    Shed Dormer on House w/ Exist Gable Dormer

    Based on the age, I assume the roof decking is plank. Is that correct? If so, how close are the planks to each other?

    Shed Dormer on House w/ Exist Gable Dormer

    I am trying to picture the original load paths since you will be altering that by any modification. Does the right side currently have a stiffleg near the brick wall like the left side? Is the stiffleg isolated to the hip rafter or is it part of a kneewall? What do you know about the floor...

    Shed Dormer on House w/ Exist Gable Dormer

    If the existing hip rafters or the hip jack rafters have vertical supports for them, they are most likely holding up the main ridge where the front dormer ridge frames into it. If they do not, then I am surprised that everything is currently intact unless you are not in an area with a...

    Shed Dormer on House w/ Exist Gable Dormer

    I never like answering something like this without a fairly clear idea of what is proposed. So here it goes. Is the picture the concept of the final product or the existing condition? How are you going to "anchor" to a brick wall? How is the brick wall built? Plan view of existing framing...

    Learning Structural Connection Types – Pin vs Fixed (Real World Example)

    Thanks, I noticed it at the last minute and from that point forward, I was confused. Then I saw 3 lanes, and 3 different Yield signs (I think). I actually thought it was a 1-way street. Dang-it, now I have to change my FE model to metric since it is AU!!

    Learning Structural Connection Types – Pin vs Fixed (Real World Example)

    Is this the famous bridge that trolls stay under? Looks tall enough for trolls but no one in the NBA. Am I missing something about the direction the sign faces? Looks like the sign info is on the far side but traffic also looks like it drives under the sign AFTER it has gone under the bridge...

    Learning Structural Connection Types – Pin vs Fixed (Real World Example)

    I think it is the last one, but I feel more comfortable building a Finite Element model before I commit. Is it safe for me to assume the temperature will be constant in the model?

    Learning Structural Connection Types – Pin vs Fixed (Real World Example)

    Since your column is a W-shape (I-shape), the anchor bolt location that "restrains" the flange is an indicator it is fixed. Had they wanted it to be pinned, the anchor bolts may be located in between the flanges closer to the center of the web. The fact the entire structure is unstable UNLESS...

    Cracking in Wood Joists

    By chance, did you probe the wood looking for signs of wood destroying fungus? Advanced WDF is easier to spot than mild to medium degradation. I would probe a few joists looking for indications of it. That loss of strength due to WDF can cause any sag to become worse. I have had several...

    Cracking in Wood Joists

    I would rather argue they deceptively changed to those words 50 years after releasing the song, than truly admit I was wrong all those years.

    A Conceptual Modification to the Continuing Education Requirements

    Many thanks for the clarification. I am not sure how you are using "hypothetical" but if you mean not 100% accurate, I agree. Those courses do teach basic fundamentals with "some assumptions", not "imagined" fundamentals. If you are using it as "imaginary", then I disagree. I was not taught...

    Loft Reconfiguration

    The most common modification I know of is to install a ridge beam in place of the ridge board as you note. How far will this modification extend into the length of the house? Interior walls that are parallel to the roof framing offer ties periodically although most people do not rely on them...

    A Conceptual Modification to the Continuing Education Requirements

    I had someone I worked with like that. When I tried to teach them the few different lumber sizes (2x4, 2x6 etc), they said they could never remember all that. They could, however, cite about EVERY piece of info on his favorite college football team's players. Name, position, high school...

    Cracking in Wood Joists

    I agree with sistering as a solution. Is there a grade stamp anywhere on the lumber? I remember some small local sawmills in the 70s and 80s that made lumber with no inspection, grading or seasoning. Some people wrongfully used it for houses although it was mostly intended to be used for...

    Temporary Plate to Hold Anchor weight

    What is the price of failure? You most likely need a local engineer as JAE suggests. While this website is a really good source of new ideas, old ideas and methods, rarely does anyone give you a final answer in terms of a design. For any of us to do that would be irresponsible. Final designs...

    A Conceptual Modification to the Continuing Education Requirements

    Most of mine only allow you to roll over from the previous year and many limit the hours. A 3-year cycle coupled with more roll-over hours would be a vast improvement. As you state, it allows for a bigger time investment on a single subject you may really want or need. I saw the record...

    Valid Pin Boundary Condition?

    Most people I know would design this as pinned but they would consider that the baseplate and foundation design can affect where along that transition from pinned to fix occurs. Really thick baseplate coupled with a wide and thick foundation moves the needle closer to fixed while the thinnest...

    A Conceptual Modification to the Continuing Education Requirements

    Did you make a time capsule somewhere in the past? I think that is where my "girl-watcher" sunglasses are at. Can't sing the song, if you don't wear the glasses.

    Steel-to-Steel Fastening with total thickness greater than 1/2"

    Someone wanting to use cheap and generally untested fasteners is still something that really bothers me when they propose it. I have never seen the requested substitution pan out unless the alternative is also a premium fastener. I call them "Carnival Bolts". Go to the carnival, pay someone...

    Thin stair concrete design

    From what I have seen, most paints generally won't look that good for 25 years. Have they considered some of the newer concrete appearance finishes I have heard of. Never used any, but have heard of them.
