Overview

Experimental analysis reveals how opening dimensions impact seismic behavior and energy dissipation in precast walls.

Key Points

  • Group A showed reduced energy dissipation and greater pinching in hysteretic behavior, indicating poorer seismic performance.
  • Group B achieved a 12% higher peak lateral load than Group A, demonstrating better overall energy absorption and stiffness retention.
  • The study observed a three-stage failure mechanism, with Group A suffering diagonal cracking due to insufficient confinement.
  • Findings suggest that both opening size and confinement play critical roles in the seismic resilience of precast walls.
