摘要：
High-rise structures account for a large proportion among the buildings in the urban areas and have the characteristics of large average material consumption and high carbon emission intensity. Therefore, the low-carbon design measures on high-rise structures were studied. An enhanced assessment method of carbon emissions for life cycle is proposed based on the material production process and practical engineering characteristics. With the enhanced assessment method and the carbon efficiency as the evaluation indicator, four low-carbon design measures for high-rise structures are proposed, including the long-life measure, the isolated and damping measure, the high-strength measure and the combined measure. Considering shear-wall residential buildings, frame-shear wall, frame-core wall, steel and braced steel office buildings with the height of 24 m to 100 m and seismic intensity of 6 degree, 7 degree(0. 10g) and 8 degree (0. 20g), low-carbon design measures are applied, and their carbon reduction efficiency are studied. The results indicate that long-life design method can reduce 35. 66% - 47. 99% of the carbon emission and is an efficient measure for the carbon reduction. The isolated measure and the damping measure can achieve about 2. 03% 、17. 12% decrease in the carbon emission with an improvement in the seismic performance. High-strength measure can reduce the carbon emission by not more than 8. 50% . Comparing to a single low carbon design measure, the combined method has the best carbon reduction performance. The carbon reduction ranges from 49. 61% to 53. 29% . © 2023 Science Press. All rights reserved.
