Composite joints subject to reversal of loading-Part 2: Analytical assessments

Abstract

The experimental results of composite beam-to-column joints subject to reversal of moments have been reported in the companion paper [J. Construct. Steel Res. 2003 Doi: 10.1016/j.jcsr.2003.08.010]. This paper presents the analytical assessment of moment capacity and initial rotational stiffness of the beam-to-column joints. The predicted results are compared with those obtained from the tests. The component method extracts from Eurocodes 3 and 4 and its companion document was used to determine the negative moment capacity and initial rotational stiffness. Based on the same principles, the method was extended to calculate the properties of joints subjected to positive moment. Comparison of results shows reasonable correlation except, however, the Eurocode method is found to overestimate the rotational stiffness of joint specimens subjected to negative moment. © 2003 Elsevier Ltd.
