3D FE analysis of four legged jack-up vessels during preloading in cohesive soil

Since the exploitation of wind as a renewable energy resource, jack-up vessels equipped with more than three independent legs are increasingly employed to transport and install the components of offshore wind turbines. By lowering the movable legs the vessel is able to elevate the hull from sea water level. In elevated position the vessel...

Fatigue assessment in finite element analysis: A post-processor to FEA output for hot spot stress calculation

For the fatigue assessment of welded structures, several design methods are described by the design codes of IIW, Eurocode3 and DNV. The relation between the stress range and cycles to failures were derived from experiments: the SN curves. With the increased accessibility of finite element software to engineers, a more flexible approach emerged:...

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...

Feasibility study on fiber reinforced polymer cylindrical truss bridges for heavy traffic

Considering the recent increase in the use of fiber reinforced polymers in the civil engineering industry in general and in the bridge engineering industry in particular, as well as the recently more and more applied cylindrical truss bridge type, this research focuses on the question whether it is possible to combine fiber reinforced polymers...
