[Abstract]:The construction industry is one of the most energy-consuming industries in the world, and it is also an important source of greenhouse gas emissions such as carbon dioxide. Energy crisis and other global problems are increasingly prominent. It is imperative to vigorously develop green buildings to achieve sustainable development in the field of architecture. Green building is to save resources to the maximum extent in the whole life cycle of buildings. In order to protect the environment and reduce pollution, reduce carbon emissions, and harmonious with the nature of the building. This paper takes the high-rise shear wall structure as the research object. In order to reduce the carbon emission of the building structure system to make the building more green as the optimization design objective, the main research contents are as follows: 1) Analysis to evaluate the scientific nature of green building by building carbon emissions. To determine the basic data for the calculation of the carbon emissions of building based on the theory of building life cycle evaluation. The carbon emission factors of the main building materials in the concrete structure system are obtained. For the quantitative evaluation of the green degree of the structural system, the paper introduces the seismic calculation of the shear wall structure and the calculation method of the internal force and displacement. At the same time, the concept and mathematical model of optimization design of high-rise shear wall structure are introduced. On this basis, the basic idea of the optimization design of high-rise shear wall structure based on green building is determined. Taking a high-rise shear wall structure residential building in Xi'an as an example, the layout and quantity of shear wall are taken as an example. The thickness of shear wall is taken as the variable of optimization design, and the SATWE software is used to model and calculate the analysis. It is concluded that the quantity of shear wall can be reduced by optimizing the arrangement of shear wall. Reducing the thickness of the shear wall can optimize the seismic performance of the structure and reduce the carbon displacement of the structure system. Thirdly, the shear wall thickness and the material strength of the structure are taken as the optimum design variables. After optimization, the mechanical performance, seismic performance and stiffness of the structure become more reasonable. The carbon emission of the structure system is obviously reduced. The optimal design approach of high-rise shear wall structure based on green building is obtained, which provides a reference for designers to design green structure and optimize structure.
