RISExperimental and Simulation Studies on the Mechanical Performance of T-Girder Bridge Strengthened with Transverse Connection
Publisher: American Society of Civil Engineers
Abstract: In this paper, a new method is proposed for the strengthening of a T-girder bridge with a transverse connection. The proposed connection consists of a top plate, two diagonal braces, one horizontal brace, and two brackets. ...
Fatigue Life of Composite Truss Used to Strengthen the Prestressed Concrete Box Girder Bridge: A Case Study
Publisher: American Society of Civil Engineers
Abstract: The study assesses the fatigue life of a composite truss (CT) employed in strengthening the Xiuzhen River Bridge. Initially, weigh-in-motion data of the bridge undergo analysis, focusing on parameters such as traffic volume, ...
A Novel Model for Shear Strength Prediction of a Steel–UHPC Composite Structure Considering Interface Friction
Publisher: American Society of Civil Engineers
Abstract: Existing studies have shown that the interface friction force positively affects and improves the shear behavior at the stud-connected steel–ultrahigh performance concrete (UHPC) interface. However, the effects of the ...
Vibration and Deformation Monitoring of a Long-Span Rigid-Frame Bridge with Distributed Long-Gauge Sensors
Publisher: American Society of Civil Engineers
Abstract: Ambient vibration tests and analyses of a long-span rigid-frame bridge were conducted using distributed long-gauge fiber-optic sensors. The concept of a long-gauge fiber-optic sensor and its merit to reveal local and global ...
Mechanical and Electromagnetic Shielding Properties of Amorphous FeSiB Ribbon–Reinforced Gypsum Composite Board
Publisher: American Society of Civil Engineers
Abstract: Gypsum-based composite boards reinforced with mono- and multilayer perforated amorphous Fe78Si9B13 ribbons were fabricated by pouring gypsum slurry directly into molds with prelaid epoxy-resin-coated amorphous ribbons. The ...
Structural Behavior and Load Distribution Factor of a T-Girder Bridge with Various Truss Diaphragms
Publisher: ASCE
Abstract: A diaphragm is an essential component of a T-girder bridge. Evaluating the influence of various truss diaphragms (TDs) on the structural behavior and load distribution factor of T-girder bridges assists in bridge design ...
