Abstract

Disclosed is a structure that may include a first flange, a second flange, and a web connecting the first flange to the second flange. In example embodiments, the web may include at least one end with at least two angled members attaching to one of the first flange and the second flange and another end connecting to the other of the first flange and the second flange. Disclosed also is a wind turbine blade that includes the structure.
