One of the most important aspects of finite element modelling is the mesh design. Strain gradients across first order elements are linear, which means if the mesh used is too coarse then complex areas of the structure are not modelled accurately. If the mesh size is too small however, the number of constraints within the model will increase, this reduces deformations and increases computational costs. To achieve a successful model it is essential to vary the mesh size in certain areas, this mesh refinement should take place in regions such as compression zones and other areas of complex behaviour. Figure 1 shows the mesh layout from a modelled beam-column connection specimen, an enlarged view of the joint area is also given
