| Abstract: | The Shiyang River Bridge in Yunnan is a simply-supported reinforced concrete girder bridge with six spans and two traffic lanes.The seismic capacity of the original Bridge used to be weak in the medium and strong seismic events.At the same time the carrying capacity of the Bridge was strengthened,the overall Bridge was seismically strengthened as well.In this paper,the assessment of the seismic performance,formulation of the seismic strengthening schemes,seismic design and implementation of the strengthening of the Bridge are dealt with. |
| Keywords: | highway bridge simply-supported girder seismic assessment seismic strengthening |
