RISFatigue Assessment of Steel-UHPC Lightweight Composite Deck Based on Multiscale FE Analysis: Case Study
Publisher: American Society of Civil Engineers
Abstract: A lightweight steel–ultrahigh performance concrete (UHPC) composite deck (LWCD) was developed for alleviating deterioration issues in orthotropic steel decks (OSDs). In recent years, the LWCD has been increasingly applied ...
Static and Fatigue Behavior of Short-Headed Studs Embedded in a Thin Ultrahigh-Performance Concrete Layer
Publisher: American Society of Civil Engineers
Abstract: In recent years, ultrahigh-performance concrete (UHPC) has been increasingly applied to orthotropic steel deck (OSD) bridges. The UHPC layer and the OSD are connected through short-headed studs. This paper studies the ...
Fatigue Performance of a Lightweight Composite Bridge Deck with Open Ribs
Publisher: American Society of Civil Engineers
Abstract: An innovative lightweight composite deck (LWCD) is proposed for steel bridges to avoid premature fatigue cracking. The composite deck is composed of an open-ribbed orthotropic steel deck (OSD) and a thin ultrahigh-performance ...
Structural Behaviors of a Low-Profile Steel Plate–Reinforced UHPC Deck Panel with Longitudinal Ribs
Publisher: ASCE
Abstract: This paper proposes a lightweight low-profile steel plate-reinforced ultrahigh-performance concrete (UHPC) deck panel with only longitudinal ribs as an alternative to traditional bridge decks for long-span bridges. The ...
