High-Rise Residential Reinforced Concrete Building Optimisation

In the last few decades structure optimisation has become a main task in a civil engineering project. As a matter of fact, due to the complexity and particularity of every structure, the great amount of variables and design criteria to considerate and many other factors, a general optimisation’s method is not simple to formulate. As a result, this paper focuses on how to provide a successful optimisation method for a particular building type, high-rise reinforced concrete buildings. The optimization method is based on decomposition of the main structure into substructures: floor system, vertical load resisting system, lateral load resisting system and foundation system;then each of the subsystems using the design criteria established at the building codes is improved. Due to the effect of the superstructure optimisation on the foundation system, vertical and lateral load resisting system is the last to be considered after the improvement of floor. Finally, as a case example, using the method explained in the paper, a 30-story-high high-rise residential building complex is analysed and optimised, achieving good results in terms of structural behaviour and diminishing the overall cost of the structure.

传统民居绿色营造经验的提炼识别与转译方法研究

传统民居建筑中葆有大量契合现代绿色建筑设计需求的营造技艺.但随着城镇化进程的快速推进,传统技艺与匠人传承体系逐步衰落甚至消失,营造智慧濒临失传.同时,由于传统民居并非是基于“绿色”前提来进行营造的,其建筑单体本身是非预设绿色标准的,因此隐藏在传统民居建筑中的绿色营造技艺具有散点、碎片式的分布特征,具有难发现、难梳理、难转译、难应用的特点.为解决此问题,课题提出一种“基于非预设标准单体的微技术集群”研究方法,整合分析多源信息,挖掘提炼数百项地域特色民居绿色营造经验并进行科学化转译,基于健康舒适、安全耐久、资源节约等绿色性能视角,从多点聚合到集群分类,基于不同的技术层次与技术环节,形成相应的“微技术链群”,实现传统民居绿色营建智慧的创造性转化与创新性发展.
