ABSTRACT
Tests have been carried out on eight full-scale composite connection specimens. The specimens were made by connecting either one or two steel beams to concrete-filled rectangular hollow section (RHS) tubular columns. The beams in the latter case were unsymmetrically loaded. The columns were hence subjected to axial loading and bending moments, and thus represented actual columns in multi-storey buildings. The loads on column and beams were increased proportionately up to failure, and the tests were continued into the post failure stage. Some of the test results have already been published, and the load-response of the columns are compared here against the numerical results of a 3-dimensional finite element programme.
