INTRODUCTION connection type considered here

angle with double web-angle connections as shown in Fig. 1. This connection type has the inherent ural deformation of both flange and angles in the legs attached to the column. In this paper, an developed to predict the moment-rotation ultimate capacity. three-parameter power model is used here to represent the whole moment-rotation behavior of the con- nections. experimental results reported et al (1982) and Azizinamini et al (1985) are used here to verify the proposed procedure.
