| ABSTRACT |
| The
behavior and load-deformation response of reinforced concrete exterior
beam-column joints constructed with headed reinforcement is evaluated. The
evaluation is based on the experimental results of two exterior joint
specimens, one representative of construction for high seismic regions and
one representative of construction for wind loads. An overview of the
experimental study is presented prior to evaluating the effectiveness of
the specimens constructed using headed reinforcement. Headed reinforcement
lessens congestion in beam-column joints. Use of headed reinforcement
eased specimen fabrication and concrete placement. Excellent behavior was
observed for both specimens constructed to meet current ACI-ASCE Committee
352 design recommendations. |
