DEVELOPMENT OF PC TRUSS BEAMS WITH CYLINDRICAL CONTINUOUS FIBER REINFORCEMENT DIAGONAL

Abstract

In this study, the fundamental properties and mechanical behaviors of cylindrical mortar members reinforced by fiber sheet were examined. This member has compressive strength of 159MPa and tensile cracking strength of 27MPa. This high-strength member was used not only as compression diagonal member but also as tension diagonal member of PC truss beam, and then the loading test of PC truss beam was carried out. These high-strength members worked well as tension diagonals until the maximum load, and PC truss beam showed the ductile behavior even after the break of some tension diagonal members.
