摘要
国家能源集团主楼维修改造项目由五星级酒店建筑改造为办公建筑,改造难点主要有南侧悬挑梁板接长、斜框柱拆除、钢斜撑托柱转换、斜框柱加固改造等。介绍了本工程按后续使用年限为40年确定的抗震设计依据及地震设计参数;原结构拆除后新建结构采用钢结构方案的优势;改造后结构整体计算结果、需要加固的部位和加固措施;特殊关键节点的设计原则和设计思路,以及节点构造详图和现场实物图片。
The main building maintenance and reconstruction project of China Energy Group was to transform the five-star hotel building into the office building.Difficulties in the reconstruction mainly included the extension of cantilever beams and slabs on the south side,the removal of inclined frame column,the conversion of steel diagonal support column,and the reinforcement and reconstruction of inclined frame column.The basis and parameters of seismic design of the project based on the subsequent service life of 40 years were introduced.The advantage of adopting steel structure scheme for the new structure after the dismantling of the original structure was introduced.The overall calculation results of the reconstructed structure,the parts that need to be strengthened,and the reinforcement measures were presented.In addition,the design principles and ideas of special key joints,the detailed drawings of joint,and the physical pictures on site were introduced.
