Rigid Joints Transferring Forces outside Box Columns with Deviation of Column's Verticality - Finite Element Method Simulation

Abstract

Three groups of specimens were designed in this paper to compare the performance of rigid joints transferring forces outside box columns to that of traditional joints by finite element method program ANSYS. The influences of deviation of verticality in columns on stiffness, yielding capacity, and ultimate carrying capacity were analyzed. The evaluation of working performance by adding force-transforming plates could be found. The thickness and width of adding plates would be the key parameters of steel frame joints. This paper put forward the optimal range of design parameters.
