Hi All,
Would appreciate input on the attached detail sketches. We have a job going through DSA (Division of the State Architect here in CA - for schools) where a detail we routinely use for anchorage was rejected due to the distance from centerline of anchor to the intersection of the...
Hey All,
Just wanted to get some opinions on whether it is appropriate to use the overstrength factor to amplify forces when designing the a podium slab per ASCE 7-16's section 12.3.3.3 on elements supporting discontinuous walls or frames.
The procedure behind the two-stage analysis - that...
Hello, I am looking for any up-to-date references on the design of lagging or more specifically, a horizontally spanning member for a soldier pile retaining wall. This would hopefully include the effects of passive arching with a known EFP, internal friction angle, & cohesion.
I was given a...
For a cantilever retaining wall supported on drilled piers, a Geotechnical Engineer on a previous project stated that the active pressure should be considered over 1x the pier diameter below the depth of excavation - continuing all the way to the bottom of the pier.
On a current project of...
Hello All,
My team is racking our brains trying to rationalize a scenario with the following:
A 5 story-wood building is being designed over 2 stories of concrete. We have a 24" mat slab in the basement and two levels of PT slab above. The depth of the highest elevated level is 12" and the...
In your opinion, may I use an OCCS in SDC D, E OR F using referenced footnote "i" of table 12.2-1 of the ASCE 7-10?
That footnote is specifically labelled as an exception for OMFs in its own section but is explicitly referenced as a footnote for OCCS in the aforementioned table.
Thanks.
I am designing an 18'-0" wide structure that has two beams, spanning 18'-0", column to column. The beams are cold formed C-Purlins (with lips) but they have cold formed corrugated metal decking spanning between the beams with screws to their top flanges. There is no blocking between the beams...
