Abstract
The actual behaviour of cold-formed steel bracing walls in as-built conditions cannot be fully modelled by general purpose computer package for structural analysis. This is partly because of the complex interactions of the studs with the connected sheathing material. This paper discusses the shear load-deflection behaviour of connections between cold-formed steel members and fibre cement sheathing based on experimental monotonic and cyclic tests. Test results show sensitivity of the strength, and mode of failure, to the edge distance of the fasteners amongst other design parameters. Cyclic test results show a highly pinched hysteresis response associated with significant stiffness and strength degradations at higher displacement amplitude, which is typical in such bracing walls. The load-deflection curves for the connections enable full scale finite element models to be developed for predicting the performance of such bracing walls under seismic actions.
