Paper Title:
Analytical Evaluation of Plastic Resistance of Column Base Connection Using Convex Set Theory
  Abstract

It is important to estimate the structural safety of column base connection by calculating exact collapse loads. Column bases connection transfer reactions from the structure the foundation. In this paper, a simple mechanical model to predict their plastic resistance is proposed. An efficient linear-programming technique, which is called as Compact Procedure, is applied to column base connection model including multi-spring elements, where a column base is replaced by a set of plastic axial and bending springs. In Compact Procedure, it is not necessary to know the whole interaction surface of resistances at a plastic portion. A simple analytical model of column base connection to calculate its load-carrying capacity considering bi-axial loading effect is presented. In addition, efficiency of the proposed model is examined by comparing it with the past test results.
