Basic Structure System Rating of Post–Super Typhoon Haiyan Structures in Tacloban and East Guiuan, Philippines
Publication: Journal of Performance of Constructed Facilities
Volume 30, Issue 5
Abstract
This paper reports the investigation outcomes of the recent Super Typhoon Haiyan (also known as Hurricane Yolanda) in the Philippines using a basic structure damage rating technique. The rating technique ranked damaged conditions based on a 0 to 3 rating. A total of 156 structures were analyzed using the rating technique. Unlike previously published condition ratings, the technique does not include functional assessments such as mechanical and electrical systems and does not directly consider habitant safety nor costs to structure. The intent of the rating is to provide a quantitative measure of the effects of Haiyan. The outcomes indicate that wind damage dominated as the major cause of failures (53%) and that roof damage is the most significant of the damage modes (21%). The rating gives a first-order assessment of the damaged conditions of the structures pertaining to the loading effects (wind, water or storm surge, or combined) from Super Typhoon Haiyan.

Acknowledgments
The field team would like to extend its gratitude and appreciation to ASCE for sponsoring the study and to committee on technical advancements (CTA) for approving the project, in particular CTA members Mr. Bob Bachman and Ron Smith for their guidance. Also, the field team would also like to extend special acknowledgement to ASCE staff members Mr. Jim Rossburg, Mr. John Segna, Ms. Meggan Maughan-Brown, and Mr. Tenzing Barshee for their tireless support and facilitation of the project. The field team also greatly appreciated the efforts of Mr. Doug Scott for daily blog updates of the field team study. The authors would like to acknowledge National Science Foundation (NSF) Program Director Dr. Kishor Mehta for supporting this project under awards 1426445 and 1433262. The authors are grateful to the local support from PICE and ASCE Region 10. The field team is thankful for meeting Under Secretary Honorable Danilo Antonio and for receiving support from PICE President Ernesto S. De Castro and former ASCE Region 10 Director, Potenciano A. Leoncio, Jr. Gratitude is especially due to the logistic arrangements made by PICE national administrative officer Nannette C. Villanueva and Mr. Ferdie Briones. This project is a team effort from ASCE members, ASCE international partners, and people from the area of Leyte. Without ASCE’s international partners, it would have been impossible to conduct such studies. Meeting with several local mayors, including Mayor of Tanauan Mr. Pelagio O. Tecson III, Mayor of Palo Ms. Remedios L. Petilla, Mayor of Dulag Mr. Manuel S. Que, Mayor of Tolosa Erwin C. Ocaña, Region VIII Department of Public Works and Highways Director Mr. Rolando M. Asis, and Port Manager of Port Management Office of Tacloban City Mr. Dominador D. Licayan, allowed the field team to hear firsthand the unfortunate events and the suffering of their constituents. These mayors are courageous and dedicated in bringing in external resources to help bring lives back to normal. The authors also like to acknowledge the University of North Carolina Charlotte Mosaic team for putting together the website in record time including Jack Stein, David Whistler, Jason Edgecombe, Sai Phaninder Jonnala, Bryron Ho, Andre Sanchez, Vivek Pawar, and Nathaniel Hatley. Shen-En Chen would like to acknowledge the Fulbright-Nehru Scholarship that allowed him time to analyze the data in Tirchuchirappalli, India. Last but not least, the authors acknowledge local team members, especially the two translators Valerie Ambait and Nile April Robino. Both are law school students who spent days with the team amidst their busy exam schedules.
