Steel Beam Calculations for Removal of Load-Bearing Walls

We can assist you if you are looking to remove an internal loadbearing wall to create an open plan kitchen diner, to insert bi-folding doors into your property, or create a through lounge. In certain cases, you may require a steel frame, structural columns or nibs to remain.

As a rule, if the floor area surrounded by four walls does not exceed 70m2, the floor area surrounded by three walls does not exceed 36m2 and structural openings are in accordance with the diagram below, the principles of Approved Document A can be followed. If the floor area and aggregate size of structural openings fall outside of this empirical guidance, then additional supports may be required. It is common practice to design a goalpost to provide the required stability to the building when buttressing has been removed due to large openings into new extensions or the insertion of bi-folding doors. As well as providing you with steel beam calculations we carry out associated pad stone designs on all our steel beam calculation reports. The size of the pad stone is important as it is designed to reduce the stress under the bearing from the beam reaction to an acceptable level. This is dependent on the age, condition and material properties of the remaining masonry. In certain instances, such as older properties, stresses are limited to 0.42N/mm2 and new engineering brick columns or steel posts and new foundations will be required as the loading and stresses on the existing construction would be too great.
