Development and Design of Untopped Precast Concrete Diaphragm Systems for High Seismic Zones (Extension)

Research purpose

The objectives of the work supported by the CPF grant were:

  • to develop and demonstrate untopped and topped precast diaphragm systems that will provide good performance in regions of high seismic hazard
  • to produce a design and detailing procedure for these systems for high seismic zones
  • to codify this design procedure and create design aids

Note: The Charles Pankow Foundation research grant supported concluding phases of work resulting from a larger, integrated project supported in previous years by the National Science Foundation and the Precast/Prestressed Concrete Institute.
