| Abstract: |
Chilina Bridge is a 562 long prestressed concrete viaduct with two 11.3 m wide decks in the city of Arequipa (Peru) with span scheme: 100+157+142+102+61 m. Free Cantilever Method construction is used. High seismicity in the area reaches Peak Ground Acceleration of 0.6 g and involves special analysis and detailing. The new bridge will become the largest urban bridge in Peru when completed. Construction started in March 2013 and will be finished by the end of 2014. Seismic analysis is done according to AASHTO specifications for a 1000 year return period Earthquake. Seismic displacement demands are as high as 90 cm and 45 cm in transverse and longitudinal direction. |
