A STUDY ON LATERAL BUCKLING BEHAVIOR OF H-SHAPED BEAMS WITH TORSIONAL STIFFENING DEVICE : Part 2 Case of the stiffening device as the steel pipe connected to the web and flanges of H-section

Abstract

In the present study, we clarified quantitatively the effect of the torsional stiffening device as the steel pipe to the web of H-section by the results of the experiments and the theoretical analysis. And we proposed the another method to improve a lateral strength of H-shaped beam. The method is to add the steel pipes connected to the web and flanges of the H-section. This enables to increase torsional rigidity and lateral buckling strength greatly and it is possible to set up the web opening. We confirmed validity of the proposed device.
