COMPOSITE BEHAVIOUR OF COLD‐FORMED STEEL ‐ TIMBER FLOORS

Prediction of Acoustic Performance of Composite Steel Floors

One method of constructing lightweight concrete floors in residential dwellings is to use a trapezoidal profile steel pan as a permanent form for a relatively thin pour of concrete. The resulting structure has enhanced stiffness to weight ratio due to the composite action between the steel and concrete, and the inherent improved stiffness of the profiled cross section. However the floor is stro...

Load-carrying behaviour of steel-to-timber dowel connections

This paper details tests on steel-wood-steel connections with thin dowels carried out at the University of British Columbia in Vancouver, Canada. Connections configurations were selected in such a way that the influence of the main parameters such as dowel slenderness ratio, dowel strength, fastener spacing and end distance and the number of dowels could be studied. An important issue of the pa...

Light Steel-Timber Frame with Composite and Plaster Bracing Panels

The proposed light-frame structure comprises steel columns for vertical loads and an innovative bracing system to efficiently resist seismic actions. This seismic force resisting system consists of a light timber frame braced with an Oriented Strand Board (OSB) sheet and an external technoprene plaster-infilled slab. Steel brackets are used as foundation and floor connections. Experimental cycl...

Structural Tests of Concrete Composite - Cross - Laminated Timber Floors Final Report

Experimental tests of a composite concrete-cross-laminated timber (CLT) floor system were conducted. The floor system was constructed with 5-ply CLT panels (6.75 in. thick) made composite with a 2.25 in. thick reinforced concrete topping slab. Four series of tests were performed using different specimen configurations and laboratory testing methods. Tests included: (1) Comparative one-way bendi...
