National Center for Weather and Climate Prediction
Blast design for precast facade panels of new building to house US agency headquarters. Some members load bearing, some panels sloped and curved. Anticipated LEED Silver. 268,762 sf.
Weidlinger Associates was the blast design consultant to the precast subcontractor for a new building to house the US National Oceanic and Atmospheric Administration's National Center for Weather and Climate Prediction. The new headquarters will consolidate, replace, and expand existing facilities. The site, on the University of Maryland campus, is one of the nation's largest research parks.
The project was particularly challenging, as some of the precast members were load bearing and some of the precast panels were curved and sloped. Weidlinger performed inelastic dynamic single-degree-of-freedom calculations for the precast facade panels to confirm that the components were adequately reinforced to resist both directly applied and superimposed blast loads. The firm also provided connection design forces to the precast subcontractor and worked closely with the precaster to develop the connection designs. The project is a candidate for LEED Silver certification and for approval as an EPA Energy Star building.
