✦ Synopsis
The behaviour and performance of a family of structural connections made of square hollow sections (SHS) has been investigated in the laboratory and a series of data have been collected and presented in a graphical form. In parallel, a rigorous "nite element model was developed capable of analysing the system of the SHS, the cap-plate, the cleat-plate and its surrounding weld. Evidence of non-linearity and deviation from the classical linear elastic theory led to a more complex numerical solution to "t more closely the experimental data. Hence, a speci"c methodology is presented, as it applies to analyses involving plasticity and large de#ections (deformations). Test results obtained in the laboratory were compared with computed values from the "nite element analysis and are presented graphically in the last pages of this paper. Satisfactory agreement was obtained between recorded and computed strains and displacements. The paper includes extensive discussion of the above results and the conclusions drawn from them. A brief account of directly related future research work is also given.
