摘要
介绍了20世纪80年代早期设计和施工的一幢高层建筑的续建工程的设计思路和设计流程。针对这 类由于新旧规范的更替而导致抗震设防标准提高的续建工程,从总体概念设计的角度提出了对原设计进行优 化的思想,而对现有建筑的抗震鉴定及加固既遵循规范,又结合续建工程的特点适当提高抗震鉴定水平以满 足续建部分的结构安全度。并对关键部位———基础和转换大梁进行了较为详细的方案对比和计算分析,认为 工程基础满足续建要求,无须加固;采用在转换梁上部增设两层剪力墙来共同承担上部荷载的加固方案。
The design method and process of a tall-building's reconstruction that was designed and constructed in the early 1980's are introduced.The idea that optimizes the original design with the whole concept design is brought forward.The key parts of structure—pile-foundation and transform beam are analyzed.The results show that the bearing capacity of foundation is larger than the reconstructed building's weight, and the upper load can be beared by the combination of transform beam and two floors of shear wall upon it.
