Flexural Behavior Analysis and Design Approach for R.C. Beams by Hybrid Reinforcement of Steel Rebars and HDPE Uniaxial Geogrids

Abstract The objective of this study is to investigate a hybrid reinforcement method for concrete beams, which consists steel rebars and HDPE (high-density polyethylene) uniaxial geogrids, by developing an experimental comparative investigation between utilizing different grades layers geogrids as the primary or extra rebars. experiments included 24 reinforced beams in order provide rich data flexural behavior analysis design approach. For detailed analysis, strain gauges were connected geogrids. Analysis results shows that using provided greater benefits (such energy absorption capacity, ductility index, ultimate load, steel-yield load) more effective utilization better performance, lower deformation values corresponding cost ratios) than conventional Simple equations added calculate bending necessary geogrids’ grade, number
