某工程拔柱加固设计

摘要

There is a six-storied podium building with 3 floors basement, and the span of the frame columns is from 8.7 to 11.Om. Because of changing the function of the building, it needs to remove a column on the 5th-floor to make that floor into 17.6 by 20.5m bigger space. After comparing the retrofitting plans, 2 braces are set up on the sixth floor and a tie rod is needed between the bottoms of the braces. Simultaneously, on the sixth floor, there is retrofitting design for the corresponding columns in order to hang up the related beams of the frame.%某工程裙房高六层,含三层地下室,柱跨为8.7～11.0 m.因该建筑使用功能改变,需要拔除第5层的一根柱,形成17.6 m×20.5 m大空间.经方案比较,需要在第6层处设置二个斜撑,斜撑底设置联系拉杆,同时加固第6层对应位置柱为拉杆,吊住第6层相应框架梁.该裙房的拔柱加固设计经验,可供类似工程参考.
