Is it possible if λc > 1.2?
Thread Content
When designing a column using the PVELITE software according to the 8-2 design criteria, the following message appears. What should be done? The material is SA517 E. Warning: One or more values of LamdaC exceed 1.2. Please refer to paragraph 4.4.12.2(h) in ASME VIII-2 for more information.
The calculations in this part of ASME 8-2 are derived from CODE CASE 2286; according to that case, if λc > 1.2, this method is not applicable. I looked at several types of instability, and in my opinion, if λc > 1.2, other criteria can be used. This approach isn’t applicable because this theory, or method, assumes that such instability won’t occur
If λc>1.2, then other criteria can be used; but what criteria should be applied?
