1 Annual Meeting Luncheon MCEER s s Post-Hurricane Katrina Reconnaissance Investigations Featured Speakers Gilberto Mosqueda, University at Buffalo Lucy Arendt, University of Wisconsin-Green Bay Ryan Shannon, Tulane University

2 Hurricane Katrina Made landfall on August 29, 2005 at 7:10 AM near Louisiana-Mississippi border Category 3 hurricane with sustained winds of 125 MPH, storm surges up to 28 ft., and strong winds up to 100 miles away from it center Most destructive and costly disaster in US history Multihazard event: wind, storm surge, and flooding Background photo credit: NOAA

3 Hurricane Katrina Saffir-Simpson Hurricane Intensity Scale (ASCE 2005) Category Wind speed (mph) >155 Barometric Pressure (in) <27.17 Storm surge (ft) >18 Level of damage minimal moderate extensive extreme catastrophic Background photo credit: NOAA

7 MCEER Reconnaissance Objectives Assess damage to built environment and emergency response and recovery from a multi-hazard perspective Examine lessons learned and their application to disaster mitigation for other extreme events (earthquakes, terrorist attack) Extent of damage required multidisciplinary investigations; teams with various expertise were deployed

8 Multidisciplinary Investigations Remote Sensing Shubharoop Ghosh, ImageCat, Inc. Carol Hill, Louisiana State University Arn Womble, Texas Tech University Damage to Buildings, Bridges, and Lifelines Paul McAnany, Practicing Engineer Gilberto Mosqueda, University at Buffalo Jerome S. O Connor, MCEER Keith A.

9 Areas of Investigation 100 miles Katrina s Path

10 MCEER Reconnaissance of Mississippi and Alabama Teams deployed Sept to Mississippi and Alabama Remote sensing Structural investigations Teams deployed Oct. 3-9, Oct to New Orleans Remote sensing Structural damage investigations Response of hospitals, transportation systems and other critical facilities Environmental and public health issues

11 Rapid Dissemination - Web Reports Posted from Field

12 Technical reports available

13 Remote Sensing Use remote sensing technologies and the VIEWS TM reconnaissance system in post Katrina urban damage assessment Wind, storm surge, flooding and levee breach Use in-field observations to correlate and validate nature and extent of damage detected from Satellite images

21 Structural Damage Investigations Examine damage to large engineered structures, primarily bridges and commercial buildings Assess structural damage from a multihazard perspective; similarities to other hazards Identify potential applications of seismic design principles to mitigate hurricane damage

22 US 90 Eastbound Pass Christian to Bay St. Louis, Mississippi

23 Bridges Biloxi Bay CSX Railroad Pedestrian Bridge US-90 N

24 Bridges

25 Railroad bridge over Biloxi Bay

26 U.S. Gulf Coast Major Bridge Damage

27 Collapse of Parking Structures Due to Storm Surge

28 Some parking structures performed well

29 Partial collapse of parking structures in Biloxi Partial collapse storm surge Partial collapse impact No structural damage Internet Map Server Art Lembo, Cornell

30 Buildings in Downtown Gulfport Few collapsed unreinforced masonry structures Most engineered buildings suffered only nonstructural damage Rain and wind penetrated building interior through broken windows

31 Gulfport Coastal Hotels Significant nonstructural damage to building exterior and interior

32 Partial Collapse of Building Due to Barge Impact Impact

33 Glazing damage to downtown New Orleans office buildings

34 Preliminary Lessons Learned: Structural Damage Structural damage caused by storm surge and surge-borne debris (casino barges) Storm surge damaged mainly precast concrete structures: bridges and parking structures Significant nonstructural glazing damage occurred to structures that were downwind of gravel roofs due to wind and wind-borne debris Additional damage in building interior Backup systems located in basement were damaged by flooding

35 Multihazard aspects: Structural damage Similar losses occur in earthquakes & hurricanes importance of nonstructural elements Precast bridges and parking structures had similar failure in past earthquakes Photo Credit: Los Angeles Times Seismic resistant details have been developed for precast construction and may be useful for storm surge resistant design

36 Multihazard aspects: Overall Combined disasters Hurricane Katrina followed by flooding destroyed New Orleans In 1906 San Francisco Earthquake ground shaking followed by fires destroyed San Francisco Need to consider multiple hazards in enhancing resilience of communities

37 Hospitals in New Orleans

38 Why study hospitals? People expect hospitals to withstand all natural disasters, including floods, hurricanes, blizzards, and earthquakes. People expect hospitals to respond when their community faces nuclear, industrial, transportation, or other manmade disasters (e.g., terrorism). Hospitals merit special attention thanks to their complexity and occupancy characteristics, and because of their role during disasters.

40 Disaster Preparedness & Response Hospitals prepared and performed well during the Hurricane, but were shocked by the widespread flooding that followed.

46 The Aftermath Hospitals evacuated after their ability to deliver quality healthcare became compromised.

58 Preliminary Lessons Learned: Hospitals Constructing Resilient Building Systems: Hospitals should have their own power and water supplies independent of municipal utilities. Expecting To Be Self-Sufficient: Hospitals should expect to be on their own in the event of an emergency. Networking: Hospital staff members should build strong networks with local, regional, state, and national sources of assistance (both governmental and private).

59 Preliminary Lessons Learned: Hospitals Staffing: Hospitals should continue to hire the best staff members and be certain that those staff members are on site when needed. Communicating Emergency Plans: Hospitals should plan for the worst and be certain that all staff members know their role in an emergency. Leading Effectively: Having planned for the worst, hospital executives should be poised to lead.
