Then an example of retrofit techniques of steel truss bridge is introduced, in which the concept of damage control design is adopted introducing an girderfloor isolation system and hysteretic damper.
The structure features of bearing column girder transfer floor such as large section and complicated mechanical behaviors are introduced, which realize the transfer of structural axes.
介绍了托柱梁式转换层结构实现了上下层结构柱网改变、截面大、结构受力复杂等结构形式特点;

The results show that the failure mechanism of SRC girder transfer floor is better than that of RC girder transfer floor.
