摘   要 ：既有结构为规则性超限的超限高层建筑。针对超限情况 ，通过新增剪力墙将原框架结构改为了框 架剪力墙结构 、新增连廊措施后，将原结构变为了高度和规则性均不超限高层建筑。并对加固改造后的结构进行了弹性分析 、设防地震和罕遇地震下弹塑性时程分析。结果表明：原框架结构改为框架剪力墙结构后，提高 了结构抗震性能，结构抗侧刚度提高约 60% ,  承载力水平提高约 40% ,  降低框架柱受力和抗震等级，减少框架 柱加固工程量约 80% 。结构各项指标均满足规范要求，达到了“小震不坏， 中震可修，大震不倒 ” 的抗震设防 要求。工程所采的加固改造技术措施合理有效，安全可靠 ，加固改造经济成本降低，综合效益显著，可为以后 类似工程提供参考。

Abstract: Existing high-rise buildings with regular exceeding limits.In response to the situation of exceeding the limit, the original frame structure was changed to a frame shear wall structure by adding shear walls, and after adding corridor measures, the original structure was transformed into a high-rise building with height and regularity not exceeding the limit. The elastoplastic time-history analysis of the reinforced structure, fortification against earthquakes and rare earthquakes are also carried out. The results indicate that after the original frame structure was changed to a frame shear wall structure, the lateral stiffness of the structure is increased by about 60%, the bearing capacity level is increased by about 40%, the stress and seismic grade of the frame column are reduced, and the reinforcement work of the frame column is reduced by about 80%. All the indicators of the structure meet the requirements of the code, and achieve the seismic fortification requirements of "small earthquake is not bad, medium earthquake can be repaired, and large earthquake cannot be prevented". The technical measures adopted in this project are reasonable, effective, safe and reliable, the economic cost of reinforcement and transformation is reduced, and the comprehensive benefits are remarkable,it can provide reference for similar projects in the future.
