dig1,
I have already reached out to the state building inspector for the area and am waiting to hear back. We'll see what they say...
EnergyProf,
I am the SEOR and designed the project along with some people under me. The piles themselves were a delegated item and were designed by a third...
I did not see it but someone "under my charge" was on site regularly to observe the work. We are a full service "integrated delivery" type of firm so we have big teams and end up having to rely on our colleagues for construction oversight.
In our being on site and generally tracking the...
Anybody do structural engineering in Massachusetts?
I have been asked to sign the Final Construction Control document for a project where I know that some Special Inspections were never performed. For those who don't know about this affidavit, see here...
I think what they are doing to address the thermal bridge issue is to hold the blocking back slightly and provide a small amount of insulation or FRP between the veneer and the blocking.
What do you see instead of this?
Jayrod12,
In the case of a building with a veneer and wall cavity the window will often be set out beyond the CFMF backup and over the wall cavity. To ensure that there is a solid substrate for the window to anchor to we place a piece of blocking (2x6 or 2x8 usually) on top of the CFMF and...
In my office we often specify windows as a delegated design item and have them supported on CFMF walls which are also specified as a delegated design item.
My question for those of you who have similar experience is this; who is responsible for the design of the blocking between the window...
We are designing a three-story timber frame building with shear walls. The architect has asked that we do not use plywood or osb sheathing for any of the walls for fire-rating reasons. It was proposed to use metal x-bracing straps secured to the studs and plates in lieu of sheathing.

Your example is a good one but you are looking at it the wrong way. The bridge formwork is essentially the same type of system as the soldier pile with rakers, it has only been turned on its side. Instead of soil pressing against the soldier pile, you have concrete pressing on the form. The...
Thanks for the response. I agree that it is not likely, but for different reasons (i.e. weight of wall, friction on lagging, friction on pile, etc.). If you draw a simple free body diagram of the system you can see clearly that the compression force in the raker requires a tension force in the...
We are designing a retaining wall for support of excavations in Manhattan. the wall will consist of soldier piles with rakers and wood lagging. The bedrock is very shallow, so the soldier piles are being socketed a few feet into the rock. Due to the steep angle of the rakers, there is a large...
I am using SAFE V12 to analyze a two-way concrete floor slab. The default creep coefficient is 2, but I am not sure if this is correct. Is the creep coefficient the same as the deflection factor in ACI 318 9.5.2.5?
