WebPrimary beams. The strongest primary beam in the range is the MkII Soldier, with a safe working load (SWL) bending of 38 kNm, making it ideal for falsework table use. Using MkII Soldiers, very large flying and rolling tables can be created without the need for splicing, as all the MkII Soldiers can be joined end to end. WebAnalyse and design composite steel beams at the construction and final stages, including automatic beam and stud selection. Link the beam together if necessary, so that secondary beams load primary beams. Design the beams to the ultimate and serviceability limit states, such as vibration frequency, deflection, beam weight and depth.
