This study is to understand the flexural behaviors of hollow core beam using GFRP reinforcing Bar. The ultimate goal of this study is to apply the hollow core slab using GFRP reinforcing bar in a construction site. To achieve this, five specimens is planned and conducted on experimental study. The shape and size of specimen are rectangular shape of cross section with 210mm x 230mm. As a results of test, to add deformed bar in hollow core beam using GFRP reinforcing bar demonstrated superior flexural performance. Therefore hollow core beam using GFRP reinforcing bar is considered appropriate to apply in the field.
