Comparison of Behaviors of Jointless Bridge according to Depth of Abutment Among Numerical Models
Journal of the Computational Structural Engineering Institute of Korea, 2022 This study investigates the behavior of a jointless bridge that integrates superstructure and abutment without an expansion joint. Based on the sensitivity analyses conducted in previous studies, a shell-based model was determined to be the most suitable

Environment-Induced Performance of End Concrete Diaphragm in Skewed Semi-Integral Bridges
Buildings, 2022 Past research has shown that as skewed bridges change temperature, additional lateral movement or forces will occur along with the elongation of the bridge. Even though past research has documented this behavior, lateral movements of semi-integral bridge

Structural Concrete, Volume 24, Issue 2, Page 2563-2574, April 2023., 2023 Abstract Deck caps of bridges—in Germany shortly known as “bridge caps”—are usually made of steel reinforced concrete to form the anchoring area for the guardrail of bridge deck edges on existing cantilever slabs. Combined with protective devices, the outside arranged deck caps provide safety against lateral breaking or crashes of vehicles.

Civil Engineering Design, Volume 3, Issue 5-6, Page 210-228, December 2021., 2021 Abstract Limiting crack widths to an acceptable level and determining the required minimum reinforcement are important tasks in the design of reinforced and prestressed concrete structures. Experience with different types of structures, ranging from watertight concrete structures to prestressed concrete bridges, shows that the concept currently applied
