GFRP-Reinforced Foundation Slab Design for 15 Story Residential Building

摘要

This paper represents the summary of the design criteria and construction details for the GFRP(glass fiber-reinforced polymer)reinforced foundation slab.The idea was to improve the foundation slab durability by using GFRP bars.This included the use of GFRP bars as main longitudinal reinforcement for the foundation slabs which represents the world first application of this type.During the design procedures,several nonstandard issues related to GFRP reinforcement have been solved.The method statement has been created for Construction Company with the consideration of the specific properties of GFRP bars in comparison to steel reinforcement.Before the casting of concrete,strain gauges were attached to GFRP bars and concrete surface to control the strains during the erection and the maintenance of building.
