关于建筑设计与结构设计的实现、融合与创新呈现，是我们长期以来一直关注的建筑学话题。不仅有每年一度的《结构成就建筑之美》学术论坛，2021年10月，《建筑技艺》杂志社与东南大学、东京工业大学、华东建筑设计研究院有限公司在线上共同举办了“2021结构建筑学研究国际学术论坛”，以“建筑与结构的融合创新”为主题，来自中国、日本、欧洲各国的学者和设计师从教学、研究、创作方面分享了他们的经验与见解。

依托这次学术论坛，我们特别组织了本期专题，希望从“对话”这一角度强调建筑与结构的关系，重新审视结构在建筑学中的地位，评估建筑对结构创新的影响。此次的“对话”体现在多重层面，欧洲学者以更广泛的可持续视角对数字等建筑设计思潮的反思，爱丁堡大学安格斯 J.麦克唐纳教授从应对当前气候问题的低碳建筑需求角度，探讨了数字化设计和建造技术在建筑设计中的应用，是否基于物理定律而获得的建筑形式直接决定了结构的类型和受力的合理性，也直接导向低能源消耗的实现与否，为当下许许多多试图超越自然而非顺应自然的设计趋势敲响了警钟。东南大学郭屹民老师与华东建筑设计研究有限公司结构总工程师周健、东京工业大学教授竹内彻共同探讨两个专业间的对话方式，一种建筑与结构在形态层面上的全新的、从实现到表现的对话可能，以此窥见中国与日本在这种对话上的不同观点和思考。

“对话”在实践层面体现出更重要的意义，金箱温春从与建筑师合作的季候泥博物馆、京都车站中庭、青森美术馆、群马虫世界、昭和纪念公园花与绿文化中心项目中，总结出三种建筑设计与结构设计的关系，即共同推进、建筑主导、结构主导。由密集排列的非常规细钢柱架空于场地之上的大天鹅科普馆，以创新的“梭形柱+柱帽”撑起七巧板的燕几之翼趣味空间，脱胎于传统螺旋藻井的阶梯梁结构如同垒筑的积木营造出抱柱楼阅览大厅顶部的无限苍穹，转译传统建筑营造为斜交网格钢结构体系的普陀山宗风博物馆屋架设计，复杂单层网壳的亚青会主场馆，都是建筑师与结构工程师就不同建筑意象的共同精益探索。

在结构建筑学背景下，我们看到建筑结构在建筑学及建筑设计领域的定位正被不断讨论，建筑师与结构工程师在更多的共识下对话，正推进着建筑与结构在多元合理性下的一体化融合。

The realization,integration and innovative presentation of architectural and structural design is a long-standing architectural topic for us.Besides the annual academic forum "Architecture and Structure:Build Beauty",we co-organized the "2021 International Academic Symposium on Archi-neering Design Research" together with Southeast University,Tokyo Institute of Technology,and East China Architectural Design and Research Institute (ECADI) in October 2021,focusing on the topic of "the Integrated Innovation of Architecture and Structure",in which scholars and designers from different countries shared their experiences and insights from teaching,research and design.

Based on the academic forum,we organize this issue to highlight the relationship between architecture and structure from the perspective of "dialogue",to re-examine the position of structure in architecture and to assess the impact of architecture on structural innovation.The "dialogue" is multi-faceted.Professor Angus J.Macdonald explores the application of digital design and fabrication technology from the aspect of low-carbon buildings,and sounds the alarm for many projects that try to surpass nature laws.The discussion between Guo Yimin,Zhou Jian and Toru Takeuchi focuses on the dialogue between architecture and structure,opening up a new possibility of dialogue between the two professions.

The "dialogue" has taken on greater significance at a practical level.Yoshiharu Kanebako summarizes the co-promotion,the architecture-led and the structure-led relationship between architectural and structural design.The Swan Science Museum built on the top of the site with a dense arrangement of unconventional thin steel columns,the Wing of Swallow supported by the innovative "shuttle column+column cap" structure,the spiral dome of Baozhu Building derived from the traditional stepped beam structure,the skew spatial grid steel structure of Zongfeng Museum translated from the traditional architecture,and the complex single-layer mesh shell of the Main Stadium of the Asian Youth Games,are all completed by the joint exploration of architects and structural engineers based on different architectural imagery.

In the context of archi-neering,the position of structure in the field of architecture and architectural design is being constantly discussed.The dialogue between architects and structural engineers in greater consensus is advancing the integration of architecture and structure in a pluralistic rationalization.
