Richard L. Wood is award a 2017 Parents' Recognition Award  for providing support to students. Awards are presented to encourage good student and faculty relationships and provide recognition in an area often overlooked in the formal rewards system. Award quoted, "Dr. Wood inspired my soon to bo beyojnd his expectations in Structural Engineering."

A nationally featured research segment on the Big Ten Network (LiveBIG Segment) featuring damage assessment from point clouds in the the aftermath of natural disasters (earthquake engineering and wind loading). Video features Richard Wood as well as PhD students Ebrahim Mohammadi and Yijun Liao (Research Group). Prominently shown data includes the Imperial Cabinets Building in El Centro, California (2014), Wiser-Pilger Middle School following the 2014 Pilger Tornado, and Bungamati, Nepal following the 2015 Gorka (Nepal) Earthquake.  These data sets are being used to objectively detect structural damage such as cracks, spalling, and localized collapsed zones.  


Remote sensing of structural damage characterization at the Halliburton Oilfield Services plant after a late season EF-3 Pampa Tornado (Texas) November 2015.  This was remotely investigated to improve techniques to estimate wind speeds within tornadoes and other wind storms from engineered structures in collaboration with West Texas A&M (WTAMU) and Texas Tech Universities (TTU).

Team members in Pampa, Texas (from left to right):  J. Arn Womble (WTAMU), Brandon Bugarin (WTAMU undergraduate student), Richard L. Wood (UNL), and M. Ebrahim Mohammadi (UNL graduate student).  (December 2015)

Additional ongoing research collaboration with SUNY-Buffalo and Tufts University.  Here a field test is conducted in El Centro, California during November 2014 with portable shaker from UCLA.  The purpose of this test series is to develop finite element model updating techniques for damaged reinforced concrete-masonry infill buildings. 


Current ongoing research collaboration on  structural damage characterization following the 2015 Gorkha (Nepal) Earthquake was featured in a PEER webinar.  My collaborative work here included LiDAR scanning, unmanned aerial system (UAS) flights, and system identification using ambient vibration.  Details are linked here
