Abstract :Normal 0 21 false false false TR X-NONE X-NONE Glass fibre reinforced plastic insert ignore into journalissuearticles values(GRP); structural members are currently being produced successfully by pultrusion and are now used in an increasing number of civil engineering applications. Measurements of the orthotropic mechanical properties of the GRP box section are necessary for use in the numerical modelling of connection. Pultruded GRP structural sections may not possess the dimensions necessary for the extraction of standard length coupons for tensile testing. In this study, initial experimental tests have been conducted using ASTM D3039 specimens to provide the experimental longitudinal tensile properties insert ignore into journalissuearticles values(elastic modulus, Poisson`s ratio, strength); of pultruded GRP box section. The transverse tensile properties have been determined using the proposed short coupon following validation against the ASTM D3039 data.   Key Words : Glass fibre reinforced plastic, tensile test, material Properties,short coupon
