ACI PRC-377-21: Integrity and Collapse Resistance of Structural Concrete Floor Systems - Report

Description

This report provides a summary of the present understanding of collapse-resisting mechanisms of reinforced concrete and post-tensioned flat plates, flat slabs, slabs with beams, joist floor systems, and precast floor systems following initial local failures.

Keywords:

beam growth; catenary action; collapse resistance; collapse-resisting mechanisms; column removal; compressive membrane action; emulative connection; flat plate; flat slab; floor systems; joist floor; post-punching capacity; post-tensioned; precast; punching; structural integrity.
