Study On The Overall Green Roof System Of "Saddle-shaped" Concrete Shell Structure On Large Space Buildings

With the intensive development of urban architecture, stadiums, theaters, concert halls andother large space buildings have become an important part of today’s public and cultural life.As the construction facilities occupying the most important location and open area in the city,it’s particularly important for them to reflect the systemic and demonstration of energy-savingdesign.Large space building is a building type which has large spatial scale, complex structure andpersonnel-intensive, while the roof system is a key component of its envelope. As a wellknown domestic saving design techniques and practices in recent years, green roof hasimportant significance to reduce the urban heat island effect and to keep a cool internalenvironment in the building. Discovered form research and data collection, the application ofgreen roof on large space buildings is limited to the spatial coverage of subsidiary functionalspaces in China, which is failed to effectively cover a large roof space, reducing the energyconsumption indoors. As an idea to radically improve the energy savings of large spaces, theoverall cover soil roof system work for the integrated features of large space building roofstructure stiffness. The core of this study is to make a reasonable evaluation of the cover soiladaptability of large space building roof structure and construction, and to create an integralcover soil roof system which can be put into practice and promotion.Based on the climate characteristics of subtropical regions, we select the ‘saddle shaped’concrete shell structure as the research object which is more favorable on structural conditions.Through the inductive method, literature research, analysis, simulation, we provide powerloads, structural design parameters such as energy-saving methods and simulation referencedata for the large space building design in subtropical regions, and build a foundation forlarge space ‘saddle shaped’ integral cover soil shell roof structure and tectonic structure of thesystem.The following article is divided into five chapters altogether. Chapter one: introduction.Describes the research background, the current status and explained the significance of thisissue, and to establish a framework for the full text of the study. Chapter two: adaptability of structure. Use the sap2000software to compare the stress level changes on different loads,and make the evaluation of the structural aspects of adaptation in response to cover soil.Chapter three: adaptability of energy. Use the Energy plus&Design Builder software tocompare the consumption differences between green roofs and exposed roof, and make theevaluation of energy saving adaptability. Chapter four: adaptability of construction. Combinethe chapters above in the structure and energy efficiency research, to explore the optimummaterial selection tectonic level. Chapter five: full summary.
