Application of post-weld treatment methods to improve the fatigue strength of high strength steels in bridges

摘要

Based on the work presented in this paper the conclusion can be drawn, that when applying HSS in composite road bridges the fatigue verification can become the decisive design criteria. An effective use of HSS can be achieved with the locally limited application of post-weld treatment methods on the critical construction details. Especially the post-weld treatment method UIT seems to be very promising.
