哈尔滨17层住宅结构方案对比与碳排放分析

Comparison and analysis of structure design and carbon emissions of a 17-storey residential building in Harbin

为了对比配筋砌块砌体结构与钢筋混凝土剪力墙结构在碳排放量方面的优劣,对同一栋住宅建筑分别采用两种结构体系进行结构设计.通过对结构性能、工程造价的对比,以及原材料生产、运输和建筑施工过程中碳排放量的详细计算分析,结果表明,采用配筋砌块砌体结构进行中高层住宅设计,可保证与混凝土剪力墙结构相当的结构性能,同时降低工程造价10.9%,并降低碳排放量47.76 kg/m2,约合10.0%.相比于混凝土剪力墙结构,配筋砌块砌体结构建设高层住宅具有明显的低碳节能优势,是"资源节约型、环境友好型"绿色建筑结构形式.

To compare the pros and cons of reinforced concrete block masonry shear wall structure （R. M. system） with reinforced concrete short-limb shear wall structure （R. C. system ） in the area of carbon emissions, both structural systems were used for the structure design of a 17-storey residential building, and the detailed analysis of the structure performance, project cost and carbon emissions in the process of material production, transportation and construction was carried out. The results show that using the R.M. system for the construction of Multi-storey residential buildings can gain similar structure performance to the R.C. system, and at the same time reducing the project cost by 10. 9%, reducing the emissions of Carbon Dioxide by 47.76 kg/m2（ 10. 0%）. Comparing with the R.C. system, the R.M. system has the advantage of less carbon emissions and energy consumption for the construction of high-rise residential building, and it＇ s a kind of green building system with the property of ＇ resource-saving, environment-friendly＇.
