Study On The Sustainability Of Concrete Structure

With the increasingly serious problem of global resources,energy and environment,people pay more and more attention to green,low-carbon and sustainable development.As the world's most resource consuming and energy consuming industry,construction industry is the inevitable choice of building a resource-saving and environment-friendly society.As the most widely used building structure,concrete structure consumes a lot of resources and energy,and at the same time,it brings heavy burden to the natural environment.Therefore,it is urgent for structural engineers to study the sustainability of concrete structures.The purpose of this paper is dedicated to basic way to realize the sustainable summary of concrete structure technology,establish a specific,concrete structure for sustainability evaluation system is strong,simple operation.Specific contents are as follows:(1)Through reading the literature,according to the previous research results,the paper summarizes the content and connotation of the sustainable development of the building structure,and makes clear the history and current situation of the sustainable development of the concrete structure.(Chapter 1)(2)According to the concrete structure of the material,structure and structure characteristics,from the choice of concrete materials and use,layout and optimization of concrete structure component,system of concrete structure optimize the starting up the continuous technical realization way of concrete structure.(Chapter 2)(3)The sustainability of the concrete structure is the evaluation of resources and environmental impact comprehensive quantitative evaluation of the process,this paper gives the concrete construction principle of sustainability evaluation model,put forward the evaluation of concrete structure sustainability index method to quantify the ecological whole life cycle assessment method based on.(Chapter 3)(4)establish the analysis model of concrete structure lifecycle sustainability quantification,the main contents include:determining the purpose and scope of the concrete structure of life cycle assessment;on the concrete structure in the life cycle energy consumption,pollutant emissions data inventory analysis;quantitative analysis on the concrete structure of whole life cycle environmental impact analysis,including concrete structural damage to human health,ecological environment and energy resources in three aspects of sustainability.And through the standardization,standardization and weight,intuitive and easy to understand the standard ecological index.(Chapter 4)(5)In the whole life cycle of concrete structure,it has a great impact on resources and energy,which accounts for 57.1%of the total impact of the whole life cycle.In all stages of the life cycle,the raw material production stage has the greatest impact on the sustainability of the whole structure,accounting for 62.6%.Through the case structure of the main alternative structure scheme,calculation in different types of quantitative sustainable raw materials production stage,comparison of braced frame standard ecological index structure than the frame shear wall structure is reduced by 22.2%,more sustainable.To a certain extent,it provides a new idea for the optimization of concrete structure.(Chapter 5)...
