Good evening, I am looking for assistance (paid) in performing a very simple modal analysis of a 4-story steel moment frame using hand/spreadsheet calculations. It is not for a school project, I am a practicing engineer (not trained in dynamic analysis) and am curious how the procedure actually...
Hello all, can anyone direct me to how to purchase a copy of XTRACT software for the evaluation of ultimate PM evaluation of concrete sections by Chadwell and Imbsen? Thanks.
Any thoughts on the compliance with the 2015 IBC about using equations presented in the AISC Specification 360-10 since the specification is part of the code but the commentary is not? Specifically I am looking at using CI3.2 for the evaluation of composite beams with studs.
Thanks for the thoughts. I agree, designing to a strain of .002 is probably not a good idea, my question is why does it seem to be allowed per Section 10.3.3 of ACI 318-11?
I am interested in people's thoughts on designing non-prestressed r/f concrete members using a steel strain of .002 with a corresponding phi value of 0.65 given the requirement of Section 10.3.5 which appears to place a lower limit on the strain to 0.004? Thanks for the thoughts.
