CARRILLO, Julián; ARCINIEGAS LONDONO, Laura  and  MOLINA FIGUEROA, Jesika Alejandra. STATISTICAL ASSESSMENT OF BRIDGE COLLAPSE IN COLOMBIA BY BLAST LOADING. Cienc. Ing. Neogranad. [online]. 2014, vol.24, n.2, pp.157-175. ISSN 0124-8170.

The recorded data of bridge collapse in Colombia by blast loading caused by terrorist attacks, from 1994 to 2014 is presented and discussed in this paper. The study includes a statistical analysis of the location, characteristics, type, and construction materials of the bridges. This analysis demonstrates that most of the collapsed bridges were located at places that are currently classified as "red zones" in the country. The study also includes the analysis of the economic, social and political impact triggered by the collapse of the bridge located on the Riecito River in Caquetá. This bridge was rehabilitated using Acrow-type bridges that are employed by the National Army of Colombia and are installed and supervised by the National Institute of Roads, INVIAS.

Keywords : bridges; collapse; blast loading; economy.
