Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods

Structural Concrete, EarlyView.
Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.

Research on the longitudinal movement and influence of restraint parameters of the long-span suspension bridge’s main girder

Frontiers in Materials, 2023
The long-span suspension bridge has suffered from multiple failures of restraints such as supports, dampers, and expansion joints due to excessive accumulated displacement at the girder end.

Optimum design of composite prestressed concrete girder railway bridges [PDF]

, 2012
This paper deals with the formulation of design optimisation of pretsressed concrete bridges. The bridge is of a slab-on-girder type, hence modeled as an equivalent orthotropic plate.

An enhanced analytical model for predicting shear strength in reinforced concrete beams with corroded reinforcement

Structural Concrete, EarlyView.
Abstract This paper presents an analytical model to predict the shear strength of RC beams affected by corrosion within the Level IIb framework of fib Model Code 2020. Corrosion is accounted for by (i) reducing the area of longitudinal reinforcement, (ii) degrading the yield strength of stirrups according to Imperatore's law, and (iii) reducing the ...

Girder Longitudinal Movement and Its Factors of Suspension Bridge under Vehicle Load

Advances in Civil Engineering, 2021
Vehicle load may not only cause vertical deformation and vibration of suspension bridge but also lead to longitudinal deformation and vibration. And the longitudinal behavior is closely related to the durability of the girder end devices and the bending ...
