［摘要］某工程原设计方案为地上三栋高层办公塔楼，地下４层，在大部分地下室已施工至±0.000后停工。新的建筑方案对地下室功能和布局进行了调整，对地上塔楼进行了修改和加层。以塔楼B为例，介绍了新的结构设计在框架柱数量、剪力墙厚度、楼面梁布置及荷载取值等方面进行的一系列优化，更好地满足了建筑设计的要求，而且结构设计更趋于合理、经济，同时在现有地下室施工情况下顺利地进行了后续施工。

Abstract:

The previous design scheme of a project included 3 high-rise office towers aboveground and 4-story basement underground. The construction was shut down when the basement construction was almost completed and the relative elevation reached ±0.000. In new architecture scheme, basement function and layouts were adjusted as well as the tower aboveground, and the tower floor numbers were added. Take tower B as example, a series of optimization items were introduced including column numbers, shear wall thickness, beam arrangement and load value assignment. The new structural design tends to be more reasonable as well as economic, and meets the architecture demand much better. The continued construction was carried out successfully under the existing basement construction conditions.

Keywords: reconstruction; frame-core wall; structural optimization design
