Representation of Screw Connections for Sheathing Boards in Light Weight Structures

Document Type : Review Article

Abstract

In this study, experimental and numerical investigations are conducted to characterise the screw behaviour in the connection between cold formed section and different sheathing boards alternatives. The investigated sheathing board alternatives include Steel sheets, Fibre-cement boards and Gypsum boards, which are typically used as cladding for the cold formed elements in light weight structures. Different types of screws are considered such as Hex Washer Head, Pan Head and Flat Head. A comparison regarding the modes of failure and shear capacity is stated. Additionally, the same connections are a represented numerically using finite element model, which is verified against the experimental test results. The connection representation showed close behaviour and failure modes compared to the experimental results. In this study, the numerical model approach is elaborated, which will be used as a component of another research program including testing full scale light steel panel subjected to cyclic loading
