PROJECT DURATION: Design 2012

PEDELTA’S KEY PERSONNEL: Juan Sobrino, PhD, PEng, PE; Leonardo Rosillo, MSc; Nelson Betancour, MSc

PROJECT DESCRIPTION

Seismic design has conditioned the conceptual design of the bridge as it is located in a high seismic region. The bridge is a 377 ft (115 m) long steel arch built in 1974. The bridge is located in the road link between Tocaima and Agua de Dios, crossing the Río Bogotá river 72 mi (116 km) away from Bogotá.

Due to the increase of traffic loads and the flexibility of the light-weight steel structure, the bridge presented significant vibrations under heavy loads. Consorcio Devisab (Concesionaria del Desarrollo Vial de la Sabana), decided to retrofit the bridge to improve its behavior until it can be replaced. The bridge consists of a two parallel tied arches, with a main span of 377 ft (115 m). The platform is 38 ft (11.8 m) wide and consists of a concrete deck supported on longitudinal steel trusses 4 ft (1.50 m) in height. Vertical hangers are spaced at 24 ft (7.6 m).
