Critical Buckling Load Calculation Method of Nuclear Grade Dynamic Tension Bars

In this paper, the critical buckling loads of these non-uniform section bars are checked by using a quick and effective theoretical calculation method to meet the engineering application. Transfer matrix method used in this method is checked by using the finite element and KTA3205 test method. The differences of these results are analyzed to verify that the theoretical calculation is reasonable and usable by comparing with the manufacturing process and the simplified calculation method.
