This paper presented a new retrofit system for strengthening the stringer-to-floor-beam double-angle connections in a 92-year-old riveted railway bridge in Switzerland, using prestressed carbon fiber-reinforced polymer (CFRP) rods. The strengthening system ...
With the development of new materials and advanced structural analysis, alongside increasing aesthetic requirements, recent years have witnessed a trend toward longer, taller, and lighter footbridges. Different from vehicular bridges, footbridges carry rel ...
The web's local buckling is a major failure type of pultruded glass fiber-reinforced polymer (GFRP) bridge deck subjected to concentrated wheel loads. Three kinds of external actions-that is, in-plane shear force, local compressive force and bending moment ...
The objective of this thesis is to develop knowledge and methods to prevent fatigue failure of bridges. The Fatigue Limit State is investigated from both the demand (S) and resistance (R) side.
The S-part focuses on reduction of uncertainties through monit ...
The immediate application of research discoveries requires a global and exact understanding of the structure under consideration. To gain insight into the complex behavior of structures, numerical simulations are carried out in parallel to physical experim ...
The behavior of reinforced-concrete structural elements under moving loads involves many complex parameters related to material properties, vehicle loading, environmental changes and structural response. It is difficult to generate the real conditions of l ...
The evolution of European traffic, combined with the current works of revision of the Eurocode (CEN250 project 2nd Eurocode generation), represents an opportunity to improve the simplified method for fatigue checks (also known as the lambda method) for roa ...
The Second Dongting Lake (SDTL) Bridge is the longest steel truss girder suspension bridge in China, which has a main span of 1480 m. To alleviate deterioration issues in the orthotropic steel deck (OSD), the steel-ultra high performance concrete (UHPC) li ...
In contrast to the Swiss load model used for new bridge structures (SIA 261), which has roots in a Europe-wide weigh-in-motion (WIM) study and considers the full design life of new structures, the model for existing structures (SIA 269) from 2005 is derive ...
Ultrahigh-performance concrete (UHPC) offers significant potential to address a variety of needs in bridge design, construction, and performance enhancement. Bridge owners have shown willingness to embrace novel solutions that could address specific challe ...
