摘　　要：目前我国在薄壳砌体结构设计方面并无相应的指导标准,薄壳砌体结构的相关案例也较少,设计时无相应参考。重庆市黄桷坪涂鸦街美术廊为一个自由曲面壳体结构,为满足视觉要求,采用砖砌拱壳结构形式,为目前国内跨度最大的自由曲面无筋砌体拱壳结构,壳体采用多孔陶土砖和高延性混凝土砌筑。采用数值分析、材料试验、足尺荷载试验的方法,从结构的形态确立、材料试验、砌筑方式、静力分析、稳定性分析和足尺荷载试验等方面,全面介绍了项目中的关键问题。结果表明,本工程采用无筋砖砌拱壳结构是可行的,为后续类似工程提供了案例参考和设计思路。At present,there is no corresponding guidance standard for the design of thin shell masonry structures in China,and there are few relevant cases of thin shell masonry structures.There is no corresponding reference for design.The Tuya Street Art Gallery in Huangjueping,Chongqing City is a free-form curved shell structure.To meet visual requirements,a brick masonry arch shell structure is adopted,which is currently the largest span free-form curved surface unreinforced masonry arch shell structure in China.The shell is made of porous clay bricks and high ductility concrete masonry.By using numerical analysis,material testing,and full-scale load testing methods,the key issues in the project were comprehensively introduced from the aspects of structural shape establishment,material testing,masonry methods,static analysis,stability analysis,and full-scale load test.The results show that the use of unreinforced brick arch shell structure in this project is feasibled,providing case references and design ideas for similar projects in the future.
