Overview

This analysis shows how slab contributions influence progressive collapse in multi-story buildings, suggesting seismic design improves resilience.

Key Points

  • Models without slabs experienced collapse in all scenarios, highlighting the importance of slab contributions.
  • As building height increases, displacements due to column removal generally decrease, indicating structural resilience.
  • Buildings designed for seismic resistance showed no significant plastic rotations when slab effects were included in the model.
  • The location of initial failure shifted to the adjacent column face by extending the length of the top reinforcement.
