NHERI Experts Mobilize for Hurricane Harvey
[https://www.designsafe-ci.org/media/cms_page_media/982/cera-sample-image.png]

NHERI hurricane and storm-surge experts have mobilized to the Gulf Coast region. The team includes Forrest Masters<mailto:masters at eng.ufl.edu> of the University of Florida, Arindam Chowdhury<mailto:Arindam.Chowdhury at fiu.edu> of Florida International University, and Clint Dawson<https://mail.google.com/mail/?view=cm&fs=1&tf=1&to=clint@ices.utexas.edu> from the University of Texas, Austin. Dawson's work was featured on CBS news<http://cbsaustin.com/news/local/ut-supercomputer-tracking-harveys-flood-risk>.

Dawson's team at the University of Texas used ADCIRC on TACC's HPC resources to generate storm-surge forecasts for Harvey. ADCIRC is a system of computer programs for solving time-dependent, free surface circulation and transport problems in two and three dimensions. The storm surge visualizations are online at chg.ices.utexas.edu<http://chg.ices.utexas.edu> and also at the CERA website at Louisiana State University: cera.cct.lsu.edu<http://cera.cct.lsu.edu>.

TACC has provided expediated access for these simulations due to the urgency of this natural hazard event as the storm bears down on the Texas coast.

Expect more updates from the NHERI team monitoring Harvey's damage to the Gulf Coast infrastructure.

Kareem Honored with Masanobu Shinozuka Medal
[https://www.designsafe-ci.org/media/cms_page_media/984/kareem.jpg]

Earlier this summer, during the 2017 conference of the Engineering Mechanics Institute of the American Society of Civil Engineers in San Diego, Ahsan Kareem<https://engineering.nd.edu/profiles/akareem> received the ASCE's Masanobu Shinozuka Medal. Kareem, the Robert Moran Professor of Civil & Environmental Engineering & Earth Sciences<http://ceees.nd.edu/> at Notre Dame, was recognized for "his contributions to the modeling of stochastic wind, waves, and earthquake loads and their effects on buildings, bridges, and offshore structures."

An active member of the NHERI Community, he is co-PI on the SimCenter and a senior researcher on the DesignSafe Cyberinfrastructure team. In June, as part of the SimCenter series Natural Hazard Engineering 101, Professor Kareem presented a talk titled, "Computational Fluid Dynamics, Simulation and Computational Tools<https://www.youtube.com/watch?v=dWtGCq1RAfI&list=PL2GxvrdFrBlmixOfsU8KB2g3NCBuYOFiv&index=2>."

Kareem's work has made profound impacts in the area of stochastic dynamics and simulation with particular applications to nonlinear analysis and modeling of offshore systems using very efficient time and frequency domain schemes under the combined action of wind, waves, and current. In bridge aerodynamics, he has offered a unified nonlinear aerodynamic/aeroelastic model that goes beyond the customary linear approach proposed by previous researchers. He has made similar fundamental contributions leading to the analysis, design, and performance assessment of tall buildings using computational, laboratory and fullscale experiments. This includes performance of building cladding and glass in hurricanes. Kareem has been actively involved in the performance based design of structures under winds and in the development of codes and standards.

In the arena of thunderstorm winds, he has advanced a new metric called the Gust Front Factor<http://gff.ce.nd.edu/int_gff.html> to account for the changes in kinematics and dynamics of the wind field. Over the last decade, he has developed a virtual organization tool called VORTEX-Winds<http://evovw.ce.nd.edu/wsLui/wsLui1_init1_noauth1.html> that provides a host of computational and experimental resources and databases on a cyberinfrastructure-based platform. Some of these resources are being enhanced and included in the Discovery Portal of the NHERI's DesignSafe.

The Masanobu Shinozuka Medal was instituted in 2013, to honor Masanobu Shinozuka, a pioneer in stochastic systems study and its applications to civil engineering, primarily through mechanical and aerospace engineering.

REU Students at UC San Diego Featured on DesignSafe Radio
[https://www.designsafe-ci.org/media/cms_page_media/985/LHPOST_1.jpg]

In episode #4 of DesignSafe Radio<https://soundcloud.com/user-426561648>, host Dan Zehner talks with UC San Diego's Darren McKay, development engineer and operations manager for LHPOST, the world's largest outdoor shake table at the Jacobs School of Engineering<http://jacobsschool.ucsd.edu/>. As part of the Research Experiences for Undergraduates<https://www.designsafe-ci.org/learning-center/reu/> program, 3 engineering undergraduates participated in a major project underway here, shaking a full scale, two-story wood-frame building<http://nheri.ucsd.edu/>.

On LH POST, researchers can "build big" and rigorously test their designs for seismic reliability. The facility is part of the NSF-funded, Natural Hazard Engineering Research Infrastructure, NHERI.

The students describe doing hands-on tasks such as setting up instrumentation for the test, applying sensors and analyzing data -- and using construction power tools for the first time. A little scary! Find out what NOT to wear when spending your summer climbing in and around a large-scale test structure. The REU experience convinced all three undergrads to pursue master's degrees in engineering.

Find out why safety is a top priority at the facility when McKay tells anecdotes about engineers who fail to follow safety protocols. Feeling ghoulish, host Dan Zehner asks everyone to tell their favorite disaster story, including one about a plane ride through a typhoon. Lastly, find out about the engineering research capabilities of the LHPOST shake table, where multi-university research projects are the order of the day, even if the schools are football rivals like Oregon State and the University of Washington.
