There are many cases of sudden collapse of road bridges that came to an end of their service life because of the rapid degradation in the structural properties. The development of an adaptive real time control strategy based on the modified structural parameters as assessed in real time from the monitored data is having huge significance in avoiding the sudden failure of old bridge structures in service. A coupled control based on the real time monitoring of structural parameters is intended to develop in this work. At first a measured vibration output based technique to identify the modified structural parameters is implemented. Based on the structural health an adaptive controller is to be designed that enable the structure to perform satisfactorily while exposed to an uncertain excitation environment resulting from the traffic and other environmental loads.
