| Research Abstract |
In order to examine how structural adhesives could be utilized in steel construction, a total of 65 double-splice tension coupons were constructed from two types of adhesives and with various splice proportions. With one of the adhesives, the coupon strength increased with splice length to the point where the splice strength exceeded the yield strength of steel. Three out of 50 specimens exhibited a 25% lower strength owing to the fact that they were governed by interfacial failure rather than cohesive failure. In contrast, with the other adhesive, the coupon strength did not change significantly with splice length and coupon failure was governed entirely by interfacial failure.
