CYCLIC BEHAVIOR OF BEAM-TO-COLUMN STEEL JOINTS WITH SLENDER WEB PANELS

Thirteen experiments are performed to investigate the cyclic behavior of beam-to-column joints of steel frames with slender joint panels. Th e performance of the joints with respect to strength, rigidity, ductil ity, and low cycle fatigue are examined. Three different load-carrying mechanisms can be identified. They are the shear action of the web pa nel, the tension field action, and the frame action of the surrounding elements. The various characteristics of these actions as determined by the experiments are discussed. It is concluded that a good performa nce can be achieved by properly selecting the dimensions of the web pa nel, the surrounding flanges, and their relative proportions.
