The modular elements are light weight, can be easily assembled for structural support of an overhead transmission lines. The member stresses were monitored using strain gauges during full scale testing. Mathematical model of 3-Dimensional panel were generated using standard FEM software to study the analytical correlation with the experiments. The results from this study illustrates the light weight FRP structural profiles is an alternate sections to the conventional rolled steel angle sections used in power transmission line towers.","PeriodicalId":162063,"journal":{"name":"International Journal of Civil and Structural Engineering","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126479640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wireless based sensors technology has been shown the potential to serve as low cost to substitute traditional cable based monitoring and increasing the facility of the real time bridge monitoring. How ever, bridge monitoring systems using the wireless sensor is still malfunctioning due to the lack of the proper sensor placement techniques. In addition, the improper sensor placement on the bridge girder increase the total number of sensors and the overall cost of installation and maintenance of bridge health monitoring system. In this paper, the sensor placement technique was developed based on the priority of the flexure and shear behavior of the girder; to optimize the sensor used on the girder and to minimize the overall cost of the bridge girder monitoring system. GUI system was developed using Matlab toolbox for monitoring the bridge girder continuously. GUI system would be helpful to evaluate the bridge girder condition based on the monitoring data of wireless based sensor technology.","PeriodicalId":162063,"journal":{"name":"International Journal of Civil and Structural Engineering","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133802661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A commercial finite element computer program ANSYS 12.0 has been used to perform a structural behavior of RGPC beam. Using various parameters like stress, strain and Poisson's ratio obtained from experimental results, a model has been created in ANSYS 12.0. Experimental based analysis has been widely used as a means to find out the response of individual elements of structure with reinforcement ratio of 0.87% and 1.75% for grades M20, M25, M30 and M35 with companion specimens like cylinders. The results from both ANSYS 12.0 modelling and experimental data were compared. The observation was mainly focused on RGPC beam behavior at different points of interest which were then tabulated and compared. Due to high stiffness of reactive geopolymer concrete, the actual deflections of the beams were found to be slightly low allowable values under service loads. In ANSYS 12.0 the deflection obtained was found to be low due to meshing of elements in the modeling. The comparative result gives 20% difference for experimental and ANSYS 12.0.","PeriodicalId":162063,"journal":{"name":"International Journal of Civil and Structural Engineering","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131187258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
