青岛加洲国际客运中心项目为A级高度大底盘双塔楼框架-核心筒结构,主体完工后成为烂尾楼。现由于建筑功能改变及立面调整,对其进行了外扩、增层、拔柱、开洞、补洞等一系列改动。由于原设计整体计算参数有一定富余,故后续设计使用年限取50年,按现行规范进行加固改造设计。设计中充分发掘已有结构潜力,尽量避免梁板加固;采用钢箍板加固底部暗柱以保证加固后的底部加强区满足现行规范要求;通过增设钢斜撑形成平面桁架结构,从而实现1层大堂拔柱;合理设计增层生柱及新增悬挑梁,避免了过量植筋对原结构的损伤。通过采取以上措施,较好地实现了建筑功能的改变。
Qingdao California International Passenger Transport Center project for the A-level large chassis twin towers frame - core tube structure, the main body after completion of the uncompleted floor. Now due to changes in building functions and facades adjustment, carried out a series of changes such as external expansion, layering, pulling columns, holes, holes and so on. As the original design of the overall calculation parameters have some surplus, so follow-up design life of 50 years, according to the current specifications of the reinforcement design. The design fully explores the potential of the existing structure and avoids the reinforcement of the beam slab. Steel hoop reinforcement is adopted to reinforce the bottom dark column to ensure that the reinforced bottom reinforcement area meets the requirements of the current codes. The flat truss structure is formed by adding steel bracing so as to realize the first floor Pull the column in the lobby; reasonably design the additional layers of raw columns and the new cantilevered beam to avoid the damage caused by excessive planting bars on the original structure. By adopting the above measures, the function of the building is better realized.
