［摘要］2019年烏鎮(zhèn)互聯(lián)網(wǎng)峰會“紅亭”項目為我國少數(shù)大尺度砌體拱殼結(jié)構(gòu)，其造型為不規(guī)則的自由曲面殼體，為滿足空間與視覺要求，主體結(jié)構(gòu)采用大跨度配筋砌體拱殼。從結(jié)構(gòu)找形優(yōu)化、靜力分析、殼體穩(wěn)定性分析、人行激振、結(jié)構(gòu)抗震、建造邏輯和現(xiàn)場堆載試驗及監(jiān)測等方面，全面介紹了項目設(shè)計及實施中的關(guān)鍵問題。研究提出的異形空間殼體結(jié)構(gòu)，特別是砌體拱殼結(jié)構(gòu)的結(jié)構(gòu)設(shè)計方法和結(jié)構(gòu)分析方法適用于多種同類的復(fù)雜空間薄殼結(jié)構(gòu)。同時，研究中的試驗?zāi)M和有限元驗證也將為砌體拱殼的復(fù)雜材料行為的簡化分析提供一定的借鑒。

Abstract: 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.
Keywords:reinforced masonry； free-form surface shell； structural form-finding and optimization； stability analysis; pedestrian walking vibration； on-site experiment
