Comprehensive Benefits And Typical Case Studies Of High-rise Buildings With Assembled Shear Wall System

.Assembled building is an effective way to realize the industrialization of housing and industrialization of building.The standard and technical level of traditional assembly building can no longer meet the requirements of the rapid development of the industrialization of the building.However,the cost of fabricated buildings is obviously higher than that of cast-in-place structures.For this purpose,the Metro Huisheng New Town(Public rental housing)project is selected as a typical assembly type shear wall high-rise residential building case.Through the whole process of case construction process.Comprehensive benefit evaluation analysis of economic benefits,environmental benefits,social benefits and comprehensive benefits.To propose a scientific basis for the steady development of fabricated buildings.The main results are as follows:(1)This article analyzes the economic benefits,social benefits and environmental benefits of assembly building.Determine the calculation method of economic benefits,social benefits and en-vironmental benefits.Using analytic hierarchy process and weighting method to determine the quantitative comprehensive benefit index.According to the comprehensive benefit index.Suspended construction can be built,developed steadily and vigorously developed four levels,The corresponding scores were less than 60 points,61 minutes to 75 minutes,76 minutes to 85 minutes,and more than 85 points.(2)Take the example of the assembly type integral shear wall structure of the subway Huisheng project.And through field research.Split design technology for prefabricated components,mode of tender adoption.The construction process of the high-rise residential main structure of prefabricated shear wall system is discussed in detail and studied.Definite the construction process and construction method of an assembled monolithic shear wall structure.Lay the foundation for comprehensive benefit analysis.(3)Calculate resource energy consumption and pollutant emission through typical cases and comparison projects.Obtained the environmental benefits of a high-rise residential building shear wall system.From two aspects of social compatibility and social risks.Inviting all relevant groups to score indicators.AHP is used for calculation.Quantify the social benefits of a high-rise residential building shear wall system.The statistical analysis of economic benefits,environmental benefits and social benefits by weighted scoring.Obtained the comprehensive benefits of high-rise housing and case projects for fabricated shear wall systems.Comprehensive efficiency index 81.45 points.Description assembled integral shear wall structure high-rise residential buildings are in a steady state of development.Assembled shear wall system high-rise residential buildings.Although the typical case construction costs are at a high level.In the market economy environment.In a certain degree,it affects the development of fabricated buildings.We must face up to the objective problem.However,high-rise residential buildings with shear wall system have good comprehensive benefits.In line with the guidelines and policies formulated by the country.It is necessary to steadily develop the structural system of high-rise residential building with integral shear wall.
