Structural Control and Health Monitoring, Volume 28, Issue 4, April 2021., 2021 Summary Reliable estimation of wind‐induced displacement responses of long‐span bridges is critical to evaluating their wind‐resistant performance. In this study, two Bayesian approaches, Bayesian generalized linear model (BGLM) and sparse Bayesian learning (SBL), are proposed for characterizing the wind‐induced lateral displacement responses of long ...

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 Split‐type steel box girders are widely used in long‐span bridges because of their good wind‐resistance performance. In the design stage, a simple finite element model is usually established based on the beam element for wind‐resistance design. However, since the irregular cross‐beams and diaphragms in the split steel box girder cannot be virtually ...

International Journal of Rotating Machinery, Volume 2021, Issue 1, 2021., 2021 The gas‐lubricated thrust bearing is widely used in agriculture mechanical systems, and the groove shape plays an important role on the hydrodynamic behavior of spiral‐grooved thrust bearing (SGTB). Although the groove shape may change smaller, it is clear that the hydrodynamic response is very sensitive to the groove parameters.

Comfort Evaluation of Double‐Sided Catwalk for Suspension Bridge due to Wind‐Induced Vibration
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 Buffeting response of a double‐sided catwalk designed for Maputo Bridge was investigated considering wind load nonlinearity, geometric nonlinearity, and self‐excited forces. Buffeting analysis was conducted in time domain using an APDL‐developed program in ANSYS, and the results were compared with the buffeting response under the traditional linear ...
