TEST OF ALUMINUM CONNECTIONS,
Abstract
The major objective of the task was to evaluate the compatibility of high-strength aluminum connections with parent members in aluminum deckhouses. Additional objectives were to verify experimentally the design techniques for detail connections used by the Bureau of Ships and to determine the structural response of these connections so that a realistic design to withstand a load of 10 pounds per square inch which is the equivalent of 974 pounds per linear inch on the lateral surface of the columns. Six different types of aluminum members, each with different types of connections, were subjected to uniformly distributed static and dynamic loadings. The configurations of the members were T-shaped, L-shaped, three beam-columns of different depths, and transverse beam-column. The tests demonstrated the significance of buckling failures of aluminum members subjected to static and dynamic loads. The 8and 10- inch beam-columns failed by buckling of the compression flange. Buckling occurred at the reentrant corners of the T-shaped and L-shaped connections. Lateral buckling of the compression flange of the column between the transverse beams occurred; this member was re-designed to correct this lateral buckling and subsequently performed satisfactorily. The mode of failure of the various connections under dynamic loads was essentially the same as the mode of failure during the static tests. (Author)
