James “Jim” Rossberg, who fostered a community of structural engineers and helped expand the scope of the bible for structural design loads, died this week, the American Society of Civil Engineers announced. He was 65.

Rossberg joined ASCE in 1993 as part of its Civil Engineering Research Foundation. In 1997, he launched ASCE’s Structural Engineering Institute (SEI), which today has 30,000 members. He eventually came to oversee all of the group’s institutes, as managing director of engineering programs. In the role, he also formed the Utility, Engineering and Surveying Institute.
