Graduate seminars and lectures by visiting scholars supplement formal courses.
Structural engineering is the science and art of designing, analyzing and constructing buildings, bridges and other structures to safely resist various forces and conditions. Through analysis and testing of structures and their components, structural engineers advance the understanding of structural response to seismic, wind, gravity and other loads, to design more functional and economical structures. Structural engineering overlaps strongly with structural mechanics, which focuses on the application of fundamental concepts in solid mechanics to problems in structural engineering, and especially on the mathematical modeling of the behavior of both traditional and advanced structural materials. Often, the computational tools used by structural engineers draw heavily from structural mechanics.
At UC Davis, the Structural Engineering and Structural Mechanics (SESM) Group is heavily engaged in both computational and experimental approaches to address issues in structural and solid mechanics. Ongoing research in the SESM group addresses structural and non-structural materials and systems, and encompasses virtually all relevant size-scales including micro-structural, structural component, and structural system levels.
The SESM group at UC Davis is widely recognized worldwide as an international leader in the area of structural and computational mechanics, and has had significant academic and professional impact far beyond the country’s borders. Moreover, students and researchers in the group come from all corners of the world.
In the computational area, recent research has included the development and application of advanced finite element and constitutive modeling techniques, cumulative damage assessment of structures, characterization of structural behavior under earthquake loading; centrifuge modeling studies for soils and soil/structure interaction. Other areas of research include computer-aided design; development of ductile structural systems and retrofit of non-ductile systems for enhanced seismic performance; non-destructive evaluation of material properties and computational modeling techniques for fracture and fatigue in steel and concrete structures.
The computational and experimental efforts of the group often complement each other, and recent large scale experimental projects and analytical studies have focused on a variety of problems, including
the response of approach slabs in highway bridges
the behavior of extended pile-shafts subjected to earthquake loads
the seismic behavior of steel braced and moment frames, strength of welded connections
low cycle fatigue and buckling of reinforcing bars in bridge piers
development of material and performance models for degrading concrete structures
the influence of vertical ground motions on highway bridges
The group also enjoys a strong collaborative relationship with the Geotechnical Engineering Group. Research projects of common interest to both groups include geotechnical-centrifuge studies of soils and dynamic soil-structure interaction; constitutive modeling of soils and reinforced earth, and response of sites to seismic phenomena.
The SESM group is well supported through numerous research grants from federal and state agencies (including the National Science Foundation, California Department of Transportation, American Institute of Steel Construction, the Pacific Earthquake Engineering Research center, among others) and is constantly in the process of recruiting high-caliber graduate students at the masters and doctoral levels. In addition to research assistantship positions, various other forms of funding are typically available (based on the candidate’s qualifications) to support graduate students through their research and education in the SESM group. Outlined below are the specifics of various research areas and faculty interests.
