Abstract:

Changing columns' positions or directions through different floor levels may cause many problems if not taken into design considerations. Unfortunately, there are no specifications or design requirements in the different codes of practice to design beams that have planted columns. This theoretical investigation aims to specify the planted column-beam connection's behavior, considering the beam width, the direction of the column, its dimensions, and shear reinforcement distributions. Therefore, a three-dimensional nonlinear finite element analysis was carried out for 17 models sorted into 5 groups. It was observed that the longer side of the planted column direction, which is perpendicular to the beam span, had better behavior in failure load and deflection than it was parallel to the beam span. Also, the planted column length preferred to be taken the same as the beam width for better behavior.

Keywords:
