  • Abstract:
  • Earthquakes are very dangerous to buildings, especially ones whose structure is irregular or the buildings are constructed on slanting land. Edifice structures on sloping grounds suffer unequal distribution of stiffness and complicated load transmission, whereas irregular plans like L-shaped and T-shaped constructions are likely to be affected by torsion and consequently seismically vulnerable. The work is an investigation of the composite effect of the plan irregularity and ground slope on seismic performance considering 54 structural models created in ETABS V22, which includes Rectangular, L-shaped, and T-shaped plans on slopes between 5o and 20o. Consistent modeling was done using a six-spoke grid or the 60 degrees internal angle, and Response Spectrum Analysis according to the seismic design requirements tested such parameters as base shear, roof displacement, fundamental time period and lateral stiffness. The results indicate that the plan irregularity and slope inclination have a significant effect on the behavior of the structure- Rectangular models were found to be the best on the mild slopes, L-shape and T-shape models had higher displacements, lower stiffness, and natural periods on steep slopes. These findings strongly indicate that the consideration of geometrical and topographical factors in the design of seismic buildings is needed to improve the resistance of buildings in earthquake-prone areas.
