Nowadays, the improper disposal of electronic waste (E-waste) is creating environmental pollution and health problems in developing countries. Moreover, the corrosion of steel bars reduces the serviceability of reinforced concrete columns. Although many researchers studied the behavior of glass fiber reinforced polymer (GFRP) bars in concrete columns, none of the studies investigated the structural performance of structural fiber-reinforced E-waste concrete (SFEC) columns having GFRP reinforcement. The present study aims to examine the structural performance of GFRP reinforced concrete circular columns consisting of polypropylene structural fibers (GSFEC columns) under concentric and eccentric loading. Identical steel bars reinforced concrete columns (SSFEC columns) were also manufactured and tested to failure under the same loading conditions. The experimental program consisted of 18 circular columns (1200 mm × 300 mm) to measure the axial capacity (AC), axial deflections, failure modes, and cracking patterns under different eccentric loadings. The AC of SSFEC columns was larger while the ductility was lower than GSFEC columns. Both GSFEC and SSFEC columns illustrated similar damaging behavior. The eccentric loading led to similar decreases in AC for both GSFEC and SSFEC columns.

This paper presents an investigation into the flexural behaviour of reinforced concrete beam with opening reinforced with two different materials i.e., steel and Glass Fiber Reinforced Polymer (GFRP). Comparison study between the two different materials were carried out and presented in this study through non-linear Finite Element Method (FEM) using the commercial ABAQUS 6.10 software package. The performance of the opening beam reinforced with GFRP is influenced by several key parameters. Simulation analyses were carried out to determine the behavior of beam with opening subjected to monotonic loading. The main parameters considered in this study are size of opening and reinforcement diameter. The results show that GFRP give 23%-29% more ductility than steel reinforcement. The result also shows when the size of opening change from 200mm to 150mm or from 150mm to 100mm the ultimate load capacity increase by 15%. In general, good agreement between the Finite Element (FE) simulation and the available experimental result has been obtained.
