【摘要】 近年来国内外非线性建筑的设计和建造呈现出增长迅速、影响力大的特点,然而这类建筑的诸多性能还有待研究,屋面的集流性能即是其中之一。研究以非线性建筑屋面的雨水集流模拟为切入点,探索了如何在设计初期应用雨水集流模拟结果对非线性建筑的集流性能进行评估和优化。阐述了影响建筑集流的主要因素,分析了建筑雨水设计的关键性环节,进而对非线性建筑产生集流问题的原因进行分析。并将研究定位为降雨影响下的性能驱动优化设计,提出了在设计初期实现雨水集流模拟的必要性。对于如何实现非线性建筑的集流模拟,研究选取在参数化设计平台下对模拟程序的再开发。通过对雨水运动规律的基本原理与计算方法的研究,最终应用粒子系统原理实现了建筑屋面雨水集流路径模拟,应用DEMON算法实现了流量分配模拟。模拟结果证明该程序较精确的实现了非线性建筑的集流模拟,可为后期的集流性能评价提供技术支持。对于非线性建筑的集流性能评价方法,研究通过对已有研究的归纳总结,得出了与建筑集流性能相关的集流性能评价类型。根据影响各评价类型的主要因素,研究得出了集流性能的影响因子及其评价方法。应用集流模拟工具与评价方法,研究进一步探讨了基于集流性能评估的非线性建筑优化设计策略,系统的论述了集流性能评价因子和设计参数之间的影响关系,得出了基于集流性能的非线性建筑的优化设计策略。研究从建筑的集流性能出发,创新性的提出了基于雨水集流模拟的非线性建筑设计评价与优化策略。该研究可为非线性建筑的屋面、结构和集流设施的优化设计提供设计指导和技术支持。从集流性能角度实现了建筑设计和建筑技术的紧密结合。更多还原

【Abstract】 In recent years the design and construction of non-linear architecture shows characteristic of rapid growth and powerful influence at home and abroad. However, many properties of this kind of architecture remain to be studied, the rainwater harvesting performance is one of them. Research takes nonlinear building roof rainwater harvesting simulation as the breakthrough point and explores how to complete harvesting performance evaluation based on simulation results, so as to realize the nonlinear architectural design optimization in the initial design period. Research expounds the main factors influencing the harvesting performance of architecture, analyses the key factor of rainwater design, through which it gets the reasons of the non-linear architecture harvesting problems. It takes study as performance drive optimization design and put forward the necessity of the rainwater harvesting simulation at the beginning of design.In order to realize the harvesting performance simulation of non-linear architecture, the study selects the parametric design platform to redevelop simulation program. The research applies the principle of particle system to realize the construction of roof rainwater harvesting path simulation, and applies DEMON algorithm to realize flow distribution simulation, through the study of basic principle and method to calculate the motion regularity of rainwater. Simulation results show that the program can achieve harvesting performance simulation of the nonlinear building accurately. The program can provide technical support for the later harvesting performance evaluation. As to the evaluation method for harvesting performance of non-linear architecture,the study summarys the existing research and obtains the evaluation type related to harvesting performance. According to main parameters which influence the different evaluation types, the study obtains the influential factor and the evaluation method of harvesting performance. With the application of simulation tools and evaluation method of harvesting performance, the research discusses the optimization design method of nonlinear building and the influence between harvesting performance evaluation factors and design parameters, obtains optimal design strategy based on harvesting performance.Research innovatively proposes the simulation, evaluation and optimization strategy of the nonlinear building harvesting performance from the angle of the harvesting performance of buildings. This research can provide design guidance and technical support for the optimization design of nonlinear architectural roofing or structure and harvesting facilities. From the point of architectural harvesting performance, the reasearch would realize the close combination of architectural design and technology.更多还原
