New Projects Underway at University of Florida
[https://www.designsafe-ci.org/media/cms_page_media/890/ufl_blwt.jpg]

Two new NSF-funded projects are ramping up for the University of Florida experimental facility.

Richard Christenson from the University of Connecticut (NSF Award 1732213<https://www.nsf.gov/awardsearch/showAward?AWD_ID=1732213&HistoricalAwards=false>) and Steve Wojtkiewicz from Clarkson University (NSF Award 1732223<https://www.nsf.gov/awardsearch/showAward?AWD_ID=1732223&HistoricalAwards=false>) recently won a collaborative EAGER award entitled, "Aeroelastic Real-Time Hybrid Simulation for Wind Engineering Experimentation."

The project will address multiple challenges associated with cyber-physical testing in a wind tunnel, including actuator compensation; stability analysis; limitations imposed by the size of the computational substructure; the increased time scale of wind tunnel models; and the type and number of sensor measurements.

Also, Delong Zuo and his colleagues at the National Wind Institute at Texas Tech University (TTU) won a CMMI award to study tornado loading effects on low-rise buildings with consideration of internal pressure (NSF Award 1663363<https://www.nsf.gov/awardsearch/showAward?AWD_ID=1663363&HistoricalAwards=false>).

The project will compare wind load measurements obtained from the Tornado Simulator at TTU<https://www.depts.ttu.edu/nwi/research/facilities/vortech.php> to measurements made on identical building models at the UF Terraformer Wind Tunnel<https://www.youtube.com/watch?v=_VKqqrQkc5k>, with the goal of characterizing the difference between nonstationary, non-neutral flows and so-called "straight line" winds.

UC Berkeley Department of Civil Engineering is pleased to announce a Retirement Symposium and Celebration honoring the career of Professor Anil K. Chopra. Mark your calendars for two-day event.

The symposium will take place on Oct. 2-3, 2017 at UC Berkeley.

Prof. Chopra retired from the faculty at UC Berkeley in 2015 after 46 years of service and currently holds the position of Emeritus Professor there. He has made fundamental and important contributions to earthquake engineering in both research and teaching.

He is well-known internationally for his popular and accessible textbook on structural dynamics. He received the UC Berkeley Distinguished Teaching Award in 1999, and has been honored extensively for his research, including: election to the National Academy of Engineering (1984) and receiving the ASCE Newmark Medal (1993) and the EERI Housner Medal (2002) - among many other honors. He is particularly well-known for his extensive work on dam analysis, and has been recognized as one of the most influential people in that area. He is also the long-time general editor of Earthquake Engineering and Structural Dynamics, the premier international journal of the field.

The symposium will feature a lineup of prominent national and international speakers who are former students and close collaborators of Professor Chopra, and they will share their research and experience in working with him.

RPI Team to Study Fluid Mechanics at the NHERI Wall of Wind Site
[https://www.designsafe-ci.org/media/cms_page_media/899/wow_control_center_email.jpg]

A research team from Rensselaer Polytechnic Institute has been awarded an NSF grant to investigate the flow mechanisms that cause very high suctions on buildings. This project is led by Chris Letchford<https://www.researchgate.net/profile/Chris_Letchford>, professor and head of the Department of Civil and Environmental Engineering at RPI, and it is titled, "Model to Full-Scale Validation of Peak Pressure Mechanisms in Buildings that Cause Cladding Failures and Windstorm Damage<https://nsf.gov/awardsearch/showAward?AWD_ID=1727401&HistoricalAwards=false>" (NSF award #1727401).

The RPI team will carry out near full-scale tests at the NSF NHERI Wall of Wind (WOW) experimental facility<https://fiu.designsafe-ci.org/> at Florida International University. The project aims to determine if current, small-scale wind tunnel-tests are able to reproduce very high suctions as well as determine which incoming flow characteristics are most critical in causing the high suctions. This project demonstrates how the NHERI WOW site can be implemented to advance fundamental fluid mechanics research.

Fundamental to wind engineering is the need to understand and model the underlying physics of flow separation that affects wind loading on civil infrastructure (e.g., buildings). Unlike any other engineering domain, these structures are not prototyped but rely almost exclusively on wind tunnel tests at vastly reduced length and lower velocity scales. Wind tunnel results are rarely validated due to the complexity of instrumenting the prototype structure and the long duration required to observe design events. Most windstorm damage to buildings is initiated with cladding failures at locations where very high suction pressures are observed on the building, typically near corners and edges where the flow separates from the structure under peak and fluctuating pressures. Wind tunnels have become ubiquitous for obtaining wind loads on all types of structures, but discrepancies between peak and fluctuating pressures generated in the separated flow regions on roofs of low-rise structures modeled in boundary layer wind tunnels and observed in the field have been long-reported.

This project will investigate the flow mechanisms that cause these very high suctions at near full-scale. From parametric studies of separating flows, the modeling criteria critical to developing these peak pressures will be isolated and the ability to simulate them at reduced scales in typical wind tunnel studies will be ascertained. In this way, accuracy of traditional wind tunnel testing can be investigated and current experimental procedures improved and verified. This detailed knowledge will provide greater confidence in wind tunnel testing and generic wind tunnel data for engineers to use, and ultimately translate to reduced windstorm damage to civil infrastructure.

Data from this project will be archived and made available in the NHERI Data Depot<https://www.designsafe-ci.org/data/overview/>.
