摘　　要：选择苏联援华时期典型历史风貌建筑进行抗震鉴定与加固。通过抗震鉴定与验算发现:从平面上看,工程各层纵横内墙交界处抗震能力最弱,两端横向外墙的抗震能力次之,工程阴角、阳角处墙体抗震性能普遍薄弱;从竖向看,工程顶层内纵墙的抗震性能最好,一二层交界处、梁上部新增内墙部位抗震能力最弱。抗震加固计算表明:仅增设圈梁、构造柱仍不能满足抗震要求,还需要对内、外墙采用钢筋网片粉刷细石混凝土面层加强措施。Seismic identification and reinforcement of earthquake resistance appraisal and reinforcement for the typical Soviet-style historical buildings during the period of close relationship between China and Soviet Union. Through the seismic evaluation and checking, it is found that from the plane, the seismic capability of the hor- izontal wall at the junction of each layer is weakest, followed by outer lateral walls at both ends, and the walls at internal corners and external corners generally have a poor seismic performance; From the vertical view, the seismic capacity of the borders between the 1 st floor and the 2nd floor and the newly added inner walls at the top of beams are the weakest, while the ance. The seismic reinforcement design inner longitudinal walls at the top floor have a best seismic perform- shows that only adding the ring beam and the structural column cannot meet the seismic requirements, but also the reinforcement measures for the internal and external walls using the steel mesh to whitewash the fine stone concrete surface.
