hello All: I had always assumed that a single plate connection to column web (with a> 3.5") is an "extended configuration" per AISC as the bolt line is typically more than the AISC stipulated value of 3 1/2" and one cannot ignore eccentricity when considering the bolt strength. However, when...

Dear All: I have been licensed as an SE in the state of Illinois since 2006 and now wish to obtain an SE license from the state of California. My review of the licensure board of California's website indicates that I have to give the new SE - Gravity and SE - Lateral exam before I give the...

Dear All: Please direct me to popular references for "Pipe Rack Analysis/Design". I will soon be involved in designing a pipe rack for a steam pipe and want to get to know the things I should be wary off apart from the obvious. Thanks

Hello All: I am not at all familiar with shoring and reshoring used in concrete buildings and recently was asked this question by a concrete sub in a RFI which goes something like this... "We will be using a shoring system that will allow us to strip the shoring around the shores that will...

I agree with JKW05 ... - LTB of the individual stringers is local to the stringer itself. - If one wants to consider buckling of the stringer+thread/riser assembly+stringer then the geometric properties of the entire stair assembly should be taken into consideration.

Thank you Jike,UcfSe and csd72 ...I will try to work on the stairs with the alternate framing suggestions you all have suggested ... I understand that having the base fixed is a big no no ...
