This study has been considering cable stayed bridge for structural health monitoring purpose . To monitor the bridge, 6 different locations (like 2 points from deck, 2 points from pylon, 1 points from side span and 1 points from girder) were introduce to find the satellite signal received from the GPS antenna. According to the World Geodetic System 1984(WGS-84) coordinate system, the GPS station signal was measured in the 6 observed points. After that, Statistical moment analysis is applied to assess the condition of those 6 position of this long span bridge. Finally, the Statistical moment analysis results clearly indicate the present condition of the long span bridge at 6 different locations. The time series statistical moments really able to detect the damage condition and localization of the long span bridge.

The intent of this research is to apply DOE in mix proportioning of high strength self-compacting concrete (HSSCC) and to assess the effect of different process parameters on HSSCC. The effect of water-binder ratio, cement content, fine aggregate percentage, fly ash content and superplasticizer content on compressive strength, passing ability, and manufacturing cost were studied.
