| dc.description.abstract | The effect of prying action in endplates tends to increase the tensile load that is transferred to the bolts and therefore its effect should be evaluated. The aim of this thesis is to study the effect of prying action on the tension resistance of beam-to-column connections and the scope was restricted to end plate connections for which the collapse was governed by the tension zone idealized by T-stubs. Where there is deformation, no matter how small, there is bound to be a prying force created. The question is whether or not the connection fails because of it. And this is based on the capacity of the bolts to carry the additional force and the capacity of the flange to not form a mechanism and fail. 30 finite element models were modeled and studied to study the effects of four variables on the generation and amount of prying force. From this analysis, it was found that the thickness of the flange, yield strength of the bolt, yield strength of the flange and the distance between the bolt axis and the root of the profile have a -43%, 37%, -4% and 16% contributions to the prying force generated. It was found that for thin flanges, using low yield strength bolts resulted in lower prying force than using high yield strength bolts and for thick flanges, using high yield strength bolts resulted in higher prying force generation than those with lower yield strength bolts whose prying forces were minimums, even zero. The studies also revealed that the best and optional combination to yield a minimum, even nonexistent, prying force and minimum deformation were thick flanges with low yield strength bolts. | en_US |
