UCSD Structural Engineering:
The vision of a Structural Engineering department at UCSD is not new, but rather carefully laid out and developed over the past 12 years. With the decision of the AMES department in the early 80’s to focus on more traditional engineering degree programs, this vision led to a B.S. degree program in structural engineering rather than civil engineering to build on the existing strength in structural mechanics and materials without the need to expand into other traditionally required civil programs such as surveying, traffic engineering, construction, waste water treatment, etc.
UCSD is highly competitive for admission, and all of its engineering majors are additionally competitive. Be sure to have actual safety schools where you are assured of admission to your desired major.
