PEER Research in ACI Structural Journal: Post-earthquake Axial Capacity of Circular Bridge Columns

Evaluation of Post-Earthquake Axial Load Capacity of Circular Bridge Columns”, written by Vesna Terzic and Bozidar Stojadinovic, was published in ACI Structural Journal Vol. 112 No. 1, (p. 23-34), January – February 2015.

Sponsored by PEER and CalTrans, this project examined post-earthquake traffic capacity of typical highway overpass bridges. As a part of this research project the first experimentally and analytically validated methodology for assessing post-earthquake axial-load capacity of highway bridges(1,2) was developed, and the first quantitative guidelines for rapid post-earthquake inspection of highway bridges(3,4) were written.  Additionally, the hybrid simulation experimental technique was extended(5) to allow for multi-phase testing that was successfully used by other researchers.
