摘要:

为评估不同需求下城市建筑群抗震韧性,探索城市建筑群抗震韧性集成评估方法,利用树增强朴素贝叶斯网络(BN)方法构建BN模型,通过整合建筑类型、建造年代、结构类型等关键指标,快速预测不同目标地震下的建筑震害损伤状态;采用韧性指数法、韧性要素等级法、风险韧性分析法和建筑群落韧性指标评价法4种韧性评估方法,集成评价北京市丰台区某街道群体建筑的抗震韧性,并对比分析各方法的优缺点及适用性。结果表明:韧性指数法适用于快速评估建筑恢复能力;韧性要素等级法便于直观显示建筑韧性等级;风险韧性分析法对灾害不确定性和随机性有较好处理能力;建筑群落韧性指标评价法则强调功能需求对综合评估的影响。

Abstract:

To evaluate the seismic resilience of urban group buildings under different demands, an integrated assessment methodology was developed for urban building clusters' earthquake resistance. A tree-augmented naive Bayesian method was employed to construct a BN model that rapidly predicted structural damage states under various target earthquakes through multi-parameter analysis including building types, construction eras, and structural configurations. Multiple resilience evaluation theories and methods-comprising the resilience index method, resilience element rating method, risk-resilience analysis method, and group buildings resilience indicator evaluation method-were integrated to comprehensively assess the seismic resilience of group buildings in a specific street of Fengtai District, Beijing. Comparative analyses were conducted to examine the advantages, limitations, and applicability of these approaches. The results indicate that the resilience index method proves suitable for rapid assessment of building recovery capacity, while the resilience element rating method facilitates intuitive visualization of structural resilience levels. The risk-resilience analysis method demonstrates superior capability in handling disaster uncertainties and stochastic characteristics, whereas the group buildings resilience indicator evaluation method emphasizes the critical influence of functional requirements on comprehensive assessments.

Key words: urban group buildings, seismic resilience, integrated evaluation, damage states, Bayesian network (BN)
