ABSTRACT

Cold-formed steel anchor plate is widely used in the local construction industry especially in lightweight roof truss system. It is used to connect a truss to its support, transferring load. Sometimes these anchor plates are used to level a truss without a wall plate. The truss then, depended on the anchor plates to carry them in place until grouting is done. The clearance between the support and a truss can go up to a 100mm high. As with other thin-walled structures, stability is a critical design issue here. This paper examines the effect of plate thickness and load profiles on the plate performance. A total of 18 tests were conducted to determine the ultimate capacity of the anchor plate. The load measured from the experiment was used to determine the eccentricity of the system through Parametric Column Analysis. Results indicate that the thicker and longer the plate, the higher the imperfections. By taking the worst case condition, a factor of 0.17 is used to calculate the capacity of the anchor plate.
