    Construction/Engineering Conflict of Interest Question

    Thanks for all the comments! I fully disclosed my business before starting at the construction company. I had done a couple of designs that they did the construction on in the past and always kept in contact. I eventually got my engineering business stable enough that I felt like I could get...

    Construction/Engineering Conflict of Interest Question

    We will be talking with our attorney for sure. Maybe I'm just ignorant to the whole thing, but it doesn't necessarily seem like a conflict of interest unless it's a hard bid job. If the chosen contractor is chosen based off of qualifications (i.e. negotiated work) and I'm not involved with that...

    Construction/Engineering Conflict of Interest Question

    I own an engineering business (2 employees plus me) and also work for a Construction Company doing project management for small vertical construction projects ($2-$8M projects). I started the engineering company 3 years prior to starting work for the construction company. I wanted to broaden my...

    What to do when you discover insufficient drawings?

    No loads provided...in one instance the snow load assumed is 10psf light for the given area and snow load maps (I verified with prior snow load information). Jed: I agree, some engineers do minimal amounts based on budgets...but this engineer has made a habit out of it. Water under the bridge...

    Truss Bearing On Dbl Top Pl

    Okay. I was using flat wise bending with a simple span in the past. I just tried doing a multiple span with (4) spans and it works with lighter snow loads. Thanks for the input

    Truss Bearing On Dbl Top Pl

    I have always specified the attached detail when I have an architect want trusses to span more than about 35ft and ground snow loads are greater than or equal to 25psf. I haven't ever been questioned on it until recently when a contractor was all up in arms (not surprising). When calculating the...

    Dental Office Design Loads

    I like the idea of straight 80 psf. That way I won't have to worry about applying the 100 to only certain areas and going through a zillion load combinations. It's a small clinic so I think I would feel comfortable with the 80 instead of the 100 in the lobby and reception area. The floor will...

    Dental Office Design Loads

    Great! Thank you all for the inputs. I think I will leave my design loads as is and then coordinate point loads of the chairs with the dentist and architect. It seams to be somewhat of a gray area with dental facilities (as it is with other health care facilities that are not classified as...

    Dental Office Design Loads

    There isn't anything in the ASCE for design loads of a dental facility. I just picked up a job for one, 1st story is 2,600 sqft and is where everything takes place, 2nd story is for storage and mechanical and is only about 600 sqft. There are only (5) treatment/patient rooms on the first floor...

    Impact Force on Free Standing Conc Wall

    Thank you

    Impact Force on Free Standing Conc Wall

    I have to design a 5ft free-standing concrete wall. It has to be able to withstand the impact force of a 26,000 lb loader. I'm guessing the loader won't ever be going much more than 5 mph on impact...if it impacts at all. The loader must scoop up "beauty bark" from the sawmill debarker outfeed...

    Wood Truss to Concrete Wall - Out-of Plane Connection

    dhengr: Thank you for the post. That was a good summary and exactly the points I'm looking at. The loads aren't huge by any means. Standard residential (or light commercial) but concrete walls with a foot print around 60x40ish. Loads from the wall due to wind or seismic in the 200-300 lb range...

    Wood Truss to Concrete Wall - Out-of Plane Connection

    The previous section to the above is: ASCE7-10 - 12.11.2.2.1 Transfer of Anchorage Forces into Diaphragm Diaphragms shall be provided with continuous ties or struts between diaphragm chords to distribute these anchorage forces into the diaphragms. Diaphragm connections shall be positive...

    Wood Truss to Concrete Wall - Out-of Plane Connection

    woodman88: ASCE7-10 - 12.11.2.2.3 & 12.14.7.5.2 Wood Diaphragms In wood diaphragms, the continuous ties shall be in addition to the diaphragm sheathing. Anchorage shall not be accomplished by use of toenails or nails subject to withdrawal nor shall wood ledgers or framing be used in cross-grain...

    Wood Truss to Concrete Wall - Out-of Plane Connection

    Not sure about the META. Seams as though the contractor would have to be pretty precise on the truss layout. It doesn't leave much room for error.

    Wood Truss to Concrete Wall - Out-of Plane Connection

    ron9876: Are you talking about the Simp. TC connectors or mudsils anchors?

    Wood Truss to Concrete Wall - Out-of Plane Connection

    RFreund: the concern is both uplift and out of plane loading.

    Wood Truss to Concrete Wall - Out-of Plane Connection

    Thanks for the reply. I have the vertical Simp. connector for uplift only. This is just an illustrative detail for purposes of discussion about perpendicular wall forces. My argument/concern is that the anchor bolt in effect splits the sil plate in 2. You are then relying on the Simp A35 to...

    Wood Truss to Concrete Wall - Out-of Plane Connection

    I'm having a debate with another structural friend over connections of wood trusses to concrete walls. I learned one way and he learned another and I'm not sure at this point which is the "correct" way. I attached a detail of the connection. For out-of-plane wind and seismic forces when...
