5 masonry columns were strengthened by Sprayed Glass Fiber Reinforced Polymer (SGFRP) in this paper, and a research of the seismic behavior of them tested by eccentric loading experiment was presented. The failure modes of the strengthened masonry columns were illustrated and strengthening effects of them were discussed. The results showed that the bearing capacity of the reinforced columns increased greatly, and the ductility of them also improved significantly. Comparing the strengthening effects of the columns when the thickness of SGFRP and the number of glass fiber are different, some reasonable reinforce suggestions are proposed.

3 masonry columns were strengthened by Sprayed Glass Fiber Reinforced Polymer (SGFRP), and a research of the seismic behavior of them tested by axial loading experiment was presented. The failure modes of the specimens were described, and the data about the load capacity and deformations of masonry columns strengthened by SGFRP were gathered during the experiment. The results showed that the ultimate loads of the reinforced columns increased greatly, and the deformation capacity and the ductility of the columns improved significantly too. Comparing the strengthening effects of the columns when the thickness of strengthen layer and the length of the glass fiber are different, the most effective and reasonable reinforce suggestions are proposed.

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.
