Effect of different transverse bars arrangements on the behavior of concrete columns under impact loading

Due to the fact that common structures are designed only against gravity and seismic loads, the performance of these structures must be investigated against impact loading, in order to protect against this damage if necessary. In this paper, the effect of the arrangement of different shape of transv...

In this paper, the effect of the arrangement of different shape of transverse bars and their spacing on the performance of beam-column element against blast loading has been studied. In this study, 13 model of concrete beam-column element with different transverse bar arrangement has been explored to examine their performance against explosions with 25 kg TNT.
