Two of the most widely used methods for the fatigue life prediction of composite materials under variable amplitude (VA) loading patterns are presented in this chapter. The first method is based on the theoretical formulation and use of a damage summation ...
Being good structural replacement for other conventional material, the pultruded glass fiber reinforced polymer (GFRP) profiles are being increasingly used in civil engineering structures. The connection between components is considered the most suspect ar ...
[4 + 1] Cycloaddn. of alpha ,beta -unsatd. imidoyl cyanide (2-cyano-1-azadienes) with isocyanides in the presence of a catalytic amt. of AlCl3 afforded polysubstituted 2-amino-5-cyanopyrroles in good to excellent yields. In combination with the IBX/TBAB-me ...
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 ...
A new computational tool for the fatigue life prediction of composite materials, designated CCfatigue, is presented in this paper. This new software has been developed based on a well-established phenomenological fatigue life prediction methodology. It is ...
Axial tension-tension fatigue experiments were performed on pultruded glass fiber reinforced polymer (GFRP) plates in a laboratory environment. Different full-scale specimen shapes were examined: plate strips as-delivered, plate strips with tabs and plates ...
Fatigue tests were carried out on welded circular hollow section K-joints typical to bridges. The tests specimens were large-scale (approximately 9 m long and 2 m high) trusses loaded in the plane of the truss. Measured member stresses showed that a signif ...
Following ICOM’s participation in the redaction of a new recommendation for the evaluation of existing railway-bridges, in collaboration with the SBB/CFF, new questions have been raised. Among those, the influence of a welded longitudinal attachment ends s ...
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 ...
Tubular space trusses for bridge applications use thick-walled tubes. The reduction in fatigue resistance due to geometrical size effects is thus an important issue. In order to carry out a thorough study, both fatigue tests on large-scale specimens and ad ...
