Bump

The length of the beam is 7.3m long so needed splicing to be able to get it into the building. We originally took a wall out that supported the rafters mid span so had to install the beam and structural wall anyway to support the rafters again. The half vaulted ceiling was an after thought.

Thanks for the reply Mark. There is the same setup on the opposite side. A steel beam with a Structural stud wall supporting the roof. The stud wall supports are Approx 1m from the ridge of the roof on each side. Does this mean the rotation is less likely to occur? I have requested it in writing.

Hi All, We have a 1970s bungalow with a traditional cut roof with ridge board. The rafters are supported mid-span via a structural stud wall in 8x2. This consists of a top and bottom plate with uprights under each rafter, all in 8x2. The stud walls are sat on steel beams. Now we had some ceiling joists that were removed following advice from the structural engineer so we could achieve a vaulted ceiling. To our surprise, the engineer later said these may have been stopping roof spread and he hadn’t realised they were tied in to the rafters. Following this, he stated he had advice from a second engineer that stated we shouldn’t need a form of tie as the structural stud wall is acting as a purlin and the roof span is theoretically split in half. So, our question is do we actually need to tie the rafters in? Pictures for reference. Thanks in advance!
