Designing for fatigue is very different than designing for static loads. One of the biggest challenges is being able to estimate the loads, timing of the loads and duration of the loads. If you look at a bridge you have to estimate the number of vehicles going on the bridge every day, the weight of these vehicles, and other forces and loads acting on the bridge such as its own weight (steel and concrete), wind loading, and pre-existing stresses such as those caused by welding. Four of the main factors that will affect the fatigue life of a welded structure … Continue reading Welding fatigue assessment
New European Standards – EN 81-1 EN 81-2 Almost 3 years ago, new European standards for the design, manufacture and testing of lifts were introduced. The standards apply to both passenger lifts and passenger goods lifts and come with the catchy names of EN81-20 and EN81-50.
