Fatigue Reliability Assessment of Orthotropic Steel Bridge Decks Based on Probabilistic Multi-scale Finite Element Analysis

The orthotropic steel deck (OSD) has been utilized successfully for thousands of bridges worldwide; however, fatigue cracking of the OSD has been observed frequently due to the complicated welded details combined with stresses that can be difficult to quantify, and the uncertainties in fatigue damage accumulation. In this paper, a fatigue reliability assessment method is proposed based on a com...

Fatigue Reliability Assessment for Orthotropic Steel Decks Based on Long-Term Strain Monitoring

A time-dependent fatigue reliability assessment approach is proposed for welded details of orthotropic steel decks (OSDs) using long-term strain monitoring data. The fatigue reliability limit function of the welded details is established based on the Eurocode specifications. Depending on the distribution characteristics of the measured daily equivalent stress range, either the lognormal distrib...

3D-Printing of Meso-structurally Ordered Carbon Fiber/Polymer Composites with Unprecedented Orthotropic Physical Properties

Here we report the first example of a class of additively manufactured carbon fiber reinforced composite (AMCFRC) materials which have been achieved through the use of a latent thermal cured aromatic thermoset resin system, through an adaptation of direct ink writing (DIW) 3D-printing technology. We have developed a means of printing high performance thermoset carbon fiber composites, which all...
