随着高层建筑规模的不断扩大和投资的不断增加,结构选型作为建筑结构方案设计的重要环节,对建筑功能、工程造价、社会效益等都将产生影响,正确处理高层建筑结构选型及结构优化设计问题,对高层建筑设计、施工、使用、维护等有重要意义。文章结合某工程的实例,通过分析结构选型和结构优化的重要性,解读结构选型的关键,选取适宜的结构优化方案,旨在为高层建筑提升安全降低造价提供依据。 With the continuous expansion of high-rise buildings and increasing investment, structural selection as an important part of the design of building structures will have an impact on the building functions, project costs and social benefits, and properly handle the selection and structure of high-rise building structures Optimization of design issues, high-rise building design, construction, use, maintenance, etc. of great significance. Combining with the example of a project, this article analyzes the importance of structure selection and structure optimization, interprets the key of structure selection and chooses suitable structure optimization scheme to provide the basis for high-rise building to enhance safety and reduce cost.
