For an I beam with a channel cap attached to compression flange, are we supposedly to use the same formular (F4-10) in page 16.1-51 of AISC-13th to calculate its radius of gyration?
If it is the same formular of (F4-10) as for an I beam without channel cap, then for item bfc in the formular...
Hello, everyone,
Our client in Europe brought a very tough question for us to answer, we designed a structure for them based on UBC seismic zone 3. They want to know, what magnitude of Richter scale earthquake it can resist, Richter 6, 6.5, 6.8 or what so ever. In other words, they want to...
I guess I had better to start a new thread not to mix with the previous thread to ask this question.
Please see attached sketch.
Suppose we know that the bracing girder is very weak (negligeable), by inspection, we can take the column as if there were no bracing girder, therefore, the...
Hi, ladies and gentlemen.
Please see attached file, 24 pieces of 20' W10x45 Wide Flange column are formed into a circle ring, every column is subject to a pure vertical load and both its ends are pinned. At its middle location, two 2x2x1/4" angle is welded to its flange to form a bracing...
Does anyone know the exact definition of ground snow load rating? Say, for a 40psf ground snow load area, is it means that a whole year's snow fall accumulation is 40psf, or is means that just one snow fall will reach 40 psf (that will means over 24" snow depth at one snow fall)?
Many thanks...
Need help here Please.
I have got a question on Snow load which puzzled me a long time.
In ASCE7-05, equation (7-3) gives the density of the snow:
Garma=0.13pg+14 but not more than 30pcf
according to this equation, one can calculate the equivalent depth of the snow covered on ground by...
I am not quite familiar with Canada building code. Recently I found Canada building code divide its territory into 7 seismic zones (from 0 to 6), what confused me is that its biggest seismic acceleration (corresponding to the fundamental period of 0.2 sec.) at seismic zone 6 is only 0.32g from...
