Currently the beam is shored with posts on either side of the notch - it has been that way for quite a while. The owner wants to get rid of the posts.
I agree that its testament to the quality of the original construction.

I looked at a late 1960's vintage building that has 40' long vertically laminated wood beams at 12' oc. The beams are made up of vertical plys as follows: (1) ply of 5/8" plywood; (2) plys 1-1/2" lumber; (1) ply of 5/8" plywood;(2) plys 1-1/2" lumber; (1) ply of 5/8" plywood. The total beam...
I'm a bit unclear on deflection requirements for Adhered Masonry Veneers. From what I can determine from both IBC 1405.9 & ACI 530-/ASCE5/TMS402 the requirement is L/600 both lateral and vertical.
Is that right?
Are there variations?
We are working on a retrofit of an existing building. Does any one know of rules of thumb as it relates to reasonable slopes for ramps in a parking garages. The parking will be heated and totally enclosed so ice will not be a problem except at the entrance and exit.
Any one out there have a feel for what kind of snow loads to use for a 150 sf canopy that is an architectural feature on the exterior of a building. The interesting thing is the roof is more like a sunshade than a roof as it is all aluminum bar grate with 1-3/16" spaces between the bars.

I'm trying to get my arms around a reasonable wind load to use for an architectural feature (an awning ? 140 sf) on a building I'm working on. It will be a fabric, to be determined later, it will have an irregular shape oriented in an irregular manner supported by a steel/aluminum framework...
Anyone have any experience with adding to a concrete edge ? The situation is this: we have a 10" PC plank cantileverd out to support a stone fascia that weighs about 55plf. The original detail called for a steel angle welded to an embed plate in the plank to support the stone. For a variety...
I've checked out schedule B - just what I'm looking for. However, I'm confused by the terms, specifically Ss, Sr in the Ground snow load catagory and the 1/10 & 1/50 under hourly wind pressures.
Anybody know what those are?
Thanks again.
Anyone have any idea what Wind and Snow loads in the Halifax area are or where I can get the information? The specific area is Lunenburg, Nova Scotia
As always many thanks
Good Question. For the purposes of this discussion I would say that the chimney is part of the structure the moment frame is supporting laterally. If there was significant independent movement we have another problem to solve.
I'm working on a project with one column of a moment frame embedded in a big fancy decorative/functional masonry chimney. The calculated deflection at the top of the frame/column which is about 34' tall is around 0.9". That drift seems ok to me, I'm concerned about the deflection compatibility...
I'm trying to calculate the torsional capacity of a 7' long box beam light gage header that has a torque introduced by an eccentric brick veneer. Does it make sense to consider the (2) vertical stud sections and (2) horizontal track sections to be acting as a group as a "closed section" ...
Anyone have any advise on when the dissimilarity of steel and aluminum becomes a problem.
I'm looking at a high end residential steel interior stair stringer that wants to have an aluminum extrusion anchored to it. The extrusion is what anchors a glass railing to the stringer. A typical...
Any body have experience with individual helical anchors as bearing support for independent columns?
I've been a little reluctant in the past to consider helical anchors, I guess its the engineer/inertia issue.
I'm working on a small project that has limited space and where a lot of excavation...
