Abstract
This paper reports experimental data from a number of short term laboratory test studies. The data have been used to establish and evaluate the structural properties of a small commercial pultruded E-glass/vinylester I-beam (102 by 51 by 6-4 mm). Material properties for the flange and web material were measured in tension and compression. The coupon test methods for strength and elastic modulus properties were simplified from the recommendations in standard test methods without serious loss of performance. Three-point bend tests on full sections of the I-beam demonstrated that conventional linear elastic theory formulae may be used to predict the beam deflections and critical loading for lateral-torsional buckling, provided the moduli in the formulae are those of the section. Experimental data from test studies have been used to show the measured tensile strength of the flange material may provide a good estimate for the resistance of the beam in three-point bending, providing no other failure mechanism has a lower load.
