Wheres Indonesia is a highly active tectonic zone that is prone to earthquakes. Important issue following the earthquake was retrofit structures to improvement strength and ductility structure. With the advancement of technology today has developed new innovations such as the use of material GFRP (Glass Fiber Reinforced Polymer) for external confinement structure. From the results obtained by the experimental of load capacity increased by 20% for C-2 (retrofit beam with GFRP strengthened 1 layer) compared B-1 (original beam). Retrofit beam with GFRP is added ductility as shown by the increase in displacement ductility 4% each for B-1 and B-2.

This paper presents the outcome of a study of two-span glass fiber reinforced polymer (GFRP) I-section beams susceptible to lateral-torsional buckling when subjected to gradually increasing concentrated vertical load(s) in the presence of two different types of lateral bracing schemes. It is found that loading one span results in a smaller buckling load as compared with the cases with loading in both spans regardless of the type of bracing scheme used. Also, the study shows that the addition of midspan braces for the GFRP beams results in up to 5.5 times increase in the buckling load capacity.

Abstract: Repairing the Strength and Ductility of Reinforced Concrete Column That Got Earthquake using Glass Fiber Reinforced Polymer. This study aims to identify the additional strength and ductility of reinforced concrete columns after being retro- fitted using glass fiber reinforced polymer (GFRP) and got the brunt of the earthquake. This study uses two objects tested columns, which are being tested for three times. Each column size is 350 x 350 x 1100 mm with f'c = 20.34 MPa and fy = 549.94 MPa. The testing is performed by giving a constant axial load of 748 kN and cyclic lateral load using control displacement method in order to simulate the brunt of earthquake. The results show an increase in lateral capacity of column by 43.96%. Retrofitting the column with GFRP has a ductile property, which is shown by the increase of the displacement ductility by 129.14% and curvature ductility by 118.27%.

There are numerous engineering applications where Glass Fiber Reinforced Polymer (GFRP) composite tubes are utilized, such as desalination plants, power transmission systems, and paper mill, as well as marine, industries. Some type of machining is required for those various applications either for joining or fitting procedures. Machining of GFRP has certain difficulties that may damage the tube itself because of fiber delamination and pull out, as well as matrix deboning. Additionally, short machining tool life may be encountered while the formation of powder like chips maybe relatively hazardous. The present paper investigates the effect of process parameters for surface roughness of glass fiber-reinforced polymer composite pipes manufactured using the filament winding process. Experiments were conducted based on the high-speed turning Computer Numerical Control (CNC) machine using Poly-Crystalline Diamond (PCD) tool. The process parameters considered were cutting speed, feed, and depth of cut. Mathematical models for the surface roughness were developed based on the experimental results, and Analysis of Variance (ANOVA) has been performed with a confidence level of 95% for validation of the models.

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.
