Behaviour of cold-formed dimpled columns under lateral impact

Behaviour of FRP strengthened concrete columns under eccentric compression loading

This paper presents results of testing eccentrically loaded columns externally wrapped with two types of materials. Six cylindrical (205 mm diameter and 925 mm height) plain columns were cast and tested. Half of the columns were wrapped with GFRP and the other half with CFRP. All columns were tested by applying an axial load at 50 mm eccentricity. In each group (GFRP or CFRP wrapped) of columns...

Behaviour of FRP wrapped circular concrete columns under eccentric loading

Dynamic compressive behaviour of ceramics under lateral confinement

A new experimental technique for imposing lateral confinement on specimens subjected to high-strain-rate uniaxial compression is being developed. A brief description of the experimental technique, as well as some preliminary experimental results of the technique are presented in this paper. The results show that under lateral confinement, the impact strength of a brittle glass ceramic increases...

Lateral-torsional buckling resistance of cold-formed high strength steel rectangular hollow beams

Hollow sections have been widely used for steel structures. Applications of High Strength Steel (HSS) on cold-formed hollow sections lead to thinner and lighter structures. This paper presents numerical investigations on the lateral-torsional buckling resistance of the cold-formed high strength steel rectangular hollow beam. Results from finite element analysis using Abaqus software are compare...

On Cold-Formed Steel Construction

Powder-actuated (also referred to as low velocity or powder-driven) fasteners are commonly used to attach cold-formed steel framing members, usually a track, to a concrete or structural steel support. Although commonly used, their behavior is less well understood than other fasteners such as screws, bolts and welds. The AISI Cold-Formed Steel Design Manual does not explicitly address powder act...
