Abstract

Direct analysis method (DAM) is the new generation design method, which has been widely documented in world-wide design codes, such as Chinese Steel Code GB50017-2017, Hong Kong Steel Code CoPSC 2011, Eurocode 3, American Steel Code AISC 2016, etc. The core philosophy of this method is to consider all the dominant factors affecting the structural behaviors in terms of material yielding and buckling. A robust numerical method, using the sophisticated beam-column elements of being capable to simulate member's real deformations associated with the internal forces, is the key in successfully executing the DAM in practices. In this paper, an advanced beam-column element, called as the arbitrarily-located hinge (ALH) element, is reviewed where its fundamental element formulations are derived with details. Unlike the conventional plastic hinge element uses several elements to simulate one member for reflecting the inelastic deformation along member length, causing difficulties in modelling initial imperfection, one ALH element per member is sufficient for the analysis. At last, several featured examples are given for the verification and validation of the method.
