| 英文摘要 | In light of growing environmental concerns, the reduction of CO 2 emissions is increasingly vital. Particularly in the construction industry, a major contributor to global carbon emissions, addressing this issue is critical for environmental sustainability and mitigating the accelerating impacts of climate change. This study proposes the Optimal Green Design Model for Mega Structures (OGDMM) to optimise CO 2 emissions, cost-effectiveness, and serviceability in highrise buildings with mega structures. The OGDMM examines the impact of each material and structural design of main members on these three critical aspects. Analytical results for high-rise buildings (120-200 m, slenderness ratio: 2.0-8.0) demonstrate that OGDMM can reduce CO 2 emissions and costs by an average of 4.67% and 3.97%, respectively, without compromising serviceability. To ensure comprehensive evaluation, this study introduces five new evaluation indicators encompassing environmental, economic, and serviceability performances of high-rise buildings. Based on these criteria, optimised structural designs for high-rise buildings are classified into four categories according to slenderness ratio, leading to the formulation of corresponding design guidelines. The model's applicability is further validated through its application to a 270-m-tall high-rise building in Korea, showing reductions in CO 2 emissions and costs by 8.99% and 18.50%, respectively, while maintaining structural serviceability. |
