Vibration analyses for the local and global evaluation of bridges as a tool for structural retrofit

A large infrastructure system of bridges is essential to economical development of a country. Given such importance, a detailed structural inspection and evaluation is required in order to decide whether the bridges may be reinforced or retrofitted to extend their service life or whether they should...
