摘　　要：2019年乌镇互联网峰会"红亭"项目为我国少数大尺度砌体拱壳结构,其造型为不规则的自由曲面壳体,为满足空间与视觉要求,主体结构采用大跨度配筋砌体拱壳。从结构找形优化、静力分析、壳体稳定性分析、人行激振、结构抗震、建造逻辑和现场堆载试验及监测等方面,全面介绍了项目设计及实施中的关键问题。研究提出的异形空间壳体结构,特别是砌体拱壳结构的结构设计方法和结构分析方法适用于多种同类的复杂空间薄壳结构。同时,研究中的试验模拟和有限元验证也将为砌体拱壳的复杂材料行为的简化分析提供一定的借鉴。The “Red Pavilion” project of the Wuzhen Internet Summit in 2019 is one of the few large-scale masonry shell structures in China.Its shape is an irregular free-form surface shell.To meet the space and visual requirements,the main structure uses large-span reinforced masonry shell.The key issues in project design and implementation were comprehensively introduced,as well as the practice in the structural form-finding optimization,static analysis,shell stability analysis,pedestrian walking vibration,structural seismic,construction logic,and on-site stacking experiments and monitoring.The structural design method and structural analysis method of the special-shaped space shell structure,especially the masonry shell structure,proposed in this study were suitable for a variety of similar complex space thin shell structures.At the same time,the experimental simulation and finite element verification in this study will also provide a certain reference for the simplified analysis of the complex material behavior of the masonry shell.
