Abstract:
This paper provides a practical example of the torsion design of an inverted tee bent cap of a three-span
bridge. A full torsional design following the guidelines of the ACI 318-19 building code is carried out and the
results are compared with the outcomes from CSA-A23.3-04, AASHTO-LRFD-17, and EN 1992-1-1:2004 codes.
Then, a summary of the detailing of the cross-section considering the reinforcement requirements is presented. The
objective of this paper is to illustrate the application of ACI 318-19 when designing a structural element subjected to
large torsional moments.
