Research Experience for Undergraduate Students in Large Structural Systems at Lehigh University

The Center for Advanced Technology for Large Structural Systems (ATLSS) at Lehigh University, with support from the Pennsylvania Infrastructure Technology Alliance (PITA) offered summer fellowships for research at the ATLSS Center. The fellowship was for undergraduate students in their junior year or beginning their senior year of college in civil engineering with interests in the areas of structures, materials, or construction. The program description is provided below.

Program Outline:

  • Ten-week research experience with a stipend of $3700 (June 2 - August 8)
  • Opportunity to work on an interesting engineering topic in the area of structures, materials, or construction.
  • Work under the mentorship of a faculty member or research engineer and a graduate student
  • Participate in workshops on how to write technical reports and how to give effective presentations.
  • Visit structural engineering companies and construction projects.

In the summer of 2003 a 10-week program was held to expose undergraduates to research in the area of structural engineering. The students were recruited from Lafayette College, Notre Dame University, Lehigh University, Morgan State University, the University of Puerto Rico, and Purdue University. These students participated in ongoing research projects at the ATLSS Center and toured structural engineering projects in Pennsylvania, New York, and New Jersey. This report summarizes the REU program and presents the research of the students involved. The titles of the research reports follow:
