    Temporary Fencing Requirements

    Does anyone know of any specifications or requirements for the structural design of temporary fencing? I'm working on the review of a temporary fence that fell over and my client is asking if it was properly installed. I understand from my research that no permit is required, but are there...

    Rim Joist - Shear Transfer

    Neglecting gravity.... I guess I can try to break this down in the image below. Shear forces on upper level are tension and compression at ends and shear at top and bottom. Same for the lower level. The shear at the rim will be the shear at the bottom plate (assuming floor and roof loads all...

    Rim Joist - Shear Transfer

    If I were to add LTP4 clips, as shown, at the sheathing joint, do you believe that the shear path would now be through the LTP4 clip and not through the rim truss and the rim would not need to be designed for the full shear force?

    Rim Joist - Shear Transfer

    Aesur, On your 3rd sketch, since the shear goes through the web of the truss, would that truss need to be designed as a drag truss? Alternatively, what if the truss designer did not put a web here and instead I had them install 2x blocking. Then, the truss would not need to be a drag truss as...

    Rim Joist - Shear Transfer

    I have a question for you all about rim joists and shear transfer. Typically, I design the wall sheathing to break at the top of the top plates and then attach LTP4 clips at the joint to transfer the load through the joint. My client, however, wants to place the joint mid-height of the rim...

    Retaining wall at front of garage

    My client wants to put a large retaining wall at the front of a garage and then backfill with geofoam. I will be designing the wall for typical vehicle surcharge loads, but what else should I be considering? I want to make sure I'm not missing anything here...

    Engineering of Condo vs Apartment

    Back when I was an EIT I mainly designed residential structures. Every now and again we'd get a condo or apartment building pass through. From what I remember, the lateral design of an apartment building is dramatically differently than the lateral design of a condo building. For the apartment...

    Structural Engineering Liability - Wetstamp

    Just to clarify, we would not be providing a stamped plan that could be used anywhere. We are providing a single design (unstamped) and only providing stamped drawings/calculations for specific lots at a development. They pay a large price for the design of the house, even though it's unstamped...

    Structural Engineering Liability - Wetstamp

    Hey all, I wanted to provide a follow up. My employer has reached out to their attorney to help answer this question. This is the response we've received. "I spoke with a few insurance attorneys in our office, and the consistent response was that as a practical matter, it is incredibly rare...

    Structural Engineering Liability - Wetstamp

    We would not issue an open ended drawing and calculation set. We would charge a minimal fee for the re-use and produce lot specific drawings and calculations. I believe this is how most new home construction designs work. I'm curious though what a typical contract in this case says? Is the...

    Structural Engineering Liability - Wetstamp

    My firm is working with a home builder on doing new residential design. They have Errors and Omission insurance but I wanted to make sure the contract was written so that I am personally protected. I've been reading that I will be personally responsible in the event that my firm is no longer in...

    Out of Plane Wall Bracing at Floors

    I would like to get some opinions on the attached detail as it pertains to out-of-plane bracing. My client is pushing hard and does not want full height blocking at the floor perimeter so I've come up with the attached detail. Any input would be helpful...

    Shearwall Field Nailing

    Ah ha! I misread that as spacing, which started my confusion on this code statement. Thank you.
