Abstract

In this paper, various design codes for lateral bracings are compared about beam strength, plastic deformation capacity, out-of-plane deformation and stiffening force. Maximum beam strength showed full plastic moment and the strength was maintained until beam end rotation angle 0.045 rad. Plastic deformation capacity R showed three or more. Out-of-plane deformation was almost within 150mm. However, stiffening force was large in long beam. In design code, required stiffening force is 2 to 3% of compression force of flange, but maximum stiffening force was 9%.
