Seminar - Eric Yao - Non-Linear Analysis and Design of Perforated Thin-walled Steel Strutures

Wednesday 29 October 2008, 1.10 - 1.55 pm
Civil Engineering Lecture Theatre 3

Abstract:

Perforated thin-walled steel structures are widely used, however, current design guidelines for them are limited to very few specific cases.

The seminar will try to describe a proposed method to develop new design guidelines for this kind of structures by using the Direct Strength Method (DSM) which is a fast and easy design method for cold-formed steel structures, with great potential for complex and optimized cross sections.

Based on the recently developed Isoparametric Spline Finite Strip Method (ISFSM) which has been proved to be an efficient and suitable mechanics-based numerical tool for analysing thin-walled structures with holes, analyses which incorporate both geometric and material nonlinearity are going to be carried out for a realistic prediction of strength that can be used in design.
