超高层建筑抗震韧性国内外评价方法对比研究
A Comparative Study of Chinese and Foreign Seismic Resilience Assessment Methods Based on a Super High-Rise Building
摘要
Abstract
High-rise and super high-rise buildings can cause serious economic losses and negative social impacts after an earthquake.However,the applicability of the existing seismic resilience assessment methods for super high-rise buildings remains to be explored.A case study of a super high-rise office building was conducted in this paper by adopting the Chinese("Standard for seismic resilience assessment of buildings"GB/T 38591-2020)and the US("Seismic performance assessment of buildings"FEMA P-58)seismic resilience assessment codes.The applicability and the existing deficiencies of the two codes to assess the seismic resilience of super high-rise buildings were then discussed.Some measures to improve the usability of the codes were also proposed.The results show that there are some differences between GB/T 38591-2020 and FEMA P-58 in terms of the calculation methods of the resilience indexes.Both codes take into account the scale effect by reducing the total repair cost and repair time to some extent.Resilience indexes computed using FEMA P-58 are lower partially because the FEMA P-58 has averagely greater reduction rates.Because of the higher repair labor hours of components,especially structural components,and the lower reduction rate of the workload,total repair hours computed according to GB/T 38591-2020 are longer than that of FEMA P-58.Although the construction costs of structural components provided by FEMA P-58 are lower,differences in resilience index calculation methods make the total repair cost higher than that of GB/T 38591-2020.To get more accurate and reasonable resilience indexes when applying the Chinese code in assessing the seismic resilience of super high-rise buildings,the coefficient of floor height and the current intra-and inter-story rehabilitation strategies should be revised.A more distinct calculation method should also be proposed to determine the number of workers more precisely and to calculate the repair time closer to reality.关键词
