ABSTRACT
Similarities between diagonally tested infilled frames and those subjected to racking load were investigated. With the sole parameter being the beam-to-column relative stiffness Ib/ Ic , two series comprising fifteen one-third scale models of square infilled frames were fabricated and subjected to in-plane lateral loading. Eleven units were tested diagonally and racking loads were applied on four specimens. Despite different types of loading, specimens exhibited similar behaviour in terms of load vs displacement of the compressed diagonal. strength, stiffness and failure modes. Test results suggest that diagonally tested infilled frames provide a reliable alternative to racking tests.
