A structural issue with its steel support system, and not an overload of snow or high winds, likely caused the gymnasium roof of Blacksburg High School in Virginia to collapse in February, according to an engineering report. The collapse began when the main truss rotated down until it broke loose from its support column. It would cost about $9 million to rebuild the gym, but that could be alleviated because the gym's floor and basement are still useful, according to school Superintendent Brenda Blackburn.
