STUDY OF THE SHEAR DEFORMABILITY OF COLUMN WEB PANELS IN STRONG AXIS BEAM-TO-COLUMN JOINTS. IN: STRUCTURAL STABILITY RESEARCH COUNCIL. 1990 ANNUAL TECHNICAL SESSION, STABILITY OF BRIDGES, ST. LOUIS, MISSOURI, APRIL 10-11, 1990

Numerous numerical simulations of "T" and "cross" beam-to-column joints have been performed. The parameters investigated in this study were the type of beam(s) and of column, the loading of the joints, the transversal initial deformation of the column web and the presence or not of stiffeners on the column web. This analysis has allowed: (1) to define accurately the shear force of the joint under any solicitation; (2) to show clearly the influence of the above mentioned parameters; (3) to enlarge the knowledge on the physical behavior of the joint up to failure. Theoretical developments have led to a new approach for the mathematical prediction of the nonlinear behavior of unstiffened column web panels. The model proposed has been validated for the column webs of joints with end-plate connections. Lastly, the EC3 formula for the assessment of the shear plastic capacity of the panels is discussed.
