摘　　要：文中以某博物院增加夹层改造工程为例,研究了新增夹层采取不同连接形式对结构整体抗震性能的影响和大重量仿生机器在楼板上行走的舒适度问题,研究得出新增夹层与原结构优先采取铰接连接,可减少对原结构的加固工程量;可以通过增大钢梁刚度的方式来改善楼板舒适度。并介绍桩基补强技术和钢梁与型钢混凝土柱连接加固节点大样,可为同类型改造工程参考。Taking a renovation project of adding mezzanines to a museum as the case,we study the impact of differ⁃ent connection forms on the seismic performance of the structure and the comfort of heavy bionic machines walking on the floor.The study shows that prioritizing hinged joints between the adding mezzanine and the original structure reduce the amount of reinforcement work.The floor vibration can be improved by increasing the rigidity of the steel beams.We also introduce the pile foundation reinforcement technology and the connection between steel beams and type-steel concrete columns,for reference in similar renovation projects.
