Reliability Analysis of Infinite Slopes Subjected to Seismic Loadings Considering Spatially Variable Shear Strength Parameters

open access: yes工程科学与技术
ObjectiveEvaluating seismic slope stability is a critical research topic in the field of geotechnical engineering. Natural soils exhibit spatial variability, with properties varying from point to point.

The challenges of GFRP RC beam design for limit states

open access: yesStructural Concrete, EarlyView.
Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Three‐parameter kinematic theory for shear assessment of reinforced concrete short columns

open access: yesStructural Concrete, EarlyView.
Abstract This work presents a rational kinematics‐based model for assessing the shear capacity of rectangular reinforced concrete short columns. Due to their high stiffness and brittleness, short columns are particularly vulnerable to seismic forces, often exhibiting critical failures.

Deflection‐based assessment of residual prestress in simply‐supported bridges accounting for creep variability

open access: yesStructural Concrete, EarlyView.
Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.
