Numerical evaluation of the slab effective width in steel-concrete composite box girder bridges

Revista IBRACON de Estruturas e Materiais, 2020
: Bridges are structures built to overcome obstacles and allow continuity of transport routes. In the search for efficient construction systems, steel-concrete composite structures, especially box girder bridges, emerged. The American AASHTO and European

Durability performance of a high‐performance fiber‐reinforced concrete for bridge applications

Structural Concrete, EarlyView.
Abstract This paper investigates the durability performance of a coarse‐aggregate high‐performance fiber‐reinforced concrete (HPFRC) developed as a cost‐efficient material solution for precast bridge applications. A comprehensive experimental program was conducted to assess the resistance of the material to the principal deterioration mechanisms ...

REHABILITATION OF BOX GIRDER BRIDGE

Proceedings of International Structural Engineering and Construction, 2017
A large pre-stress continuous box girder bridge consists of two separate parts, ten spans deck and eight spans deck. The bridge was subjected to multiple airstrikes, which caused several damages. The most serious are the complete destruction of four conductive spans in the ten spans deck, the movement of the remaining six spans longitudinally by about ...

desAIner: Design, Implementation, and Evaluation of an AI Tool for Construction Hazard Prevention Through Design (CHPtD) Education

Computer Applications in Engineering Education, Volume 34, Issue 4, July 2026.
ABSTRACT Construction Hazard Prevention through Design (CHPtD) is widely recognized as a proactive strategy for reducing worker risk by addressing hazards during planning and design. However, its integration into architecture, engineering, and construction (AEC) education remains limited, leaving many students, who represent the next generation of ...

The Multi-Functional Modelling Shear Lag Method for Accurate Calculation of Static Response and Accordion Effect of Improved Composite Box Girders

The Baltic Journal of Road and Bridge Engineering, 2023
The composite box girder with corrugated web and steel bottom plate (CW-SBS) is a kind of improved steel-concrete structures. The design of CW-SBS box girders needs the accurate method to calculate the working response and accordion effect in ...

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

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 7, Page 1533-1551, June 2026.
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 ...

Prefabricated Box Girder Crack's Reason Analysis and Preventative Measures

, 2011
With its good spanning capacity and whole structural stress performance, the prestressed concrete box girder is widely used in modern large-span bridge structures. But, if the construction of box girder prefabricated control is inappropriate, cracks will

Appearance Inspection‐Based Typical Damage Investigation of Concrete Curved Girder‐Type Bridges Subjected to Temperature and Vehicle Effect

Engineering Reports, Volume 8, Issue 5, May 2026.
Technical approach of the article. ABSTRACT This study focuses primarily on concrete curved girder‐type bridges, which are commonly used for urban roads and highways. Over the last two decades, practical experience in bridge engineering has shown that these bridges have unique mechanical and damage characteristics, unlike conventional straight bridges.

Numerical Simulation of Post‐Yield Hysteretic Behavior of Lap‐Spliced Reinforced Concrete Bridge Pier Walls Under Earthquake Loading

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1356-1376, May 2026.
ABSTRACT Reinforced concrete pier walls designed before the 1970s often incorporate lap splice in potential plastic‐hinge regions. Previous experimental tests indicate that most of pier walls experienced post‐yield lap splice failure, necessitating a modeling approach that captures not only lap splice strength but also deformation capacity.
