Formatted abstract

The socket joined columns behaves substantially different to their continuous counterpart. This project set out to investigate the effect of the joint on the axial load capacity and determine the failure mechanism. Three tests were performed to understand the performance of the joint in three different types of failure. Deflection and applied load were measured throughout the column buckling, bending and squashing tests. Analysis of initial deflection and comparison of ultimate load were made to establish the weakest link in the column.

The results showed the buckling load of a 2.5 metre jointed column was half of that the standard column. And the maximum deflection was up to five-times as to the standard columns. Although there were only 3 repeated tests of each configuration, the results do indicate a trend. As results of this project, the design of the jointed column should take special consideration on the assumed ultimate capacity.
