Description

Experience Level: Expert
I need assessment/advice by a structural engineer on the following:

Task:
A skylight window has been installed without doubling the vertical rafters. A structural engineer’s advice is sought for to decide if the window can stay as it is, or the rafters need to be reinforced, and over what length.

Attachment:
Technical drawing and measurements about the roof.

Details:
- The rafters are 400mm apart, 38x100m in diameter, and 3m long between the two support point.
- The window is installed mid distance between the support points (bottom and top at 1m-1m away from support point).
- By cutting through one rafter in the middle, the window fits perfectly between two rafters with center at 800mm apart. Horizontal noggins have been applied.
- The window weighs 30 kg.
- The tiles weigh 75kg/m2.
