Abstract
The paper presents an investigation on the structural performance of shear resisting connections between cold-formed steel sections where web cleats of cold-formed steel strips are used to attach beams to supporting beams and columns. A total of 24 connection tests with four different connection configurations were carried out; three modes of failure were identified: failure of fasteners shear buckling of cold-formed steel web cleats or webs of supported beams, and lateral torsional buckling of cold-formed steel web cleats The structural performance of the cold-formed steel web cleats in four different connection configurations is presented in detail. It is demonstrated that cold-formed steel web cleats may be used with bolts or self-drilling self-tapping screws as practical shear resisting connections in building construction. A set of design rules is formulated in accordance with both BS5950: Part 5 and Eurocode 3: Part 1.3 after calibration against test data. The rationalized usage of cold-formed steel web cleats allows simple and effective connections to be formed between cold-formed steel sections leading to improved buildability.
