Numerical and experimental study of behaviour of column-based connections under bending

摘要

Numerical modelling and experimental analysis of base plated column-base connections is the subject of this paper.The actual semi-rigidity of these connections could have a significant influence on the structure's response.A nominally pinned and a fixed column-base connection was studied by numerical simulations,in the fraework of a parametric study,completed and verified with experimental tests.To model the moment-(relative) rotation characteristic of the connections,the Richard function is integrated in the finite element model of a beam element.
