A beam on suitable wall bearings and a frame with columns transfer loads differently. The structural engineer selects the arrangement from the building, supports, connections and stability requirements.
A beam between wall supports
A beam can transfer loads to assessed sections of wall. The wall material, condition, bearing detail and construction below influence whether that is suitable. Leaving masonry at each end does not by itself establish adequate support.
A frame with columns
Columns can form part of a frame where the design requires different supports. The connections and base details determine how the members act together. A rectangular appearance alone does not tell you whether a frame has the required stiffness or stability.
A lower member or an extra column
A closed frame includes a lower member; multiple openings may share an intermediate column. These arrangements have consequences for layout, floor details and load transfer. They are possible design principles, not upgrades to select without assessment.
Make room for the supporting structure
A column base may require work below the finished floor. Ask how the proposed system affects foundations, visible columns, headroom and finishes. Compare complete designs and scopes rather than only the price of the steel members.
Frequently asked questions
Is a portal frame always stronger than a beam?
That comparison has no useful meaning without loads, dimensions, connections and supports. The engineer assesses the system for its intended role.
Can the column position affect my kitchen?
Yes. Include units, circulation and clearances in the layout brief so the structural arrangement and room design can be coordinated.
