Rubberised concrete confined with thin-walled steel profiles; a ductile composite for building structures

چکیده
Tyre components are high-quality materials, which can be utilised and disposed into construction projects. Despite its high ductility impact resistance, rubberised concrete (RuC) with rubber content has a strength much lower than that of conventional concrete. Previous research shows confinement by jacket material significantly improve the RuC. This paper presents how infilling RuC to cold-formed steel (CFS) sections improves local-buckling-resistance CFS thin-walled sections, resulting composite elements where advantage each cancels out disadvantage another. In this research, RuC-CFS developed tested purpose using them for structural frames energy dissipation capacity under extreme loading conditions, while providing resource-efficiency lightweight recycled materials. To enable long hollow beams columns, experimental mixes designed self-compaction (SCC). The results reveal 35 % (by volume) 3 mm thickness profile (S275 grade) gives best performance adding 19 individual constitute

Steel Concrete Composite Structures: State of Art
The aim of this review article is to examine solutions and challenges associated with composite construction. Structural steel and concrete, each of the two materials can be used to its best advantage and, therefore, composite structures have proved economical in terms of overall cost. Combination of steel and concrete systems has been conceived on the premises that each type of construction of...
متن کاملFolding of Thin-Walled Composite Structures with a Soft Matrix
The paper presents detailed micromechanical finite element simulations of composite materials with soft materials undergoing large macroscopic bending deformation. The simulations allow the study of fibre microbuckling under bending, including the kinematics of the fibres, as well as the strains in the matrix. These simulations lead to a simple analytical model that allows a quite accurate esti...
متن کاملAnalysis of Thin-Walled Steel Sections Filled with Concrete Using Non-Linear Finite Element Method
Being economical and performing well under cyclic loads, steel sections filled with concrete have been widely used in structural buildings. Extensive studies and experiments have been conducted to investigate the influence of different parameters and loadings on the behavior of these structural components. Based on the data available from previous experiments and studies, this paper discusses t...
