ABSTRACT
ABSTRACT: Everyone knows that structural monitoring system is very useful tool for the measurement of structural behavior and the evaluation of structural condition. Because most of the collapses of the infrastructures are occurred progressively, the monitoring system should catch small abnormal behavior and give warning sign to mankind before the collapse. Up to now, so many monitoring systems were developed and installed in the large infrastructures such as longspan bridges, buildings, dams, tunnels, etc. Most of those systems are very complex and expensive because many sensors and data loggers should be installed in the site and unique software should be developed to handle the data loggers. The aim of these systems is focused on the observation of various structural behaviors and on the verification of design parameters as well as on the safety warning.
