Concrete members historica.ly ha.e used either pre-stressed steel or steel ba.s. In recent yea.s there ha. been a. increa.ed interest in the use of fiber reinforced polymer （FRP） ma.eria.s. However, the flexure beha.ior of a.hybrid system reinforced by the combina.ion of pre-stressed steel a.d gla.s fiber reinforced （GFRP） is still rela.ively unknown. The purpose of this work is to study this. Two sla.s of 100 a.d 150-millimeter thickness, with a.spa. of 2.1 m reinforced with both pre-stressing steel a.d GFRP were constructed a.d tested to fa.lure using a.I 318-11 a.d a.I 440.1 R-15. The concrete ha. strength of 31 MPa.a.d the sla.s were respectively reinforced with 5#4 ba.s a.d 3#5 ba.s. Ea.h sla. ha. 37.41 mm2 prestressing wire with a.fa.lure stress of 1722.5 MPa. The experimenta. flexura. strength a.d deflection of sla.s were compa.ed with their respective sizes theoretica. sla.s. The theoretica. sla.s were either reinforced with pre-stressed steel or GFRP reba.s, or a.hybrid system. It wa. found tha. the hybrid system produces better results.
