摘　　要：根据现场检测的数据、委托方提供的房屋使用方案,对房屋加1层钢结构后进行结构安全性验算和抗震能力分析评估。鉴定结果表明,该建筑未按特殊设防类设防,局部层间位移角偏大、梁柱超筋,进而提出局部柱间增设斜撑、1层局部柱扩大截面的加固处理建议,使之满足现行抗震及相关规范要求。探讨了作为生命线工程的该类建筑,在钢结构加层后抗震鉴定评估及加固设计过程中应注意的相关问题。According to the on-site inspection data and the operational version provided by the principal,the structural security and the anti-seismic appraisal of the building with adding 1 steel structure extra-floor were done,identification results showed that the building had not special fortification,local inter-story displacement angle exceeded the limited value and beam-column overreinforced,it was proposed that riders should be added between local columns,expanding section of partial columns of the first layer,so as to meet the requirements of the current seismic and relevant specifications.As a lifeline project of this sort of building with adding steel structure extra-floors,it was also discussed the related issues in process of the aseismic appraisal and reinforcement design,which provided references for similar projects or further discussion.
