Thus the present study was initiated to investigate the seismic performance of interior beam-column joints under axial beam tension. This paper, by means of inelastic dynamic time history analysis, presents a comparison of seismic responses of ordinary RC frame structures and step back RC frame structures on hill slopes, showing the damage of interior beam-column joints under axial beam tension subjected to earthquake excitations. Also finite element simulation of beam-column subassemblages is investigated in this paper. By comparing the behaviors of ordinary beam-column subassemblages and beam-column subassemblages under axial beam tension subjected to lateral loads, the impact of axial beam tension on joint shear capacity is analyzed. Research results indicated the existence of significant axial beam tension in step back frame structures on hill slopes and loss of shear capacity when tension is experienced. Hence a realistic estimate of joint shear capacity is deemed crucial. Finally, suggestions for improvement in calculating joint shear strength demand are provided.
