The influence of thermal gradients in steel columns due to pool fires

During this thesis the fire safety engineering approach has been used to investigate the influence of hydrocarbon pool fires on steel columns. Using a fire curve which closely resembles a natural fire curve the temperatures occurring in the steel have been investigated using a Computational Fluid Dynamics (CFD) model. The model consists of the...

Buckling Behavior of Spirally Welded Steel Tubes

This report deals with the buckling behavior of spirally welded steel tubes. First, an existing analytical solution and the results of an extended experimental investigation are investigated. The imperfections measured during testing are investigated and classified, and methods are proposed to incorporate them into finite element models....
