Dr. Ayyub’s main research interests and work are in risk, resilience, sustainability, uncertainty and decision analysis, applied to civil, infrastructure, energy including renewables, defense and maritime fields and climate-resilient infrastructure. Professor Ayyub is a distinguished member of ASCE and an honorary member of ASME. He is also a fellow of the Society of Naval Architects and Marine Engineers (SNAME), the Structural Engineering Institute (SEI), and the Society for Risk Analysis (2017-18 Treasurer), and a senior member of the Institute of Electrical and Electronics Engineers (IEEE). Dr. Ayyub completed research and development projects for governmental and private entities including NSF, DOD, DOT, NIST, DHS, and leading insurance and multinational corporations worldwide. Dr. Ayyub is the recipient of several awards, most recently the 2018 ASCE Alfredo Ang Award on risk analysis and management of civil infrastructure, 2019 ASCE President Medal for many efforts to bring adaptive design to the profession to help address a changing climate, 2019 ASCE Le Val Lund Award for contributions to resilience enhancement and risk reduction for lifeline-networked systems through measurement science and associated economics toward informing policy and decision-making practices, 2018 ENR Newsmaker award for passionate effort to give engineers their first formal guidance when designing infrastructure to be more resilient to weather extremes, and 2016 ASNE Solberg Award significant engineering research and development accomplishments in the field of ship survivability. 

Reliability-Based Design of Ship Structure

Principal Investigator(s) 

Ayyub, Bilal M.

The development of reliability-based design criteria for surface ship structures needs to consider the following three components: (1) loads, (2) structural strength, and (3) methods of reliability analysis.  A methodology for reliability-based design of ship structures was developed and implemented.  The methodology consists of the following two approaches: (1) direct reliability-based design, and (2) load and resistance factor design (LRFD) rules.  Reliability-based design rules were developed at several levels of structural systems that include the hull-girder, grillage, panel, plate and detail levels. This multi-year effort contributed towards the development of the American Bureau of Shipping Rules for the U. S. Navy.  Fatigue design in these rules are based on products from this research effort that first appeared in the special issue of the American Society of Naval Engineers Naval Engineers Journal.
