Flexural behaviour and design of the new built-up litesteel beams

Overview

This study has described a detailed investigation into the flexural behaviour, strength and design of back to back built-up beam made of a recently developed, cold-formed steel beam known as LiteSteel Beam (LSB). Both experimental and finite element analyses (FEA) were conducted to improve the knowledge and understanding of the flexural behaviour and strength of back to back built-up LSBs, and hence this has led to accurate and safer design methods for back to back built-up LSBs.
