    Diaphragm Blocking Interference

    So, I checked with the RedBuilt and told the contractor to cut out the strut bracing where it interferes with the blocking.

    Diaphragm Blocking Interference

    I have a high load 5/8" plywood roof diaphragm with 2 rows of 10d edge nails at 3" oc. The framing is Redbuilt Red-W trusses. The placement of some of the strut bracing prevents the placement of the blocking at the panel edges. In one location this situation happens for 50 linear feet. The...

    Opposite of soil face of a retaining wall

    I have used interior and inside face before but really struggled with what to call it for a site retaining wall. I like "weather face" as well, thank you msquared48.

    Opposite of soil face of a retaining wall

    KootK, That is pretty good. I haven't been able to come up with anything and have heard a few other people stumble when referring to the exposed face as well. I appreciate it.

    Opposite of soil face of a retaining wall

    Does anyone have a good term for the face of a retaining wall that is not the soil face? Thanks in advance!

    Axial Load in a cable due to a perpendicular or normal force?

    Simplified Situation I have two cantilevered steel columns that are spaced apart from one another. I have a steel cable running from column to column. If I apply a load perpendicular or normal to the cable, how do I determine the axial force in the cable? Actual situation I have five...

    SST Twist Strap at Every Roof Rafter?

    Simpson has a new "SWDC" screw on page 184 of their 2013 catalog. You can use one screw from the top plate to the truss or rafter. It is a lot faster than installing ten nails for an H2.5A so we have started specifying those on our projects.

    Lag Screws - Compression perpendicular to grain

    BA Retired, I have attached a detail showing the beam to column connection. My thought in changing the column to a beam was to satisfy your dislike of using a lag screw for withdrawal from end grain and steer you back to my original question about compression perpendicular to grain. Without...

    Wood Gable End

    I have attached a PDF showing some of our gable end details. All the details show a gable truss. The first two details are for a smaller overhang and show the "outlookers" flat. The second two details are for a larger overhang and show the "outlookers" on edge. We use the bracing details when...

    Lag Screws - Compression perpendicular to grain

    BAretired, Let's pretend that the 6×6 column is actually a 6×16 wood beam and I have the same question. Do you have any additional thoughts?

    Lag Screws - Compression perpendicular to grain

    I want to attach a wood beam to a wood column using a lag screw with 12" embedment into the column, not including the length of the tapered tip. I am expecting the lag screw to resist withdrawal only. The beam is a 6×12 DF #1 and the column is a 6×6 DF #1. The lag screw conforms to A307 grade A...

    Schedule 5, 10, and 20 pipe? ASTM A53 grade?

    dlclarkii, I have seen schedule 10 and 20 pipe used on a few residential projects before. I was asked to verify existing member capacity and them members were ok based on my calculations. The pipes had been in place for a few years which obviously doesn't mean they saw the design loads, but...

    Headed Bolts vs Rod with a Nut

    amec2004 I understand and agree on the column base Pin or Fix issue. You said, "It's a bad thing if your anchor bolt calculation counts on head bearing while the bond stress always mobilize ahead of head bearing." My question is why? You said, "What's the point if you calculate your anchor...
