摘要
地震对区域建筑的破坏力对震后应急决策有着重要意义。为满足地震应急管理部门及时了解地震破坏力的迫切需求,充分利用现有强震动台网的记录数据,清华大学等13家单位共同编制了T/SSC 1—2021《基于强震动记录的地震破坏力评估》标准。标准是在国内外100余次基于强震动的地震破坏力评估的成功经验上制定的。标准基于强震动记录和城市抗震弹塑性分析方法,充分利用了当地强震台网的观测数据,可以更好地考虑当地地面运动特征,能更好地反映不同结构动力学特性和地震动特性,制定了更加丰富的评估内容。同时,标准建议了评估区域的建筑属性数据确定方法,可以更好地体现本地建筑特征。本文对标准的编制背景、标准用户、标准主要内容、标准特色、典型案例进行了介绍。标准的实施将为震害评估、应急救援和地震工程科学研究提供重要参考。
The seismic destructive power to the buildings on a regional scale is of great significance for emergency decision-making after the earthquake.In order to meet the urgent need of earthquake emergency management departments to timely understand the seismic destructive power and make full use of recorded data from the strong motion network,13 institutions including Tsinghua University jointly compiled the group standard,namely T/SSC 1-2021 seismic destructive power evaluation based on strong motion records.This standard was developed based on more than 100 successful experiences of seismic destructive power evaluation using strong motions at home and abroad.Based on strong motion records and city-scale nonlinear time-history analysis method,the strong motion data of the local strong motion network can be fully utilized,and the characteristics of the ground motion and the dynamic characteristics of different structures can be better considered.In addition,this standard can provide more refined seismic damage assessment results.Meanwhile,this standard proposes a method for determining the building attribute data of the target area,through which the characteristics of local buildings can be better considered.The preparation background,users,content,features,and typical application of this standard are introduced in this work.The implementation of this standard will provide an important reference for earthquake damage assessment,emergency rescue and earthquake engineering scientific research.
