（奥雅纳工程顾问深圳公司，深圳 518048）[摘要] 参数化设计方法在建筑领域的应用已有很长时间，得益于参数化方法，结构工程师不仅能够处理复杂几何模型，更在整个工作流程中提高了设计质量和效率。参数化不仅为建筑师提供了改变建筑外型的工具，同时让结构工程师的专业知识从后期分析阶段提前融入到参数化的过程中。在参数化模型的基础上，借助数学算法的优化设计能够对结构进行拓扑，形状和尺寸优化，从而得到更优的设计方案。 这种一体化方法可以把结构分析工作提到前期，在保证进度的情况下，创造了建筑师与结构工程师共同在多种方案中寻求最佳方案的可能性。本文提出了结合参数化和优化的方案阶段设计方法架构，此方法在设计前期融合了BIM， 参数化设计，优化和分析，结构工程师能在方案阶段充分发挥作用以得到优化的设计。本文通过介绍这种设计方法在相关项目案例中的应用，展示了本方法的应用价值。[关键词] 参数化;优化;方案设计中图分类号：TU201 文献标识码：A 文章编号：1002-848X(2013)S1-0815-05Integration of parametric design and optimization in preliminary designCarl You,(Ove Arup & Partners Ltd Shenzhen Branch, Shenzhen 518048,China)Abstract: Parametric design methodology has already implemented in architecture field for a long time. Nowadays engineers are benefitted through this working methodology, not only dealing with complex geometry but also incorporating whole workflow to improve performance and time saving. Parametric design is providing a media for architects to change building envelope configuration, and the whole process embeds engineer knowledge and lead them to other analysis software. Information from parametric model is inherited in optimization design then multiple algorithms are utilized, such as topological, morphological optimizations to explore design solutions as leading to a better performance design option. This overall process can shift whole structure analysis process to the preliminary design stage, so multiple design solutions can be synchronously optimized with architects and engineers together without lagging process. This paper presents a design strategy framework integrating two parts of design methodologies, parametric and optimization design. This design strategy framework incorporates BIM, parametric design, CDO and analysis process in the preliminary design the early stage design development for structure engineers to produce well-performance and optimized building structure design. Several case studies are also shown in this paper to express values for this working methodology.Keywords: parametric; optimization; schematic design作者简介：游辉陞，硕士，Email:carl.you@arup.com。
