Experiments on Eccentrically Braced Frames with Composite Floors

摘要

The results of an experimental study on the cyclic behavior of short links in eccentrically braced steel frames (EBFs) with composite floors are presented. The study includes eight tests which were performed on two-thirds scale subassemblies consisting of floor beams of EBFs. Two of these specimens were bare steel, with the remaining six consisting of steel sections with a composite floor slab. The results of each test are analyzed to determine the increase in cyclic link capacity due to composite action, whether cyclic web buckling in composite links can be inhibited using bare steel link design criteria, and the extent of participation and damage of the concrete floor slab under extreme loading.
