Abstract:
Dynamic tests of two sets of parallel one-bay, two-story concrete plane frames were carried out at the University of British Columbia to assess the effectiveness of using steel fiber reinforced concrete in the design of seismic-resistant structures. The second set was modified by removing a substantial number of confining hoops from the joint region and adding steel fibers to the concrete mix. The modified SFRC frames maintained better joint integrity than the conventionally detailed frames, with minimal concrete spalling during even the high-magnitude earthquakes. Analysis of the test data also showed the SFRC frames to have absorbed more energy hysteretically. The tests clearly demonstrate the potential of steel fiber concrete in the seismic design of concrete structures.
