Thermal Effects on Box Girder Concrete Bridges

open access: yesKey Engineering Materials, 2017
Thermal load, especially vertical temperature gradient, is an important factor that should be considered during the bridge design procedure. In the world, several researches focusing on temperature gradient was made, mostly in USA and China, but only a few analyzed actual temperature gradients measuring at European bridges.

Experimental study on protection of prestressed concrete box girder under vehicle explosion of bridge deck

Structural Concrete
This paper presents a study on the explosion protection of prestressed concrete box girder, which is a commonly used in concrete bridges. The explosion protection tests of four prestressed box beams were designed with 1:5 scale.

Free vibration behaviour of thin-walled concrete box-girder bridge using Perspex sheet experimental model

open access: yes, 2021
Purpose: Curved box-girder bridges offers an excellent solution to the problems associated with traffic congestion. However, owing to their complex geometry, they are subjected to shear lag, torsional warping and cross-sectional distortion, which must be

Nothing-on-road bridge-weigh-in-motion used for long-span, concrete-box-girder bridges: an experimental case study

Journal of Structural Integrity and Maintenance, 2023
Nothing-on-road bridge-weigh-in-motion (NOR-BWIM) leverages the response of an instrumented bridge to identify various aspects of traffic information. This system circumvents many of the current issues with traditional BWIM systems, such as lane closure,

Residual performance and damage mechanism of prestressed concrete box girder bridge subjected to falling heavy object impact

Structure and Infrastructure Engineering, 2022
Extreme vertical impact loading from dropped heavy cargo or falling rocks threatens the safety of bridge structures. The impact behavior and post-impact performance of a multi-piece prestressed concrete (PC) box girder bridge were investigated through ...
