Influence of the Boundary Conditions on the Seismic Response of Existing Masonry Infills From In‐Plane and Dynamic Out‐of‐Plane Tests

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Despite increasing attention to the seismic performance of masonry infills, their out‐of‐plane dynamic behaviour remains insufficiently explored, particularly under pre‐existing in‐plane damage. This study presents a comprehensive experimental campaign designed to investigate the seismic behaviour of an existing weak masonry infill typology ...

Field Tests and Simulation of Lion-Head River Bridge

Shock and Vibration, 2007
Lion-Head River Bridge is a twin bridge in parallel position. The east-bounded was designed and constructed as a traditional prestress concrete box girder bridge with pot bearings; and the west-bounded was installed with seismic isolation devices of lead

Sensitivity study on accuracy and relevant parameters in numerical modeling of internal tendon breaks

Structural Concrete, EarlyView.
Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐

Experimental investigation on the vortex-induced vibration characteristics of long-span twin continuous steel box girder bridge

Advances in Bridge Engineering
The vortex-induced vibration (VIV) characteristics of a long-span twin continuous steel box girder bridge under varying wind angles of attack (α m ), Scruton numbers (Sc), heights of beam (D = 0.078 m, 0.108 m, and 0.137 m) and layout forms (twin, single,

BIM-Based Trajectory Planning for Unmanned Aerial Vehicle-Enabled Box Girder Bridge Inspection

Remote Sensing
Inspection is essential for bridge maintenance and has been supplemented by the use of unmanned aerial vehicle (UAV) photogrammetry. However, a review of the literature reveals that existing approaches require the intervention of a human operator to ...

Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa

Structural Concrete, EarlyView.
Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.

Prestress and excitation force identification in a prestressed concrete box–girder bridge

, 2017
Prestress force identification (PFI) is crucial to maintain the safety of prestressed concrete bridges. A synergic identification method has been proposed recently by the authors that can determine the PF and the excitation force simultaneously in ...

Vision language models for bridge inspections: A review of applications in image‐based damage documentation

Structural Concrete, EarlyView.
Abstract Automating bridge inspections requires more than detecting individual damage instances. It demands systems capable of describing, contextualizing, and interpreting damage in an inspection‐relevant manner. Conventional computer vision approaches, such as object detection and segmentation, primarily address visual recognition tasks and are ...

Finite element modeling of twin steel box-girder bridges for redundancy evaluation [PDF]

, 2010
textBridge redundancy can be described as the capacity that a bridge has to continue carrying loads after suffering the failure of one or more main structural components without undergoing significant deformations.
