[关键词]  高层结构 套建 复式框架-剪力墙体系 斜撑框架

The structural design methods of high-rise building enclosing a four-storied brick and concrete composite house are introduced simply. Using elevator shafts and the new built parts in the old house's two ends to increase shear walls, thus a frame-shear wall structure is formed; and frames with unbonded prestressed batter-braces are analysed inmechanics.
Keywords: enclosing another house; high-rise building; compound frame-shear wall structure; batter-braced frame; reconstruction
