Prof. Paul Anderson, Prof. Jamshid Mohammadi , and Prof. Brent Stephens of the Civil, Architectural and Environmental Engineering department will be hosting a seminar featuring Dr. Ioannis Zisis, Assistant Professor in the Department of Civil and Environmental Engineering Department at Florida International University. The topic of the seminar will be Large-Scale Experimentation Using the NSF NHERI Wall of Wind Experimental Facility to Assess and Mitigate Hurricane Wind and Rain Impacts on Buildings and Infrastructure Systems.
Wind-induced effects on buildings and infrastructure located in coastal areas of USA and around the globe have caused damages worth billions of dollars. To develop wind damage mitigation technique and carry out research on various topics of wind engineering, a state-of-the-art large scale experimental facility -- the Wall of Wind (WOW) -- was developed at Florida International University (FIU), Miami, USA. This facility includes a 12-fan boundary layer wind tunnel that can generate wind speeds of 157 mph (70 m/s) equivalent to a Category 5 hurricane on the Saffir-Simpson scale. This facility has been used for various applications that include: assessing wind loads on buildings, bridges and traffic signals; simulating wind-driven rain (WDR) intrusion in buildings; and assessing the capability of a building or its components to withstand high wind speeds. Due to its significant contributions to the wind engineering community, the WOW has been designated as an â€œExperimental Facilityâ€ (EF) under the Natural Hazards Engineering Research Infrastructure (NHERI) program of National Science Foundation (NSF), USA. This talk describes the capabilities, uniqueness, and resources at the 12 fan WOW EF. Information will be provided about the services provided by the EF staff to the Users of the facility and how to explore opportunities to utilize the NHERI WOW EF for NSF proposals on natural hazards mitigation research. User Workshop and Webinar opportunities will be highlighted. A â€˜Testing Enhancement Programâ€™ will be discussed to illustrate opportunity available to researchers with active NSF projects, who are interested in performing WOW EF testing to complement their current research projects and/or validate their numerical simulations at no cost. WOW EF case studies will be presented pertaining to the estimation of wind loads on various buildings and infrastructure systems and recently funded NSF projects will be briefly discussed. The development of innovative mitigation strategies will be described. Finally, research opportunities at the WOW EF, collaborative prospects, and fellowships/assistantships for qualified graduate students will be highlighted.
Ioannis Zisis is an Assistant Professor in the Department of Civil and Environmental Engineering Department and member of the International Hurricane Research Center (IHRC) Laboratory for Wind Engineering Research and Wall of Wind research group at Florida International University.
Dr. Zisis has been studying wind effects on the built environment for over 10 years. His research focus is structural and environmental wind engineering. He has been using advanced experimental methods, including wind tunnel and full-scale monitoring techniques, to examine how residential and other structures react to extreme wind events. The outcomes of his research efforts are aiming at the development and improvement of national and international wind standards and building codes of practice. Dr. Zisis has over 60 publications in international journals and conference proceedings and he is a member of the Structural Wind Engineering Committee (SWEC) and Environmental Wind Engineering Committee (EWEC) of the Technical Council on Wind Engineering and the American Society of Civil Engineers (TCWE-ASCE). He is also the co-PI of the NSF-supported Natural Hazards Engineering Research Infrastructure (NHERI) Wall of Wind Experimental Facility.
