Hello - we have been using a in-house program written in VBA (with excel) that takes separate PDF's and compiles them into booklets with an automatic table of contents, chapter titles, etc. We'll generally us this to compile calculations packages for submittal. We have having issues with the...
Hey everyone,
I have a job with a brick wrapped cupola. At the case where the veneer sits on the down slope, I'm not sure how to support it. I'm thinking of ripping some blocking to so that my brick angle can sit flat (no bent plate) and I can tie it back to the cupola framing. I assume they...
Hey everyone,
I have a 12' concrete wall I'm designing around a bio retention area. I'm assuming that there will additional pressure on the wall from the water in the bio-retention media. I'm trying to work a back door calc on this is RetainPro. My thought was to set the water table height to...
Hey everyone,
I'm looking at some potential renovations to an existing 1950s era building. The floor system appears to be precast channel slabs (13" and 16" deep and about 3'-2" wide). In some areas they bear on CMU walls. In a few areas they bear on a line of beams made from some type of...
Hey all,
I had an issue come up this week on a some modifications we made to an existing PEMB. Long story short, a new expansion was built adjacent to an existing PEMB. The new expansion has a higher roof. No one considered the new potential for snow drift on the existing roof so we were called...
Hey everyone,
I have a small pavilions structure with CFS scissor trusses bearing on steel beams. The contractor has requested we use a thicker sheathing so we can put trusses @ 4'-0" oc. Using 1-1/8" sheathing I can make the numbers work for my loads (wind is 115 mph ultimate and SDC C)...
Hey everyone,
I've got a project where the architect wants to provide a steel channel above the windows. We discussed welding this channel to the bottom of the loose lintel angles (see below arch section). From a vertical support standpoint, the channel actually helps my angle. I think there...
Hey everyone,
I have a weird condition where I need to cantilever a wood beam under under an LVL girder. The cantilever is about 4' long and forms a overhang for an entry. Due to some framing constraints I'm stuck with trying to tie it to a beam above. I planning on using a Simpson tie (two...
Hey all,
I have a single story building with an interesting entry tower. There is clerestory glass and ground to roof glass for two of the exterior walls. My plan was to provide steel framing in this area. This is about 24 feet tall and the architect is hoping for some relatively small columns...
Hey everyone,
I've got another wood building I'm looking at with a large covered porch/patio. The arch wants to avoid knee braces so I'm looking into doing an embedded wood post. Obviously some people say "no way - you are asking for trouble" but it seems this type of detail has been used with...
Hey everyone,
I've got a wood amenities center I'm designing with a wrap around wood porch. Normally I would provide a CMU pedastal to support the porch posts then span a wood girder between to catch the porch framing. The owner and architect want a stone facade below the porch and are using...
Another separate stair issue,
I've got embed plates to design for a steel stair framing into the edge of a 12" thick two way slab. I'm acting as delegated engineer so the stair is mine - the slab is by others. This is a relatively long monumental stair 18' rise and 33' run in a single span. In...
Hey everyone,
I'm looking at a monumental stair design. The stair spans about 33' measured on the flat and has a rise of 18' total. It's one span with no opportunity for posts and is about 7' wide. I've got some relatively large HSS stringers on each end (HSS16x4). The pans will be at least...
Odd question here - I've been asked to provide the maximum live load an existing mezzanine inside of a PEMB can support using the 2012 IBC. The mezzanine is actually an interior build out that creates some offices and meeting spaces. The mezzanine is the area above these spaces. The walls are...
Hey all,
I've been asked by a client to look at an old timber/concrete deck (?) bridge and give it a load rating. Apparently the fire dept. was concerned their trucks would not be able to go over this bridge and serve the 9-10 houses on the dead end it leads to. Full disclosure, all my...
Hey everyone,
I've got an interior build out I'm assisting with and we need a floor surface raised around 16" to 18" inches (think like a raised access floor). The existing floor is a steel composite floor system (3rd story). My plan was to use light gauge framing with sheathing on top to form...
Hello all,
I'm designing a structure is SDC D with ordinary moment frames. To design the moment connections I'm using E1.6b.(b) which allows the use of the limiting earthqauke force (forces calculated with R=1). Since I'm essentially designing for elastic behavior (R=1) do I need to include the...
Hey Everyone,
I'm looking at at build-out of a 1950 era building with open web steel joists and concrete roof. Unfortunately, there has been a miscommunication and the contractor has cut out the one of diagonals in each joist across the entire building to allow for ducting. The diagonal is near...
Hey everyone,
I have a project where an exterior porch is being added to an existing building. The porch wil be framed with conventional steel beams and columns. I originally designed it as a compsite slab - the spans are not large but I like the studs for getting my lateral loads into the LFRS...
Hey everyone,
I'm working on a wood project with wood roof trusses. Single story - SDC C and normal wind. I have a proch roof with a shallow slope all over the perimeter of the building. I have some plcaes my exterior wall job so my bearing point goes away and I can't make the normal truss...
