Study on the judgment of damage level in initial inspection after earthquake for Steel bridge pier with concrete for corrosion protection in the base
Get PDFSteel bridge piers are used for the expressway or railroad viaducts in the city area. After huge earthquake these expressways will be expected to the emergency transportation road. It is important to investigate the safety of bridges and categorize the damage level to decide repair method，especially correspond to the aftershocks and linked earthquakes. However，until now，the bridge design code have no guideline adopted to judgment of damage level and repair. In this study，incremental cyclic loading experiments have been performed to obtain the load-displacement relationship and damage shape. And static FEM analysis for steel bridge pier with concrete for corrosion protection on the base have also been performed. From these results，the initial inspection method will be proposed，which will be able to judge the damage level of bridges in after earthquake
