Research Advances of Bamboo-Steel Composite Structural Members

摘要

This paper presents a new type of lightweight composite structural system using bamboo-based panel and cold-formed thin-walled steel. The bamboo-based panel and cold-formed steel C-section, U-section or profiled steel sheet can form various bamboo-steel composite members, including composite slab, composite wall, composite beam and composite column, utilizing structural adhesive or adhesive-screw hybrid joins. The paper summarizes the section design, mechanical experiments of the bamboo-steel composite structures based on the application of bamboo-based panel in modern building structures. The research shows that the two materials can form a perfect composite section and the connectionisms are very effective in a long time; these composite members have higher capacity, good stability and ductility. The authors put forward simplified calculation methods for capacity and deformation of these composite members based on superposition theory or transformed-section method. Finally, further research need for bamboo-steel composite structures are suggested including the improvement of global stiffness and analysis of interfacial slips.
