Title: Importance of Reinforcement Detailing
Author(s): Denis Mitchell, William D. Cook, and Ting Peng
Publication: Special Publication
Appears on pages(s): 1-16
Abstract:This paper describes the collapse of the Concorde Overpass that was partly due to improper hanger reinforcement details in the disturbed region (D-region) of the beam seat. A review of the evolution of the hanger reinforcement details in dapped end beams given in different versions of the PCI Design Handbook is presented. The results of a series of experiments on dapped end beams with different hanger reinforcement details are described. Guidance from these tests and other experiments on the details of anchorage of the hanger reinforcement in dapped end beams is provided.
