Osama K Adwan |  An Experimental Investigation of Carbon Fiber Plates Used for High Strength Reinforced Concrete Beams Research Article Carbon fiber plates (CFPs) have been used sufficiently to strengthen reinforced concrete structures and is becoming an increasing familiar approach amongst structural engineers. In this research investigation, four-point bending flexural tests were carried out to four full-size High Strength Reinforced Concrete (HSRC) beams without CFPs and four full-size HSRC beams strengthened with CFPs. All beams were subjected to short term static loads. The experimental test results presented herein showed that the use of CFPs had remarkable effects on the ultimate carrying capacity and the structural behaviour of all beams tested. In addition, the stiffness of RC beams strengthened with CFPs have increased significantly. Osama K Adwan article from Iris Publishers The use of Carbon Fibre Polymer (CFPs) laminates is one of repair and/or strengthening methods wi...

  Nolberto Munier |  GIS and Processing data with SIMUS Review Article This is a case with a real structure from a road project in Africa, but with data changed for confidentially reasons. The purpose of this paper is to demonstrate how a powerful tool such as the Geographic Information System (GIS), may be used jointly with a Multi Criteria Decision-Making (MCDM) method. This problem is addressed using both methodologies in two different and sequential steps, when the first precedes the second. Thus, GIS produces information regarding consideration spatial interrelations of all features considered. The MCDM uses that information aiming at the selection of the best alternative. In this case, GIS provides spatial information on a certain area combining about 15 different themes involving environment, social and natural features such as villages, rivers, forests, swamps, etc. Four potential paths where detected, subject to these mentioned features, and then, the selection of the...
