Structural calculations for a multi-storey steel frame with horizontal T-connections, carried out for the owners’ association on the Wattlaan

For the owners’ association on the Wattlaan, we carried out the structural calculations for an extensive steel frame spread over several storeys. The project centred on a precise structural analysis, with particular attention to the stability of the steelwork and the correct transfer of loads to the foundations. The steel frame consists of several storeys […]

Further causes of collapse under heavy snow loads

In the January 2026 issue of the Dutch journal De Ingenieur, Rob Nijsse, emeritus professor of structural design, identifies snow load as a major factor in the collapse of roofs and other structures. He also mentions other possible causes, such as local snow drifts and the extra load from building services and solar panels. What is striking, however, is what this analysis […]

Removing a column creates a large open space. A section with a widened bottom flange was used for this. See the four photos below.

New lifts in existing town houses

The lift walls perpendicular to the strip foundations are heavily loaded. And this while the strip foundations are already very heavily loaded on paper because of the increased (design) values for variable loads. Without extra measures, the strip foundations are then often overloaded. A practical and economical measure is to spread the load parallel to the strip […]
