• Abstract:
  This report discusses the main findings of a test examining the seismic behavior of a precast, post-tensioned, segmental bridge
  
  superstructure with a cast-in-place, hollow, rectangular column. The half-scale specimen modeled a prototype bridge from midspan to
  
  midspan and down to midheight of the column. The bridge was built using the balanced cantilever method and the tendon layout of
  
  the specimen was designed to most closely match that of the prototype segment joints nearest to the column.
  
  The test was completed in two stages; the first stage prestressing level was designed to avoid any joint openings. This was a
  
  validation of existing bridge design procedures in which damage is limited to the column, and the superstructure remains elastic. The
  
  second stage involved removing some of the tendons to enable inelastic deformations of the joints in the superstructure and to impose
  
  on the joints nearest the column a more severe loading condition. The second stage of the test was done as an introductory
  
  examination of the performance of a bridge when damage is not limited to the column and inelastic motion is allowed in the
  
  superstructure.
  
  The primary objectives of the test were to investigate the response of the opening of the superstructure joints, column-superstructure
  
  interaction, plastic hinge formation in the column, and the anticipated system failure mechanism. Extensive instrumentation was used
  
  in the column as well as the joints of the superstructure to record the damage and performance of those bridge components
