Effect of section geometry on development of shrinkage-induced deformations in box girder bridges [PDF]

, 2017
Non-uniform shrinkage strains can lead to significant additional deflections in large box girder bridges, leading to serviceability problems. This article examines experimentally and analytically the effect of different cross-section geometries on the ...

Bridge deck analysis of transversely post-tensioned concrete box girder bridges

Electronic Journal of Structural Engineering, 2023
For rural bridges in Australia, a common design practice is pouring in-situ concrete on top of beams in order to tie all the beams together and distribute load. However, pouring concrete on-site creates more risk and contractors prefer to avoid it. Another method is using transverse post tensioning to tie beams.

Structural performance evaluation of a precast PSC curved girder bridge constructed using multi-tasking formwork [PDF]

, 2016
Recently, advanced transit systems are being constructed to reduce traffic congestions in metropolitan areas. For these projects, curved bridges with various curvatures are required.

Load Distribution Factors for Horizontally Curved Concrete Box Girder Bridges [PDF]

Engineering and Technology Journal, 2014
In this study, a 3-D finite element model was used for the analysis of the horizontally curved bridge slab built monolithically with box girders. A parametric study was carried out to calculate the load distribution factors for horizontally curved ...

Bridge-specific fragility analysis: when is it really necessary? [PDF]

, 2018
In seismic assessment of bridges the research focus has recently shifted on the derivation of bridge-specific fragility curves that account for the effect of different geometry, structural system, component and soil properties, on the seismic behaviour ...

Experimental Study and Numerical Analysis of Hydration Heat Effect on Precast Prestressed Concrete Box Girder

Buildings
Large-span precast prestressed concrete box girders have been widely used in bridge construction near or across the sea. However, this would easily lead to a hydration heat problem, including large initial tensile stress and concrete cracks during the ...

Covariance Structure Modeling of Engineering Demand Parameters in Cloud‐Based Seismic Analysis

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Probabilistic seismic demand modeling aims to estimate structural demand as a function of ground motion intensity—a critical stage in seismic risk assessment. Although many models exist to describe the structural demand, few consider the covariance among engineering demand parameters, potentially overlooking a key factor in improving the ...
