Life-Cycle Performance of Civil Structure and Infrastructure Systems: Survey

The survey presented in this paper has been conducted on behalf of the SEI/ASCE Technical Council on Life-Cycle Performance, Safety, Reliability and Risk of Structural Systems, Task Group 1 on Life-Cycle Performance of Structural Systems under Uncertainty, as part of a SEI-funded Special Project approved by the SEI Technical Activities Division Executive Committee. The funding institution is gratefully acknowledged, with special thanks to Robert Nickerson, SEI Board of Governors and SEI TAD Executive Committee Contact of the Technical Council. The results of the survey have been presented at the International Workshop on Civil Structure and Infrastructure Systems organized and chaired by the authors of this paper and held at the ASCE Headquarters in Reston on November 10, 2015.

The authors wish to gratefully acknowledge the dedicated work and contributions of Andrea Titi of Politecnico di Milano to both the development of the survey and organization of the workshop. Special thanks are owed to Susan Reid of SEI/ASCE for the important and professional support in the organization of the workshop. The information available from previous surveys conducted by ASCE is also gratefully acknowledged, particularly the ASCE survey on Utilization of Life-Cycle Cost Analysis and Performance Based Design, organized by Dan M. Frangopol, Mohamed Soliman, and Samantha Sabatino, Lehigh University, and the SEI/ASCE TC TG2 TG3 survey on Implementation of Risk-Based Methods for the Design of Structure and Infrastructure Systems, organized by Michel Ghosn, City College of New York; Ming Liu, U.S. Department of the Navy; and Bruce R. Ellingwood, Colorado State University.
