RISGaussian Process Regression–Based Model Error Diagnosis and Quantification Using Experimental Data of Prestressed Concrete Beams in Shear
Publisher: American Society of Civil Engineers
Abstract: To facilitate considering model uncertainty for rigorous reliability/probabilistic analysis, this paper proposed a Gaussian process regression–based (GPR-based) model error quantification framework and applied to shear ...
Optimization of Journal Bearing Profiles With Respect to Stiffness and Load Carrying Capacity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an optimization algorithm for journal bearing profiles with respect to stiffness and loadcarrying capacity and an application example of the same. An analytical approach for finding the optimum is ...
Experimental Investigation on the Residual Flexural Behavior of 28-Year-Old Decommissioned Prestressed Concrete Voided Slab Girders
Publisher: ASCE
Abstract: The residual flexural behavior of semilightweight prestressed concrete voided slab girders taken from a decommissioned 28-year-old bridge near Barrhead, Alberta, Canada was investigated. The residual flexural behaviors ...
Finite-Element-Based Study on Girder Behavior and Load-Sharing of Shear-Connected Multigirder Prestressed Concrete Bridges
Publisher: ASCE
Abstract: This paper aimed to study the girder behavior and load sharing of multigirder prestressed concrete (PC) bridges using an efficient nonlinear analysis tool based on finite-element (FE) modeling. A newly developed nonlinear ...
