Reference number: SCEBE/21SF/005/MK
Cold-formed steel sections have become competitive structural components in modern building construction due to their inherent favourable characteristics over conventional hot-rolled steel members. However, the advantages of these members are often limited due to the presence of perforations. Due to the position of perforations, the ultimate strength and elastic stiffness of a structural member can be varied. There are a number of research projects that have been conducted on the analyses of cold-formed thin-walled channel section columns with perforations subjected to different loading conditions. Based on the outcome of the literature review, it can be said that the strength of a structure is largely dependent on the presence/absence of perforations.
Aim and scope of work
The overall objective of this research programme is to investigate the effect of cold work on the mechanical properties of cold-formed steel members.
• To conduct experimental investigations in order to examine the effect of cold work on mechanical properties of cold-formed steel lipped channel cross-section, including developing test specimens, end supports and to obtain a better understanding of the failure mechanisms under different loading conditions.
• To develop non-linear finite element models that are capable of simulating different failure modes of cold-formed steel sections, using the ANSYS software package.
• To investigate and review major cold-formed steel design codes: AISI Specifications and Eurocode with respect to the efficient design of cold-formed steel sections and propose modifications.
The successful applicant will hold a minimum of a Bachelor’s degree in a relevant subject (UK 1.1 or 2.1 classification). Good understanding and prior experience in Mechanical/Structural Engineering will be an advantage.
Candidates are invited to make further enquiries with the Director of Studies.
