Outline Washington University • Equipment • Coursework • Undergraduate Research • Outreach UCIST • Equipment Selection & Purchase • Outcomes • Timeline • Evaluation

Washington University GOALS: To provide students at Washington University with: • an understanding of structural dynamics • exposure to innovative structural control techniques • experience with modern laboratory equipment and instrumentation APPROACH: • purchase instructional shake table lab stations • integrate earthquake engineering experiments into undergraduate and graduate curriculum • provide opportunities for undergraduate research

Equipment

Curriculum Development • CE 146: Introduction to Civil Engineering: basic concepts in structural vibrations • CE 336: Mechanics of Materials Laboratory familiarize students with instrumentation develop an understanding of natural frequencies, mode shapes, and damping ratios • CE 550: Structural Dynamics compare mathematical model and experimentally obtained responses • CE 590: Experimental Methods in Structural Dynamics new course with experimental modal analysis, system identification, and structural control

Undergraduate Research Development of control circuit for shake table Development of demonstration of seismic effects of building contents

Outreach

University Consortium on Instructional Shake Tables GOALS: To provide: • students with an an understanding of structural dynamics • non-engineering students with exposure to the potential consequences of earthquakes • other universities with effective laboratory exercises APPROACH: • purchase instructional shake table lab stations • integrate earthquake engineering experiments into undergraduate and graduate curricula

Organization and Planning UCIST originally consisted of 23 Universities affiliated with the three national earthquake centers (PEER, MCEER and MAE) Each university will contribute one experiment or video to the project for distribution through web site An additional 16 universities have joined including institutions from Japan and Italy Each university will incorporate at least three experiments into their curriculum

Equipment Selection and Purchase A task force of faculty from member universities was formed to formulate specifications and select equipment. Accessories: • 2 story building • 3 accelerometers • Computer • Real-time control/data acquisition board • Function generator

Equipment Selection and Purchase (cont) Shake Table Power Supply Building Function Generator Safety Feature

Outcomes Classroom experiments with lab manuals Videos of select experiments Undergraduate and school children competitions CD-ROM of experiments and videos (web page) Undergraduate research projects Outreach projects

Examples of experiments to be developed • Basic Concepts in Structural Dynamics • K-12 Outreach Activities in Earthquake Engineering • Demonstration of Lateral/Torsional Coupling in Buildings • Seismic Response of Building Frames • Demonstration of Non-Structural Seismic Hazards in the Home • Dynamic Behavior of Simple Soil-Structure Systems • Web-Controlled Shake Table • Demonstration Experiment of Sloshing Fluid Damper and Tuned Mass Damper

Timeline Fall 1999 Spring 2000 Summer 2000 Fall 2000 Spring 2001 Deliver Shake Tables Prototype Testing Funding Obtained Develop Specs Develop Experiments CD-ROM Assembled

Evaluation is planned through the web site including the following tools: • each faculty/student involved will complete annual on-line surveys • web page statistics will provide external impact measures (domains, countries)
