Hello Fellow Eng-Tips folks,
I have a footing I need to put right next to an existing basement wall. I have read the few posts there are, but alas none are really similar to this condition. This is a small house bump out (about 6ft x 25ft) along the entire side of the house. Bump out is one...
Hi Fellow EngTips people,
I am now doing residential homes, and need some opinions. No where (that I can find) does the IRC 2015 mention wood diaphragms. Nothing in Floors (Chap 5) and nothing in Roof-Ceiling (Chap 8). There is a reference in Section 804, but that is for cold-formed framing...
Thanks for the replies. The vent is uni-directional and can pass 1.3 mL/min. The enclosure will be rated for IP 69k Ingress protection (The standard says something like 70 deg C water at 1400 psi, at 6” away for 3 mins, no leaks). The end user will clean the enclosure from the outside with...
Hi Fellow EngTips people. OK so here’s the problem. I am working on a thermal transfer problem. I am a mechanical engineer that hasn’t done thermal in a while, but here’s where I’m at…..
A 304 Stainless enclosure approximately 350mm W x 200 D x 900 H. The steel thickness id 1.5 mm. I need...
Some information....
dhengr made some good suggestions regarding modifying the geometry/physical form to aid in the way the truss handles the moment. However,...
The geometry is fixed for several reasons.
1. This is a part of a standard product line. The form and layout are standardized for...
So here is a drawing of the truss I am working on right now. 54'-0" long x 1'-0" high.
Suspended by (4), 1/4" dia 7x19 cable. The ends cantilever 7.5' past the last support points. There really is no lateral bracing at all. Top and bottom chords 1.5" sched 40 (or sched 80) pipe. verticals...
Thanks very much for all the helpful comments. I have modeled this in RISA, but don't have a good feel for the magnitude of the explicit imperfections. When I have done buckling analysis on shells, I did a separate analysis just to determine the magnitude of the imperfection. Here I can only...
Greeting fellow eng'ers
I have a engineering problem that comes up time and time again in our industry, but as far as I know, very few people have proposed a reasonable solution. I need to be able to calculate when a vierendeel truss will buckle out-of-plane.
Context: We manufacture 2-D...
