The aim of this thesis is to provide rational engineering methods for the fatigue safety examination of existing railway bridges. Increasing railway traffic loading and enhanced structural analysis allow for higher exploitation of the capacity of bridge el ...
The promotion of tubular structures in bridge construction is a meaningful goal since these are aesthetic, lead to structurally efficient systems as well as sustainable ones. Good fatigue design of the tubular superstructure is a key factor to ensure safet ...
Steel tubular truss are lightweight, aesthetical and used in many different applications. These structures are sensitive to fatigue and specific verification methods have been developed for them, in particular by CIDECT [2001]. Due to assembly and welding, ...
With the occurrence of higher and more frequent axle loads, bridges are more solicited by fatigue loading. Bridge elements like deck slabs are subjected to a high number of stress cycles at relatively small stress magnitudes. The application of Fracture Me ...
Due to ever increasing traffic demands the fatigue safety and service life of the bridges of a railway line in Brazil need to be examined. Conventional assessment methods using load models and approaches as suggested in codes lead to conservative results r ...
New load-bearing structures made of fiber-reinforced polymer (FRP) composites comprise
adhesively-bonded joints, which are components vulnerable to fatigue failure. These
structural components are frequently subjected to complex cyclic loading histories ...
The influence of welding tensile residual stresses on fatigue crack growth in bridge tubular K-joints is investigated through experimental testing of large-scale specimens. Crack development is monitored using the alternating current potential drop method. ...
Seeking light and transparent bridge designs, engineers and architects have found an efficient and artistic way to fulfill their requirements: steel tubular bridges. In these modern tubular truss bridges, welded K-joints have been shown to be critically su ...
A critical aspect in the design of tubular bridges is the fatigue performance of the structural joints. Economic viability depends on it. Lower fatigue strength for joints with thicker failing members was observed in welded joints typical to the bridge app ...
Welded circular hollow section (CHS) joints typical to bridge construction have been examined in an experimental, numerical, and analytical study with respect to their fatigue strength. Evidence from this study has indicated lower fatigue strength for join ...
