It is not desirable that yielding due to shear force occurs in the beam-to-column connections below the flexural yield load in pipe columns. A calculation shows that "shear yielding" will often occur prior to yielding by flexure. Such yielding may cause large deformations of the frame. This paper is conserned with the study into the reinforcement of connections fabricated of steel pipe columns and H-shape beams. The specimens, having various reinforcements and different dimension in steel pipes and stiffening plates, were tested. The most efficient reinforcement was found to be the doublar stiffening plates, Fig.4(c). The stress and deformation of the so reinforced connections can be predicted by the ordinary beam theory. An equation was obtained to determine the desirable thickness of stiflening plates, Eq.(10).
