Abstract
Relaxation of high strength bolted joints causes large bolt pretension loss at an initial stage of relaxation. However, the detailed characteristics had not been clarified. In this study, relaxation tests targeting many types of high strength bolted joints were carried out. Then, we investigated characteristics of bolt pretension loss at an initial stage of relaxation by literature search. From these results, we discussed the initial value setting method for relaxation tests in high strength bolted joints.
