ce/papers, Volume 9, Issue 2-3, Page 791-796, September 2026.Abstract This paper proposes a shear‐deformable Generalized Beam Theory (GBT)–Ritz formulation for efficient buckling analysis of thin‐walled composite beams with unsymmetric layups, where extension–bending–twist coupling renders classical beam models inadequate. GBT is used to generate physically interpretable cross‐sectional deformation modes (global,

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2719-2741, September 2026.ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

Vertical Vibration Reduction of Maglev Vehicles Using Nonlinear Model Predictive Control
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 3, September 2026.ABSTRACT This work presents a novel nonlinear model predictive control (NMPC) strategy for high‐speed Maglev vehicles that explicitly incorporates mechanical suspension dynamics into the control model. Unlike conventional approaches, which often neglect the interaction between levitation magnet and car body motion, the proposed method enables ...

Steel Diaphragms in Prestressed Concrete Girder Bridges; TR-424, September 2004 [PDF]
, 2004 Over the years, bridge engineers have been concerned about the response of prestressed concrete (PC) girder bridges that had been hit by over-height vehicles or vehicle loads. When a bridge is struck by an over-height vehicle or vehicle load, usually the

The nose up effect in twin box bridge deck flutter: Experimental observations and theoretical model
, 2021 For the past three decades a significant amount of research has been conducted on bridge flutter. Wind tunnel tests for a 2000 m class twin box suspension bridge have revealed that a twin box deck carrying 4 m tall 50% open area ratio wind screens at the

Experimental Study on Steel-Concrete Composite Twin I-Girder Bridges [PDF]
, 2020 A large number of steel-concrete composite twin I-girder bridges have been built in both Europe and Japan, but the lack of redundancy has always been a concern in the US and many other countries.

Large‐scale tests of 50‐year‐old prestressed concrete bridge girders
Structural Concrete, Volume 27, Issue 4, Page 6227-6245, August 2026.Abstract An experimental investigation has been carried out as part of the BRIDGE|50 research project, focusing on large‐scale loading tests performed on five 50‐year‐old prestressed concrete (PC) girders. The study aimed at evaluating the structural response of five girders retrieved from a viaduct in the urban area of Turin, Italy, subjected to 4 ...
