Abstract: This paper examines the behaviour of semi-rigid unbraced frames through a series of tests on a variety of rectangular frames as well as their joints so that the analysis and design methodology can be developed and verified against the test results. The frame and joint tests employed similar beam and column sizes and had the same connection details. The two types of connections studied were top-seat-double-web angle and extended end-plate. Column - base connections were also included in the studies. Load-displacement plots are presented for all the test frames subjected to gravity loads applied to the beam and columns, and a horizontal load applied at the beam level. The principal objective of the joint tests is to provide a comprehensive set of moment - rotation data, in terms of stiffness and moment capacity, so that a comparative assessment of the frame performance due to the different connection types could be undertaken. Detailed descriptions of test arrangement, load sequences, test methods and data acquisition techniques are given. The general observed behaviour is discussed. Results from the frame tests are compared with the corresponding theoretical results obtained from a second-order inelastic analysis. © 1997 Elsevier Science Ltd.
