The thread referenced was interesting and I'm curious of others more recent opinions. For my case consider a residential stem wall extending down to frost depth. Slab on grade on the interior, soil 6" below on the exterior. Frost depth 4'-6", 24" footing, 8" wall. We all know...
I am using LPile for the the lateral analysis of a drilled shaft socketed into bedrock. The pile shear curves show a peak negative shear just at and below the soil / rock interface. I searched this topic on this board and the consensus was that this load is neglected in structural design. I...
I was asked to look at sizing some jackscrews for a compressor skid. Typical skids consist of a steel wide flange fully welded base about 35 ft long x 12 ft wide. As an example we would have 5 anchor bolts on each long side - (10) total with (10) jackscrews placed near the anchor bolts. The skid...
I saw this condition on a recent site visit where the contractor nailed the deck joist hangers thru the exterior OSB sheathing into the LSL rim board. They did not install the 2x ledger with lag screws per the plans. I understand there are issues with flashing and lateral pullout design has been...
I am looking for opinions and current practice for design of wood floor framing with stone veneer on top. I am aware of the Marble institute criteria for L/720 deflection. I understand this to be a total load requirement. Similarly I have criteria out there for tile and stone floors that talk...
Are there any guidelines for supporting a garage floor on stud walls? I have a 19ft x 12 ft. garage floor using 14" LVL's, 1 1/8" plywood and 4" topping slab. We have done wood floors many times and APA has some good tech info on these. I can't find any literature on supporting this kind of...
I review many soils reports with recommendations for drilled piers that include a minimum depth of penetration. Based on various soil layers it is sometimes obvious why the soils engineer selects a particular depth. Other times it is not so obvious and I am curious if this is determined by...
I am designing a foundation for a finger type slug catcher consisting of 36 in diameter pipe. I have done these in the past by using typical friction forces on the support but I have had one client say that a slug catcher moved quite a bit on startup. Prior to design he insisted that there were...
