Hello
I hope to get help with a question about beam support. I will hire a structural engineer for final dimensioning but would appreciate your input to evaluate a proposal for kitchen design.
Conditions:
- Villa in Nacka (snow zone 2)
- Built in 1923
- Four floors with the top floor being an unfinished attic and the lowest floor a basement partly above ground
- Timber frame
In 2004, a kitchen renovation was carried out in our house, where a (likely load-bearing) wall between two rooms was partially taken down and a glulam beam was installed. The kitchen is on the lower residential floor with a finished basement below and two bedrooms above.
The existing glulam beam (yellow marking) has dimensions 90*300*3730. It rests on standing beams at each end. On one side built into the outer wall, on the other side, the standing beam rests against a brick wall/chimney (the chimney on the kitchen side is not in use). The chimney (blue marking) extends 760 mm from the wall.
I am wondering about the conditions to take down another part of the chimney and replace the existing glulam beam with a new, longer glulam beam (red marking). The new length of the beam would then be approximately 4100mm (about 37 cm longer). The ceiling height to the current inner ceiling is 253cm.
My questions:
- Do you see any problems with this provided the new glulam beam is dimensioned correctly?
- What size should the new glulam beam have?
- If it needs to be stronger than the old one, does it automatically mean a higher beam, or can it be strengthened in width?
