NONLINEAR-ANALYSIS OF I-BEAM TO BOX-COLUMN CONNECTIONS

The behaviour of 1-beam to box-column connections stiffened externally has been studied earlier both experimentally and theoretically and th e stress analysis from the results is presented in this paper. Differe nt types of external stiffeners have been investigated and extensive s train measurements were made on the experimental models. Stresses have been computed from the measured strains. Detailed analysis of the dis tribution of longitudinal and transverse stresses and principal stress es at selected locations of typical specimens are presented in the pap er. The results presented show stress distribution and the spread of y ielded zones at various stages of loading. Comparisons have also been made between the values of stresses obtained experimentally and analyt ically.
