大空间“马鞍形”薄壳结构的整体式覆土屋盖体系研究
发布时间：2018-08-03 09:36
【摘要】：随着城市建筑的密集化发展，体育场馆、影剧院、音乐厅等大空间建筑是当今市民公共文化生活的重要组成部分。作为一个占据着城市的重要区位与开阔场地的建筑设施，如何体现节能设计的系统性与示范性作用显得尤为重要。 大空间建筑是一个空间尺度大、结构复杂、人员使用密集的建筑类型，屋盖体系是其围护结构的关键组成部分。屋盖覆土绿化作为一个近年来逐渐被国内所公知与实践的节能设计手法，对于降低城市热岛效应、保持冬暖夏凉的空间环境都具有重要的意义。通过调研与资料收集发现，国内大空间建筑的覆土绿化应用局限于附属功能的空间覆盖，未能有效地覆盖大空间屋盖，从整体上降低室内的能耗；而整体式覆土屋盖体系就是一个针对了部分大空间建筑屋盖结构刚度的整体性特征，试图从根本上去改善大空间节能效果的构想。如何对大空间建筑屋盖结构与构造的覆土适应性做出合理的评价，构建一个可以付诸实践与推广的大空间整体式覆土屋盖体系，是本文研究的核心。 本人立足于亚热带地区气候特征，选取了结构条件较为优越的“马鞍形”混凝土薄壳结构作为研究对象，通过资料归纳、文献研究、模拟计算分析等方法，为亚热带地区的大空间建筑设计提供了结构荷载力、构造节能设计参数等的研究方法与模拟参考数据，并为研究构建一个适用于大空间“马鞍形”薄壳结构的整体式覆土屋盖结构与构造体系打下基础。 文章一共分为以下五个章节：第一章节：绪论。阐述了本课题的研究背景，结合国内外的研究现状阐述本课题的研究意义，并建立了全文的研究框架。第二章节：结构的适应性研究。运用sap2000软件模拟对比不同荷载力的条件下的结构应力水平的变化，对结构在应对覆土方面的适应性进行评价。第三章节：节能的适应性研究。运用EnergyplusDesign Builder软件模拟对比覆土绿化屋顶与裸露屋顶之间的能耗差异，定性与定量同步分析对体系的节能适应性进行评价。第四章节：构造的适应性研究。结合以上章节在结构与节能方面的研究，探讨最优化的构造层次材料选型。第五章节：全文总结。
[Abstract]:With the intensive development of urban architecture, large space buildings, such as sports venues, theaters, and music hall, are an important part of the public cultural life of the citizens today. As an important location and open site of the city, it is particularly important to reflect the system and demonstration of energy saving design.
The large space building is a large space scale, complex structure and intensive building type. The roof system is the key part of its enclosure structure. The roof overburden greening is an energy-saving design technique which has been gradually known and practice in China in recent years. It is a space environment for reducing urban heat island effect and keeping cool in winter and cool in summer. It is of great significance. Through investigation and data collection, it is found that the application of the overburden afforestation in large space buildings in China is limited to the space coverage of the subsidiary functions. It can not effectively cover the large space roof and reduce the energy consumption in the room as a whole. The idea of improving the efficiency of large space energy saving is tried to improve the energy saving effect of large space. How to make reasonable evaluation on the adaptability of the roof structure and the structure of the large space building is made, and the core of this study is to build a large space overlying roof system which can be put into practice and popularization.
Based on the climate characteristics of subtropical region, I selected the "saddle shaped" concrete shell structure with better structural conditions as the research object. Through the data induction, literature research, simulation calculation and analysis methods, it provides the structural load, the energy saving design parameters and so on for the large space building design in the subtropical region. The method and the simulated reference data are used to lay the foundation for the construction of a holistic soil covered roof structure and structure system for the large space "saddle shaped" thin shell structure.
The article is divided into the following five chapters: the first chapter: introduction. It expounds the research background of this subject, expounds the research significance of this subject in combination with the present situation at home and abroad, and sets up the research framework of the full text. The second chapter: structural adaptability research. Using SAP2000 software to simulate and compare the structure under the conditions of different loads. The adaptability of the structure in response to soil covering is evaluated. The third chapter: the adaptability of energy saving. Using EnergyplusDesign Builder software to simulate and compare the energy consumption difference between the green roof and the bare roof, the qualitative and quantitative analysis of the energy saving adaptability of the system is evaluated. Fourth chapters The study of structural adaptability. Combined with the research on the structure and energy saving of the above chapters, the optimization of structural hierarchy material selection is discussed. The fifth chapter: the full text summary.
