Fatigue Load Model Safety: Verifying Reliability for Reinforced Concrete Railway Structures

It was unclear what level of reliability was provided by appliance of the Eurocode load models for fatigue due to train loads, meaning that it might be insufficient. Therefore, it was investigated what the provided reliability is, compared to what is should be. Within this report, the focus is solely on fatigue induced by bending moments on...

Numerical Analysis of Stability of Steel Columns With Thermal Gradients

This thesis studies the buckling behavior of I-shaped steel columns under the effect of thermal gradients. The mechanical properties of steel decay signicantly with increasing temperature. Therefore, in case of a re, the buckling resistance of steel columns is considerably reduced due to the decrease in the modulus of elasticity and yield...

Fatigue of steel lock gates

The Netherlands contains more than 400 hydraulic structures, of which 120 are locks. Inspections carried out since 2010 by Rijkswaterstaat revealed that a number of cracks per lock gate have been found. Based on experience and an evaluation of the photos made during the inspections it is assumed that the cracks occur due to fatigue. At this...
