EXPERIMENTAL STUDY ON IMPROVEMENT OF PLASTIC DEFORMATION CAPACITY OF STEEL BEAM BY STIFFENER MADE WITH 3D PRINTER

Abstract

In this paper, the effect of stiffener made with 3D printer to plastic deformation capacity of steel beam is confirmed by loading test. Firstly, plastic deformation capacity and collapse mode of H-shaped steel beam without stiffener is confirmed by FE analysis. Secondly, for improvement of plastic deformation capacity, stiffener made with 3D printer is designed. And then, loading test of H-shaped steel b eam with this stiffener is conducted and effect of t his stiffener is examined by comparing the result of non-stiffened beam.
