Design of bridges for Athens - Lamia highway

PROJECT: Design of bridges for the new highway Athens - Lamia

CLIENT: Public administration (EYDE - PATHE) / ATHINA S.A.
ASSOCIATED OFFICES: A Preza - S. Pilitsis - D. Tolis and colleagues.

BRIEF DESCRIPTION:

Designs of bridges for the new highway, section Skarfia - Lamia as follows:

Final design of bridge for Brallos Intersection Ch 19+281. Simple supported voided slab, structural height 1.00m, on piles with clear opening 21.5m and a total width 34.90m. Prestressed concrete, bored piles D100 in 2 rows per abutment.
Final design of bridge for Anthili Intersection Ch 26+228. Prestressed concrete portal frame with continuous 9 openings and box type abutments with access span. The lengths of the abutments with the access spans is 20.00m on each end, made of reinforced and prestressed concrete. The entire project is analyzed as follows (with the abutments) L = 20.0 +4.0 +18.0 +20.0 +22.0 +27.0 +2 x34.0 +27.0 +5.0 +20.0 = 20.0 +191.0 +20.0 = 231.0m. The width of the deck is 13.5m and consists of 2 girders with structural height 1.40m. The two-column piers have circular cross section. The foundation is on bored piles D120 in a very difficult terrain.
Participation in the detailed design of the highway bridge of the river Sperhios Ch 21+482. This participation concerns the structural design of bridge superstructure. The bridge has 3 openings with lengths 29.3 +30.6 +29.3 = 89.2m, width 2x 17.71m, skew angle 75⁰ and total structural height 1.60m. It consists of precast prestressed beams with continuous in situ deck slab.

The project has been completed and in operation, except for the bridge of Anthili intersection.
