<br />DELAWARE COASTAL VULNERABn.rry AND CONSTRUCTION STANDARDS STUDY
<br />Anthony p, Prall, Christopher P. Jones, P,E" Spencer M, Rogers, and Darryl 1. Hatheway
<br />
<br />Nationwide, coastal development and population trends have collided with erosion of our shorelines and damage from severe storms, and
<br />have focused attention on the need for improved building siting and coastal construction standards, The consequences of poor siting
<br />decisions and inadequate construction standards are demonstrated daily at some point along our nation's shorelines, In Delaware, previous
<br />storms have repeatedly shown the vulnerabilily of certain types of construction, particularly older, at-grade or inadequately elevated buildings
<br />close to the shoreline, FEMA's Building Performance Assessment Report following the January 1992 northeaster highlights typical damages
<br />experienced by shorefront construction in Delaware (FEMA 1992), R=t coastal siting and construction standards, though improved, stilJ
<br />leave some coastal development vulnerable to damage or destruction during severe storms, The potential consequences of not further
<br />improving coastal siting and construction standards are great-loss of residential and commercial property, business intenuption and job
<br />loss, and, of course, the threat to human life itself The Coastal Vulnerability and Construction Sbmdards Study has been penonned to
<br />address these concerns. Specifically, the study has been conducted to: (I) better define the nature and extent of coastal hazards along
<br />Delaware's Atlantic Ocean and Delaware Bay shorelines, (2) map coastal hazard zones reflecting present day shoreline conditions, (3) map
<br />future (30-year) hazard zone locations along the Atlantic Ocean and Delaware Bay shorelines which account for 10ng-tenn erosion 'and
<br />shoreline recession and assumes that no further beach nourishment takes place, and (4) supplement existing building codes and regulations
<br />with standards specifically tailored to the identified hazard zones,
<br />
<br />The present study has three key phases: Phase I, Coastal VuInerabilily Assessment and Mapping; Phase 2, Development of Coastal
<br />Construction Standards; and Phase 3, Coastal Vulnerability and Buildin~ Standards Workshop,

<br />SEI/ASCE STANDARD ON FLOOD RESISTANT DESIGN AND CONSTRUCTION
<br />James A, Rossberg, P,E.
<br />
<br />In 1998 the Structural Engineering Institute (SEI) of the American Sociely of Civil Engineers (ASeE) will publish a national consensus
<br />standard on Flood Resistant Design and Construction. This standard was developed in accordance will] ASCE's procedures as an American
<br />National Standards Institute (ANSI) accreditated standards developing organization and will be submitted for adoption by reference into
<br />the International Building Code (!BC) being developed by the International Code Council (ICC),
<br />
<br />This new Standard provides minimum requirements for flood-resistant design and construction of structures located in flood hazard areas.
<br />This slllndard applies to new construction which includes new structures and work classified as substantial repair or substantial improvement
<br />of an existing structure that is not an historic structure,
<br />
<br />The presentation will include: a brief review of ASCE's consensus standards development process; a brief discussion of the !BC and the ICC;
<br />and a review of the contents of the standard. A complete table of contents for the document is available to the reviewers oflhis abstract upon
<br />request

<br />THEORETICAL ANALYSIS AND W AVE TANK TESTING OF BREAKA WAY WAl,L PANELS FOR USE UNDER
<br />PILING-SUPPORTED COASTAL BUILDINGS
<br />S, M. Rogers, Jr" S,C, Yeh, C, K. Sollill, B. Kasal, C, C, Tung & Cliff Oliver
<br />
<br />The paper will report on two years of FEMA and NSF sponsored research on breakaway walls for use under piling-supported buildings
<br />conducted by Nor1h Carolina State University and Oregon State University, The research included extensive testing of nailed connections,
<br />an analysis of the theoretical forces on a wall caused by various types of waves and the destructive testing of full-scale wall panels in the
<br />wave tank. The research is eventually expected to influence FEMA construction regulations and the new edition of the Coastal Construction
<br />Manual,
