- Abstract:
- To quantify the seismic resilience of buildings, a method for evaluating functional loss from the component level to the overall building is proposed, and the dual⁃parameter seismic resilience assessment method based on postearthquake loss and recovery time is improved. A three⁃level function tree model is established, which can consider the dynamic changes in weight coefficients of different category of components relative to their functional losses. Bayesian networks are utilized to quantify the impact of weather conditions, construction technology levels, and worker skill levels on component repair time. A method for determining the real⁃time functional recovery curve of buildings based on the component repair process is proposed. Taking a three‑story teaching building as an example, the seismic resilience indices under basic earthquakes and rare earthquakes are calculated. The results show that the seismic resilience grade of the teaching building is comprehensively judged as Grade Ⅲ, and its resilience grade is more significantly affected by postearthquake loss. The proposed method can be used to predict the seismic resilience of buildings prior to earthquakes, identify weak components within buildings, and provide guidance for taking measures to enhance the seismic resilience of buildings.
- 为量化建筑的抗震韧性，提出了一种从组件层面到整体建筑的功能损失评价方法，并对基于震后损失和恢复时间的双参数抗震韧性评价方法进行了改进. 建立了可以考虑各类组件权重系数随其功能损失动态变化的三级功能树模型. 利用贝叶斯网络，量化了天气、施工技术水平和工人技术水平对组件修复时间的影响，基于组件修复过程提出了确定建筑功能恢复时变曲线的方法. 以一栋3层教学楼为例，计算了设防地震和罕遇地震下教学楼的抗震韧性指标. 结果表明，教学楼的抗震韧性等级综合判断为三级，且其韧性等级受震后损失的影响更为显著. 所提出的方法可以用于预测震前建筑的抗震韧性，识别建筑中薄弱的组件，为采取措施提高建筑的抗震韧性提供指导.
