Abstract:Reconstruction and strengthening design of the First Branch of Beijing People’s Procuratorate is introduced. Before design，the quality detection and identification of the old structure had been made firstly，and then  different parts of the structure were analyzed and designed according to the 1989 edition and the 2001 edition of Code for Seismic Design of Buildings respectively. The main questions resolved are as follows: the force transfer relationship between the old structure and the new one,the details of connecting new members with the old ones and the complicated connection.

Keywords:frame-shearwall； seismic； reconstruction； strengthening； steel-bonded； injection anchor； steel brackets
