Overview

Experimental assessment demonstrates defects reduce load-bearing capacity and ductility in precast shear walls, highlighting effective reinforcement strategies.

Key Points

  • Defective precast shear walls exhibited significant reductions in load-bearing capacity and ductility, affecting safety.
  • Results showed that energy dissipation was enhanced by reinforcement strategies in previously defective walls.
  • Quasi-static testing on full-scale shear wall specimens revealed the impact of grouted sleeve connection defects.
  • Understanding failure mechanisms highlights the importance of structural integrity in precast shear walls.
