Effect of using highly confined short lap-splice reinforcement on seismic performance of exterior beam-column joint

Abstract EN

The present paper aims to examine the behavior of exterior beam-column joints with different reinforcement details of their columns: continuous and lap splice longitudinal bars were adopted as design parameter.

The experimental program was carried out at the Concrete Research Laboratory at Housing and Building Research Center in Egypt; included three exterior reinforced beam column joints that were tested under the effect of quasi-static cyclic loading.

One sample was designed according to the provisions of the current seismic design codes and served as a control sample.

Columns of the other two samples were detailed with well confined shorter lap spliced longitudinal reinforcement.

The overall behavior of the beam-column joints and conclusions are discussed in this paper.
