Overview

Parametric analysis evaluates punching shear in slabs with asymmetric openings, suggesting design code improvements.

Key Points

  • The results indicate that design codes may underestimate punching shear capacity in slabs with asymmetric openings.
  • The analysis focused on variables like opening configurations and reinforcement, revealing their significant impact on performance.
  • A behavioral hypothesis suggests that as the asymmetry increases, it behaves similarly to eccentricity, with noteworthy limitations.
  • The findings provide a preliminary framework for future studies on the design and evaluation of flat slabs.
