Abstract (EN): This paper deals with the experimental behaviour of blind-bolted angle connections between open beams and tubular columns. A number of connection configurations with different geometric arrangements and bolt properties are examined. The experimental set-up, connection details and material properties are first described. A detailed account of the results and observations from seventeen monotonic and cyclic connection tests is then presented, and the main behavioural aspects are discussed. The specimens include connections with top and seat angles as well as others in which web angles are also incorporated. The experimental results offer direct information on the influence of important geometric and material properties, such as angle dimensions, column face thickness, gauge length and bolt class, on the key response characteristics including stiffness, strength, energy dissipation and failure mechanism. Based on the findings, simplified approaches through which the initial stiffness and yield parameters can be estimated, are assessed. The test results also provide essential data for the future validation of detailed numerical and analytical studies which can be employed for further assessment of the response, with a view to the development of design-oriented procedures.
