I am currently producing a technical report (topic of my choice) of the structural design of an overhead crane, it is mandatory to complete this to graduate from my program.
The design guides I am using are the CISC Handbook of Steel Construction 10th edition, CISC Design guide for overhead crane supporting steel structures, Whiting Crane Handbook, and CMAA Spec. No.74.
I am having difficulty understanding Clause 26.0 of CISC HSC. This is Fatigue Design Criteria. I am confused about variable n and N. The number of cycles I wish to design for is 2,000,000. This will give my structure approximately 50 years of operation. I am using detail category A, Table 9 of S16-09 HSC.
If anyone could explain to me the process of going through fatigue design I would greatly appreciate it. The mathematics involved in this is not my problem, just the literature of the codes and what variables correspond with the values I have for my crane. |
