[提要]  针对某高层板柱－剪力墙办公楼结构改造加固的设计要点，比较不同版本的高层建筑设计规程和抗震规范在高宽比、剪力墙最大间距及轴压比三个方面的要求，对此类板柱－剪力墙结构的改造加固进行了总结。
[关键词]  多层建筑  板柱－剪力墙结构  改造  加固

The key points of the reconstruction and strengthening design of a tall slab-column and shear-wall office building are introduced, the demands on height-width ratio, the biggest space between shear-walls and axial compressive load ratio in three editions of Code for Design of Tall Building and Code for Seismic Design of Building published in 1979, 1991 and 2002 respectively are compared. Some methods of similar reconstruction and strengthening design of the tall slab-column and shear-wall structures are adopted broadly in this project.
Keywords:  tall slab-column and shear-wall structure; reconstruction; strengthening
