Abstract
The combination of high durability concrete and GFRP reinforcement for infrastructure construction in the South China Sea can meet its durability requirements under high temperature, high humidity, high salt spray and high radiation environment. Due to the frequent seismic activities in the South China Sea, it is imperative to study the bearing capacity and seismic performance of GFRP reinforced high-durability concrete components and structures. The authors first analyzed the load-bearing performance of GFRP reinforced highly durable concrete beams and established the correction formula for its load-bearing capacity calculation based on the research results. Then the seismic performance of the GFRP reinforced high durability concrete structural members is studied. The seismic damage of the new structure and components is studied by analyzing the hysteresis curve, skeleton curve, stiffness degradation and other parameters. The time course curves and inter-layer displacement angles of GFRP reinforced high durable concrete structure are studied by adjusting the reinforcement type and concrete type, and finally the seismic performance of GFRP reinforced high durable concrete structure is obtained.
