To investigate their adequacy as energy dissipating elements during earthquakes, this paper reports on cyclic inelastic tests executed to determine the maximum strength and ductility of four concrete-filled circular steel piers joined to a foundation detail proposed to develop the full composite strength at the base of these columns. Column diameters considered were 324 and 406 mm, with D/t rat...

Spliced joints are used widely in retrofitting traditional timber structures, especially in heritage conservation applications where as much original material as possible needs to be retained. However, in practice this method is mainly applied based on experience, and there is a lack of understanding and quantification of the mechanical behaviour of retrofitted timber members. This paper presen...

Laboratory scale studies have repeatedly reported high P-retention in slag, a by-product of the steel manufacturing industry. Thus, it has emerged as a potential material to increase P-removal from constructed wetlands (CWs). However, several limitations were highlighted by field experiments, including the high pH of treated water and clogging. We hypothesized that the addition of sedimentary r...

This paper presents an experimental and numerical investigation into the stability of normal high strength steel circular hollow section (CHS) columns. Two cold-formed S700 CHS profiles – 139.7×4 139.7×5 (in mm), were studied in programme, twelve column tests (six on each profile), together with accompanying material tests, performed. The load-deformation histories key results from are reported...

A total Lagrangian finite element FE model has been formulated for the nonlinear inelastic analysis of both composite beams and columns. An accurate rotation matrix is used in the position vector analysis and nonlinear strain derivations. The slip between the steel and concrete components due to the flexible shear connection at their interface is considered as an independent displacement in the...

To study the seismic performance of hollow columns with fiber lightweight aggregate concrete, a quasi-static test on eight concrete under lateral low-cycle reversed loading and axial force is presented in this article. The effects dosage plastic-steel fibers (0, 3, 6 9 kg/m3, respectively), steel (25, 50 75 respectively) compression ratio (0.4 0.6, mechanical properties such as capacity load, s...
