This article takes a single-tower cable-stayed bridge with steel-UHPC composite deck steel box girder as the research object and develops different casting plans for UHPC layer on deck. It analyzes influence of factors such block sequence deck, whether or not to set up post-casting section, counterweights range it additional deformation stress formed during construction stage, exploring impact ...

Abstract: Fatigue fracture of bridge stay-cables is usually a multiscale process as the crack grows from micro-scale to macro-scale. Such a process, however, is highly uncertain. In order to make a rational prediction of the residual life of bridge cables, a probabilistic fatigue approach is proposed, based on a comprehensive vehicle load model, finite element analysis and multiscaling and meso...

The road and railway infrastructure in Poland has been intensively developed and modernized for the last years. Around 300 new bridges are built annually. Among the new structures, there is a group of modern extradosed bridges. This paper presents examples of short-, medium-, and long-span extradosed bridges designed and built in recent years in Poland. The following structures are described in...

In this study, new-type hybrid faring is suggested to improve the aerodynamic performance of long-span cable-stayed bridge. The proposed fairing developed by applying concept multibox section normal faring. has void regions inside so that wind passes through gaps in As a result, flow changed and forces bridge are reduced. efficiency was verified series tunnel test. From test it can be found per...
