This post was last edited by Robinzhang on 2019-2-12 09:36. 1. What does the large P in the formula for the K2 plane instability coefficient on PAGE 16 mean? This was not found in that chapter. 2. During the calculation for a 7.3 U-shaped expansion joint without reinforcement, it seems that the formula takes into account only the nominal thickness as well as the corresponding forming thinning effect C3; how should corrosion allowance and any underdimensioning of the sheet metal be considered in such calculations?
