【摘要】：隨著城市建筑的密集化發(fā)展，體育場館、影劇院、音樂廳等大空間建筑是當(dāng)今市民公共文化生活的重要組成部分。作為一個占據(jù)著城市的重要區(qū)位與開闊場地的建筑設(shè)施，如何體現(xiàn)節(jié)能設(shè)計的系統(tǒng)性與示范性作用顯得尤為重要。 大空間建筑是一個空間尺度大、結(jié)構(gòu)復(fù)雜、人員使用密集的建筑類型，屋蓋體系是其圍護結(jié)構(gòu)的關(guān)鍵組成部分。屋蓋覆土綠化作為一個近年來逐漸被國內(nèi)所公知與實踐的節(jié)能設(shè)計手法，對于降低城市熱島效應(yīng)、保持冬暖夏涼的空間環(huán)境都具有重要的意義。通過調(diào)研與資料收集發(fā)現(xiàn)，國內(nèi)大空間建筑的覆土綠化應(yīng)用局限于附屬功能的空間覆蓋，未能有效地覆蓋大空間屋蓋，從整體上降低室內(nèi)的能耗；而整體式覆土屋蓋體系就是一個針對了部分大空間建筑屋蓋結(jié)構(gòu)剛度的整體性特征，試圖從根本上去改善大空間節(jié)能效果的構(gòu)想。如何對大空間建筑屋蓋結(jié)構(gòu)與構(gòu)造的覆土適應(yīng)性做出合理的評價，構(gòu)建一個可以付諸實踐與推廣的大空間整體式覆土屋蓋體系，是本文研究的核心。 本人立足于亞熱帶地區(qū)氣候特征，選取了結(jié)構(gòu)條件較為優(yōu)越的“馬鞍形”混凝土薄殼結(jié)構(gòu)作為研究對象，通過資料歸納、文獻(xiàn)研究、模擬計算分析等方法，為亞熱帶地區(qū)的大空間建筑設(shè)計提供了結(jié)構(gòu)荷載力、構(gòu)造節(jié)能設(shè)計參數(shù)等的研究方法與模擬參考數(shù)據(jù)，并為研究構(gòu)建一個適用于大空間“馬鞍形”薄殼結(jié)構(gòu)的整體式覆土屋蓋結(jié)構(gòu)與構(gòu)造體系打下基礎(chǔ)。 文章一共分為以下五個章節(jié)：第一章節(jié)：緒論。闡述了本課題的研究背景，結(jié)合國內(nèi)外的研究現(xiàn)狀闡述本課題的研究意義，并建立了全文的研究框架。第二章節(jié)：結(jié)構(gòu)的適應(yīng)性研究。運用sap2000軟件模擬對比不同荷載力的條件下的結(jié)構(gòu)應(yīng)力水平的變化，對結(jié)構(gòu)在應(yīng)對覆土方面的適應(yīng)性進(jìn)行評價。第三章節(jié)：節(jié)能的適應(yīng)性研究。運用EnergyplusDesign Builder軟件模擬對比覆土綠化屋頂與裸露屋頂之間的能耗差異，定性與定量同步分析對體系的節(jié)能適應(yīng)性進(jìn)行評價。第四章節(jié)：構(gòu)造的適應(yīng)性研究。結(jié)合以上章節(jié)在結(jié)構(gòu)與節(jié)能方面的研究，探討最優(yōu)化的構(gòu)造層次材料選型。第五章節(jié)：全文總結(jié)。
[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.
