建筑震后安全状态与结构最大层间位移角间的经验性关系研究
Empirical Relationship Between Post-Earthquake Safety Condition and Maximum Interstory Drift Ratio of Buildings
摘要
Abstract
Although seismic monitoring technologies provide an effective mechanism for acquiring structural responses during earthquakes,utilizing monitoring data for rapid building safety evaluation still faces critical challenges,including inconsistent criteria for safety state classification,highly dispersed engineering demand pa-rameter(EDP)thresholds,and limited structural applicability.To address these issues,a unified safety state map-ping is established in this study based on a"Usable-Restricted Use-Unsafe"three-level states by analyzing the performance level classification of 21 international and domestic codes.This framework facilitates the integra-tion of diverse EDP threshold data.On this basis,empirical maximum inter-story drift ratio(θm)thresholds are extracted from 45 Chinese studies published over the past two decades,encompassing six typical structural sys-tems:RC frames,RC frame-shear walls,RC frame-core walls,steel frames,steel braced frames,and masonry structures.Through statistical analysis,empirical correlations between post-earthquake safety states and θm are es-tablished,and recommended θm thresholds corresponding to the three-level states are provided.A statistical data foundation is provided for rapid post-earthquake safety evaluation and the continuous refinement of the threshold system is facilitated.关键词
