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。
Parametric design methods have been around for a long time in the building field. Thanks to parametric methods, structural engineers can not only handle complex geometric models, but also improve design quality and efficiency throughout the workflow. Parametric not only provides architects with the tools to change the appearance of the building, but also allows the structural engineer’s expertise to be advanced into the parametric process from the later analysis stage. Based on the parametric model, the optimal design of the mathematical algorithm can be used to optimize the topology, shape and size of the structure to obtain a better design solution. This integrated approach can bring structural analysis to the forefront and, with progress in mind, creates the possibility that architects and structural engineers will work together to find the best solution in many scenarios. In this paper, we put forward the framework of the design method combining with parameterization and optimization. This method integrates BIM, parametric design, optimization and analysis in the early stage of design. The structural engineer can fully play the role in the design stage to get the optimized design. This article introduces the application of this design method in related project cases, and demonstrates the application value of this method.
