I was curious if anyone knows the reason that AISC Table 1-1 has multiple sections for an individual beam size. Is it to signify some strength difference or availability?
For example: W36 are listed in two "groups". There is a grouping of W36x135 to W36x256 and a separate grouping for W36x231...
I'm doing some checks to size transverse web stiffeners for a wide flange beam. I was hoping to get some clarification on the web sidesway buckling check. Specifically, I am looking at Cr factor. AISC directs you to select a Cr factor based on the ratio 1.5Ma to My. I can't find a definition for...
Does anyone know of a place where Meyerhof's charts for bearing capacity factors for footings with inclined/eccentric loads have been reproduced or scanned in high quality? I have a copy of his paper but the charts are about 1"x1" and it is difficult to read the labels.
This is the paper I am...
I'm looking to detail circular ties (individual hoops) for a drilled shaft. Shear loads are low enough that rebar is not required for strength.
For AASHTO LRFD 7, I used Section 5.11.2.1 to calculate development length (ldh= 1.25*Ab*Fy/sqrt(f'c)) and considered it a Class C splice (ld=...
I'm working on developing a strut and tie model for the new AASHTO requirements. I have a grade beam between two drilled shafts. The drilled shafts have a fixed connection to the tie beam. It seems like there is a good bit of flexibility in how you choose to model a problem in the strut and tie...
