生浪费，低能耗和最小的环境影响，在其生命周期。可展开竹空间结构展馆在生产、维护和后期使用过程中提供了一个可持续的低碳生命周期。所开发的生物材料可以完全包装和运输。

The assembly procedure doesn’t need cranes or heavy equipment. The modular structure is erected by a mobile lifting system using deployable bipods, pulleys and cables, performing a large number of assembly steps on the ground. The structure is fully reversible and mountable in 30 working days. The structure presents a silent and clean use of the assembly site, an agile execution, little waste generation, low energy consumption and minimal environmental impact in its lifecycle. The Deployable Bamboo Space Structure Pavilion presents a sustainable and low-embodied carbon lifecycle in the production, maintenance and post-use processes. The developed biomaterials can be fully packed and transported.

一种新的可持续封装技术，竹竿保护材料的户外暴露，保存秆的水分，真菌和昆虫。该封装技术采用棉织物、土、聚乙烯醇胶和蓖麻油聚氨酯聚合物组成的生物复合涂层，用外生物基薄壳保护杆。封装是一种生物气候的解决方案，即使在竹竿制造后也可以干燥，这是由于空气通过压差交换的能力，也就是在材料呼吸的情况下进行的处理。它适用于竹子的建筑，因为竹秆在从森林中提取淀粉之后也会产生淀粉。竹竿以前是选择在种植园，收获和处理的烟雾渗透，不含化学防腐剂。这项研究得到了临市委-里约、UFMG和FAPERJ的支持.

A novel sustainable technique for encapsulation of bamboo poles protects material for outdoor exposure, preserving culms against moisture, fungi and insects. The encapsulation technique applies a biocomposite coat of cotton fabrics, earth, PVA glue and castor-oil polyurethane polymer, protecting poles by an external bio-based thin shell. Encapsulation is a bioclimatic solution allowing the drying of bamboo poles even after its manufacturing, due the ability of the air exchange by differential pressure, that is, a treatment where the material breathes. It is suitable for building with bamboo, since culms produce starch even after its extraction from the forest. Bamboo poles are previously selected in the plantation, harvested and treated by smoke-penetration, free of chemical preservatives. The research received support of PUC-Rio, UFMG and FAPERJ.
