Flow and Expansion:A Design Approach for Building Transformation Based on Structural Underpinning Technology

结构托换能够有效降低空间改造的工程量,是建筑改造工程朝向精细化、轻量化、低碳化发展的有效措施之一。结构托换技术与空间设计目标的协同需要跨专业的方法体系指导。文章从形态学视角概括了结构托换技术的类型及与其协同的空间设计策略,提出了结构与空间协同的托换空间设计方法,最后通过在南京小西湖街区部分建筑改造项目中进行实践验证,为托换技术与空间改造设计的协同运用提供了理论基础和实证参考。

Structural underpinning can effectively reduce the amount of building transformation and is one of the effective measures for refinement,lightweight and low-carbon development.The synergy between the structural underpinning technology and the spatial design objectives demands the guidance of an interdisciplinary methodology.This article summarizes the types of underpinning technology and the design strategies of underpinned space from a morphological perspective and finally validates the design methodology in some of the building transformation projects in Xiaoxihu,Nanjing,providing theoretical foundations and empirical references for synergistic application of underpinning technology and spatial transformation design.
