Fatigue resistance of hot-riveted double covered joints with complex lay-out
conference paper
The joints in many old bridges still in service to-date are constructed with hot-driven rivets. The estimation of the fatigue resistance of these hot-riveted joints is a complex problem that many scholars have studied. We previously developed an analytical model to estimate the fatigue driving force based on the joint characteristics, such as the ratio between plate width and rivet diameter.
We demonstrated that an evaluation using this fatigue driving force tremendously reduces the scatter of the test data compared to conventional methods. The method is developed for joints with a straight rivet pattern, where rivets are aligned in rows and columns. In this paper, we study how the model can be modified to cover joints with rivets that are not aligned, e.g. staggered. The model is compared to the finite element method and to fatigue tests from literature with staggered rivets.
A subsequent case study of two complex joints from actual bridges provides insight in the various effects that occur in large, realistic riveted joints.
