Beam behaviour of hybrid steel sections

Although hybrid beams offer many potential benefits, such as savings in material and costs, existing codes of practice contain few guidelines on how to design such members. Apart from the lack of design guidelines, recommendations in many steel design codes apply only to steel grades with specified yield strength less than 460MPa. The purpose of the research was, firstly, to examine the development of stresses and strains within the flanges and web in order to establish how this differs from that in homogeneous members. It was also necessary to investigate the effectiveness of various hybrid combinations (with steels of varying yield strength in webs and flanges), the influence of different width to thickness ratios on hybrid beam behaviour, and the possibility of extrapolating existing design guidelines so that they can be used for higher grade steels.
