Total Incremental Iterative Force Recovery Method and the Application in Plastic Hinge Analysis of Steel Frames

Abstract

ABSTRACT:In this paper a total incremental iterative force recovery method suitable to plastic hinge analysis is proposed and it is found that this incremental iteration force recovery procedure has a convergence rate comparable to total secant method. The incremental force recovery manner makes this method be capable of recovering member internal forces and deformations correctly and conveniently in the existence of plastic hinge. The capability of the proposed total incremental iterative force recovery method to cope with plastic hinge is illustrated by two benchmark examples.
