Abstract
In order to study the preparation and properties of HFRP bars for civil engineering, this paper, through experiments on the tensile and fatigue properties and fracture analysis, analyzed the tensile and anti-fatigue properties and preparatory processes of HFRP bars. Results showed that the HFRP bars specifically for civil engineering integrate the pultrusion and winding processes, concluding that high-strength GFRP bars have high fatigue resistance, and the fatigue damage of high-strength 4# GFRP bar is less at the maximum stress of 33.8% and the stress amplitude of 7.5%.
