摘　　要：对某办公综合楼进行了底层结构改造前的结构可靠性检测鉴定。测量结果显示该建筑物主体结构目前无明显倾斜和不均匀沉降,表明主体结构的基础已基本稳定。对框架柱、梁的混凝土强度,采用回弹-钻芯综合法进行了检测,检测结果显示,主要结构(件)的混凝土强度等级可以满足设计要求。在此基础上进行了结构鉴定,结果表明:在考虑抗震设防要求下,因荷载增大,部分前厅梁柱结构承载能力不足,应采取加固措施,并依此提出了加固建议。Some office building is carried on checking and identifying before structural remodeling. The meas- urement results show that uneven settlement and tilt of the building are not obvious. Compression strength of concrete is tested by the synthesis method combining rebound method with core drilling method. The test re- suits show that compression strength of concrete of the main structure can meet the design requirements. Mo- reover, the structural identification shows that the beam structure of the lobby should be reinforced to meet the amplification effect caused by seismic loads because of inadequate carrying capacity. Finally, some sug- gestions are proposed.
