中文摘要： 大跨度复杂形体的生成单纯地遵从数学算法而偏离结构力学逻辑，构成当前国际上建筑数字化设计规避可实现性与经济性差的难题。本研究拟从"力与形态的关系"、"力与构成的关系"的结构工程学新视角，分析如何建立算法与结构力学的协同机制的关键问题；通过确定数学模型与力学模型之间的交接参数指标，建立动态的、实时的参数调度与结构计算的综合数据平台，进而通过对计算数据的综合评估以及实体模型的力学性能测试，研究形式多样性与力学性能的对应关系，形成基于协同机制下的数字化创新设计模式，最终达到完成实现复杂形式与力学逻辑有机统一的大跨度复杂结构形态数字化设计理论核心工作的目标。本研究不仅能解决当前数字化设计中复杂形态的生成与结构力学无法动态、实时协同的难题，从而在根本上为促进数字化设计潮流"理性回归"提供重要原则与指引；而且能为数字化技术冲击下传统的大型公共建筑及结构设计理论体系的科学构建与创新提供理论依据与实证参考。

英文摘要： Large-span complicated shape being created exclusively by algorithm with deviation from the structural mechanics,becomes the difficult problem of the present international digital design of large-span building, which tends to avoid poor realizability and economy. Based on the discipline-crossing theory, the key problem of building the synergetic mechanism of algorithm and stuctural mechanics is analyzed, from new view of "relationship of force and shape" and "relationship of force and composition". By determination of the related parameter index between mathematic model and the Mechanics model，a dynamic and real-time comprehensive data platform of parameter control and structural calculation is built. And the corresponding relation between multiformity and mechanical properties is studied, by comprehensive evaluation of calculated data and mechanical test. Thus new methods of digital design of large -span building based on the synergetic mechanism of algorithm and stuctural mechanics are given out, and the goal of constucting the theoretical core of digital design of large-span building is achieved, which realizes the organic combination of complex forms and stuctural mechanics. Not only can this research solve the difficult problem that complicated shape being created exclusively by algorithm without dynamic a
