| Abstract: |
The Bridge of Sant Julia de Loria, in Andorra, is part of the variation of the CG1 road, main entrance from Spain. SIGMA99 company is in charge of the junction engineering project and has entrusted AMATRIA with the structural design of it. The bridge is a geometrically complex structure resulting from the connection between the portals of tunnels of Tapia, currently under construction, and Grau Vell, planned for future action. The bridge also crosses the Grand Valira River and the existing CG1 road. Three slip roads connect the bridge to the road. So the bridge, or structure, has 11 spans, 7 columns and 5 abutments, with spans between 15 and 50 m. The bridge, without expansion joints except at the 5 abutments, behaves like a spatial structure where two-dimensional behaviour is significant. The deck surface is approximately 3.600m². It is developed over an area of approximately 165 m by 75 m. |
