AISC doesn't give much guidance on this subject. Does anyone have a copy of the ASCE Journal of Engineering Mechanics, February 2001? It contains a paper on the subject by Ali Davaran. I would appreciate it if someone could summarize Davaran's conclusions before I pay $30 to buy the article...
For those of you who do a lot of single-family residential projects in the U.S., what is the extent of specifications usually provided?
Do you provide:
A. Only notes on the drawings
B. Full CSI 3-part specification project manual
C. Something in between
Or maybe a better question would be what...
I'm looking at a drawing from 1950 that shows 14SJ5 joists with spans of 14', 16', 18', 20' and 22'. Will someone who has a historical SJI manual help me out with the allowable loads? Thanks.
A project I am working on includes a few guard shacks that are protected from vehicle collision by cantilevered cast-in-place concrete walls. The design criteria for the barrier walls is to be AASHTO Roadside Design Guide 3. As a building engineer, I do not have this reference. Can someone...
For building projects I work on, geotechnical requirements (subgrade compaction, slab base materials, etc.) are usually contained in a soils report that is not officially included in the contract documents that the contractor bids on. Because the soils report recommendations are not written in...
For working stress design, the MSJC masonry code specifies an effective wall width to use in computing compressive stresses due to concentrated loads (Section 2.1.9.1). Effective width does not appear to be prescribed for strength design. Is it left to the engineer's judgment whether to adopt...
Any comments on the pros and cons of hot-dipped vs. mechanically galvanized bolts? The application is statically loaded A325 bolts in a sewage pump station. The bolts will be subjected to constant high humidity and possibly intermittent water contact.
Are there any approved national (U.S) standards for determining wind loads on temporary structures? Say, for example, that during renovation of an existing two-story building, the second floor diaphragm will be removed and replaced. While the second floor is absent, the existing exterior walls...
In my experience, elevator support design forces (hoist beam, guide rail, pit slab, etc.) are sometimes difficult to obtain during the design phase. Some elevator suppliers do not want to give out this information before they have a contract to supply the elevator. That leaves the structural...
Where is the most practical location to set building grids on plan drawings for a wood bearing wall building, and why? Centerline of wall, face of stud (exterior/interior), face of sheathing, other? The building will have both exterior and interior walls.
