I am hoping that someone can explain to me the strength values for heat affected zone presented in the Aluminum Design Manual Table A3.3 for 6061-T6. The ultimate tensile strength for 6061-T6 is 42ksi for non-HAZ and 24ksi for HAZ. That part makes sense. However, when looking at the yield...
Searching through previous posts on these subjects, I found a lot of great discussion and useful information. Thank you all for your insight. I have maybe a slightly different twist on this subject that has resulted in some (rather strong) differences of opinion in my firm.
Assume you have a...
Have had some technical discussions with colleagues regarding the requirements in IBC regarding anchorage and sliding. Putting aside the argument of whether or not it is a great idea, does IBC preclude you from allowing a structure to slide? Section 1604.9 "Counteracting Structural Actions"...
Hi all, and thanks for reading. I am looking for some thoughts as to how folks apply seismic design requirements to non building structures (ASCE 7 Chapter 15). I'll try to make this as brief as possible:
IBC Section 1613 says "every structure, and portion thereof.... shall be designed to...
I have searched previous threads and have not found an answer to this exact issue. For a detail similar to the attached sketch. Not sure if I attached it correctly so I'll try to also describe it:
Picture a 1 1/2" diameter pipe nested into the inside corner of an angle such that the top of the...
I'm looking for the minimum distance required between the edges of a vessel circumferential weld and a nozzle attachment weld per ASME VIII, Div.1
From UW-14, it would seem that there is no requirement for a nozzle of a size that is out of the scope of UG-36(c)(3). Per UW-14(a), any type of...
I was asked by a contractor to look at a skylight installation in an existing building. He was asked by the owner to install two skylights identical to two others already in place. As he got into the job, he got leary and looked for some engineering help.
I have never seen a roof system like...
Can someone give me a "quick and dirty" way to estimate how deep I would have to embed a post in dirt to resist a horizontal load at the top of the post without overturning?
This is just a stupid little backyard project for the kids. If it was at one of their friends houses, their dad would...
In the northwestern U.S., and presumably elsewhere, where it is popular to use cedar shake roofing, it is common to install this over skip sheathing. Rather than lay down a full plywood diaphragm on top of the rafters, 1x4 or similar boards are run perpendicular to the rafters and are spaced...
Does anyone have a good source for design information for a capstan as used in a winch application (I'm not designing a tape recorder which seems to be the most documented use of a capstan!)
The system in question would have a specific line pull on the haul line, which is then wrapped some...
Does anyone have a good source for finned heat exchanger tubes?<br>
I have an application that requires straight tubes, 5/8" OD x 80" long with circumferential fins. The material is type 304 stainless steel and it must meet ASME Section VIII.<br>
I am located in Washington State, USA...
Has anyone used the structural analysis program called "STRAP"?<br>
I am just looking for something that will do moment frames and other small type analysis, not real complex systems<br>
<br>
Any input is appreciated<br>
