Dr. Purasinghe is a Professor of Civil Engineering at California State University at Los Angeles and coordinates Freshman Civil Engineering Design and Capstone Design courses as well as Computer Aided Structural Analysis/Design and Experimentation Lab.
John E. Shamma is the Facility Planning Team Manager for the Metropolitan Water District of Southern California overseeing Metropolitan’s infrastructure reliability and vulnerability investigations. He was the Project Engineer for the Inland Feeder Water Conveyance System’s Arrowhead Tunnels project from 1993 – 2005. He was responsible for the design and construction of two 12 foot diameter tunnel segments totaling approximately 11 miles in the San Bernardino Mountains. Prior to his work on the Inland Feeder Project, he served as design manager for a multitude of projects within Metropolitan’s engineering group. A registered professional engineer in California, he earned bachelor’s and master’s degrees in civil engineering from the California State University, Los Angeles. He also earned a master’s of Science in Environmental Engineering from the University of Southern California. Since 1999, he has served as an adjunct professor of civil engineering at California State University - Los Angeles.
Howard Lum is a Registered Civil and Structural Engineer in California. He is currently the Team Manager of Facilities Design Team at Metropolitan Water District of Southern California. He is an adjunct faculty member at California State University in Los Angeles.
Bringing Current Research to Classroom using Study of Earthquake Response of Buried Pipelines: An Interactive Approach to Vertically Integrated ClassroomsAbstractThis paper describes a hands-on and demonstration driven learning opportunity at theundergraduate level for the students to understand and experience the behavior of buried waterpipelines in seismic regions. This research was brought to freshman design, a junior levelstructural analysis/design, and experimentation and a graduate level structural engineeringclassroom, by vertically integrating coursework with a i) analysis and design project, and ii) astructural testing of a pipeline segment at the laboratory. The design project uses cellularconcrete to simulate a friction-confined boundary condition at earthquake fault locations. Thestudents built structural computer models of the buried pipeline at a strike–slip fault andphysically tested pipe segments in the structures laboratory. The load-deformation laboratorytests were designed and conducted through a collaborative effort of professional practitioners,industry specialists, faculty, and students. The tests aim to demonstrate how pipes deform whensubject to transverse loads, similar to the lateral movement experienced at an earthquake fault.Students are able to grasp the concepts of pipeline design for earthquake resistance, and learn tounderstand inelastic nonlinear response caused by large seismic deformation through a hands-onmodel. Through the analysis/design project and the experiment, undergraduate and graduatestudents understand the concept of how improvements can be made to pipeline design so thatstructural resilience can be improved at an earthquake fault crossing. This paper documentsdetails of the vertical integration of courseware starting from freshman level to graduate leveland effectiveness of student group work in vertically integration of classrooms. The final paperwill present details of course assessment as well as impact of the courseware for professionalpractice.
