Overview

Models compare seismic performance of beam-slab and ribbed slab systems, indicating significant implications for design.

Key Points

  • This research aims to evaluate how different slab types affect the seismic performance of reinforced concrete structures in an active seismic zone.
  • Analyzed 12 reinforced concrete building models using STA4CAD software according to Turkish Building Earthquake Code.
  • Considered three parameters: slab system (beam-slab vs. ribbed slab), plan aspect ratio (1 and 4), and soil class (ZB, ZC, ZD).
  • Evaluated models based on natural periods, base shear forces, inter-story drifts, and quantities of materials.
  • Ribbed slab systems showed lower lateral stiffness, resulting in greater displacements compared to beam-slab systems.
  • Structural demands increased with deteriorating soil class, increasing the need for shear walls and decreasing natural periods.
  • Increasing plan aspect ratio to 4 significantly raised displacement in the weak direction and the demand for shear walls.
