The University of Canterbury is at present conducting an experimental investigation into the seismic resistance of concrete building frames. This research project is sponsored by the N.Z. Prestressed Concrete Institute, the Building Research Association (N.Z.) and the University. The test frames will include a range of proportions of prestressing steel
and ordinary reinforcing steel to allow a comparison of prestressed and reinforced concrete frames and to establish the possible advantages of combining both systems. The tests are aimed at determining the deformation capacity and degree of damage of such frames when responding to severe seismic load
reversals and will establish further basic information for the evaluation and design of framed structures for earthquake resistance. Testing of the first test specimen has been completed. The specimen (Unit 1) consisted of
a beam-column assembly with a prestressed concrete beam. After testing under very severe seismic type loading the damaged concrete was repaired and the assembly retested. This
report summarizes the results obtained from
the tests on that specimen.
