Overview

This comprehensive review analyzes how punching shear and shear reinforcement impact flat slabs, indicating design code limitations.

Key Points

  • Punching shear critically threatens reinforced concrete flat slabs, leading to dangerous progressive collapses.
  • The review highlights design code limitations, especially for slabs with low reinforcement ratios and complex geometries.
  • Nonlinear finite element analysis reveals essential insights into shear reinforcement and structural performance.
  • Lessons from real-world building failures outline the need for robust design and integration of construction-phase analysis.
