Has anyone used a (2) sided high load diaphragm? In this case, say Structural 1 sheathing with 10D nails, (3) lines of fasteners has a capacity of 1,950 plf.
Is it possible to use this on both sides of a wood shear wall?
Have an investigative project. A 2-story wood structure that the owner called and said the second story wall shifted outward from the building. I spent about 2 hours looking at different structural aspects and then decided to look at the trusses a little further after not finding any thing...
I did an investigation into a wood truss failure and am providing a fix (see attached photo for failure). It's an entire section of the roof system that failed at the same connection point...probably about (35) trusses total. The request has been made to remove the deflection in the trusses such...
I got a request from a long term client asking to design hold-downs for shipping containers to be used as storage units. The building department is requiring them to have hold-downs. There are 135 units all smashed together. The contractor does not want to do any welding for hold-downs, which is...
I'm doing a building review for change of occupancy and additional openings. There was a remodel completed about 25 years ago and it appears the lateral system was drastically changed. The designer used wood shear walls on the inside of the CMU. The CMU walls are only acting as bearing walls and...
See attached. I haven't looked at a ramp in this manner before, but the architect is bound and determined to create a cantilevered landing for some stairs. It isn't shown in the detail, but the ramp would turn 180deg and continue up the opposite direction.
Anyone see any issues with this? Other...
Have a bit of an issue that came up with an Architect. The detail they wanted was the CMU going to the bottom of the floor joists as shown in the attached with the joists resting on top of the glulam beams. The problem is, they drew everything so that the free board was 12" between bottom of...
I have been asked to design a 65ft tall pole for a sign. See attached dimensions. They want a break at 25ft, and then another pole break at the sign which is supposed to have a HSS Tube behind the sign for attachment. Does anyone have any ideas on how to attach these together besides a plate...
Due to one of my largest architectural clients moving all of their stuff to REVIT, I'm forced to move my work (at least for them) to REVIT as well. I would say that it is nearly 95% wood construction that we do and buildings from 1-story to 4-stories in height.
Is anyone out there using REVIT...
Working on a pretty simple wood building that was originally a remodel to be a new gym and physical therapy building. Stemwalls and footings, floor joists with crawl space, and wood walls and trusses. Just a small rectangle (5,000 sqft). The original building was built in the 1970's. I actually...
In the attached picture is a local school that has a massive drift on it's low roof. The school was built in the 50's. The roof beams are deflecting approx. 4-6", the wall is bowing outwards...assuming the columns are buckling as well.
Question, is there any "safe" way to shore this sucker up...
Just got through providing details for a single story wood building modification. It is a complete removal of interior and exterior skin to the structural components. In the process, the contractor found extensive rot in this building. See attached images. The beams are all glulam beams. It...
I ran a search on here for log home design and there really hasn't been much since 2006-2010.
I recently was asked to design my first log home. Standard D-log construction. I have designed a lot of custom homes, but not log specific homes. Where does one start with the lateral on this and also...
As part of a new build/TI for a school I need to figure out how to mount a new center hung scoreboard to the ceiling of the existing gymnasium. It's a wood structure with arched glulams and 4x12 purlins. I have checked the capacities and both are sufficient for the added load. The weight of the...
I have a decently unique project that we are trying to figure out loading conditions for. We are designing the structural "shell" for a firewood dryer. It is rectangular in nature, about 30ft tall, 10ft wide, and 20ft long. It will all be built out of steel.
Question: Anyone have any ideas on...
Has anyone ever been asked to justify adding insulation on top of a suspended acoustical ceiling grid? The code allows for 4 psf prescriptive loading to the suspended ceiling attachments systems. Adding insulation is like another .75 psf. An architect I do a lot of work for asked if I could...
This seams like a silly question, but I'm trying to interpret the IRC...never done that before. Attached is a pdf of the wall stud heights for prescriptive design. Under footnote "B", one of the exclusions says that the table is only good if the maximum span for floors and roofs does not exceed...
Has anyone ever designed an indoor trampoline park? I'm contemplating submitting a proposal on one, but am a bit nervous. It seems loads on the columns and beams and such could get quite substantial.
I would imagine there are columns with kickers at a 45deg at the base that goes under the...
What risk category should these be?
Career Tech Building - Pre-Engineered Metal Buildling. This is a building that will be used for learning welding and other trades. Total building footprint is 8,000 sqft. It will have less than 50 kids at a time. Technically it is a school, but does not meet...
I have a school project where we are adding on to an existing school. We are adding enough square footage that I elected not to do any attachments to the existing structure and leave it alone. This week the architect sprung something on me in regards to wall separations. He has to provide a...
