    ATLSS Infrastructure Monitoring Program

    Lehigh University’s ATLSS Infrastructure Monitoring (AIM) program is internationally recognized as a leader in the field testing and evaluation of bridges and related structures and continues to advance the state of the art in this field. Although the University’s structural engineering faculty, mainly under the direction of emeritus faculty Dr. John W. Fisher and Dr. Ben T. Yen, had performed countless field instrumentation projects on bridges and other transportation structures over the previous three decades, it was during the late 1990s that researchers at the ATLSS Engineering Research Center realized that the owners of various transportation systems had more definitive needs, both research and task oriented. In 2000, the operations of the Center’s AIM program formally began.


    Over the past eleven years, the AIM program’s faculty and research staff have conducted or been involved with field evaluations and failure analysis of major bridge structures and other infrastructure systems throughout the United States. Bridge owners have sought technical support for projects that included load testing and long-term monitoring of a variety of bridge types, including tied-arch, plate-girder, suspension, and truss and have often contacted the AIM program to validate the in-situ fatigue performance of a new design. The program has also been commonly contracted to evaluate the cause of observed cracking or estimate the remaining fatigue life of uncracked details. Load testing has also been successfully used to improve bridge rating analyses.

    The AIM program, currently under the direction of ATLSS Director and Joseph T. Stuart Professor of Structural Engineering Richard Sause, continues to utilize its expertise to support the engineering needs of bridge and other infrastructure systems owners throughout the United States.

    Expertise

    The expertise of the AIM program encompasses:

    • Controlled load testing and structural evaluation
    • Remote sensing and long-term health monitoring
    • Fatigue and fracture analysis
    • Development of fatigue rehabilitation and retrofit concepts
    • Modeling, simulation, and prediction of behavior through finite element analysis
    • Data reduction, analysis, and interpretation
    • Dynamic testing (forced-vibration, ambient vibration monitoring)
    • Material testing and evaluation
    Resources

    The AIM program owns a fully equipped field testing vehicle, a Dodge Sprinter S3500 cargo van with high roof and extended wheelbase, which provides extreme mobility and flexibility to respond to project demands upon short notice. This vehicle is equipped with a mobile office and stores a cache of tools, instrumentation, and other supplies regularly required for field monitoring projects.
    The data acquisition and instrumentation capabilities include:

    Rugged high-speed multi-channel digital data acquisition systems equipped with advanced signal processing capabilities

    • Rainflow cycle counting for fatigue evaluations
    • Wireless remote sensing
    • Remote data collection
    • Wide array of high fidelity sensors capable of measuring load, strain, displacement, acceleration, rotation, temperature, wind speed and direction
    • Digital video cameras with remote pan, zoom and tilt operations; a 4 channel digital video recorder (DVR) can be configured for continuous video monitoring.

  • NEES

    Real-Time Multi-Directional Equipment Site

    As part of the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) Program, Lehigh University has established the Real-Time Multi-Directional (RTMD) earthquake simulation facility at the ATLSS Engineering Research Center. The RTMD earthquake simulation facility is a next-generation earthquake research facility for seismic performance evaluation of large-scale structural systems. This facility has advanced experimental and analytical simulation capabilities to test and validate complex and comprehensive analytical and computer numerical models, leading to advances in earthquake engineering and experimental methods.


    The facility features a multi-directional reaction wall, five dynamic actuators, advanced instrumentation, and a tele-participation system consisting of real-time streaming data and video. Hydraulic power for the servo-actuator system is supplied by a system consisting of five pumps and three banks of accumulators that enables strong ground motion effects to be sustained in real-time for up to 30 seconds. Real-time multi-directional seismic testing of large-scale structural components and systems at the RTMD earthquake simulation facility can be performed using either the effective force method, pseudo-dynamic testing method, or the pseudo-dynamic hybrid testing method. Distributed hybrid pseudo-dynamic testing can also be performed using the RTMD facility in conjunction with other laboratory sites.

  • RAMP

    Research for Advanced Manufacturing in Pennsylvania (RAMP)

     

    Lehigh University’s Advanced Technology for Large Structural Systems (ATLSS) Engineering Research Center, in conjunction with Carnegie Mellon University’s Institute for Complex Engineering Systems (ICES), will administer a university-industry economic development program funded by the Pennsylvania (PA) Department of Community and Economic Development under the Discovered and Developed in PA (D2PA) Program.  The program is entitled Research for Advanced Manufacturing in Pennsylvania (RAMP). 
     
    The RAMP Program will leverage the research and innovation capabilities of two of the Commonwealth’s leading research universities, Lehigh and Carnegie Mellon, and the technology-rich manufacturing sector of PA industry, to form a unique university-industry collaboration that will lead to the following outcomes in the Commonwealth:
    • Create a program that is PA manufacturing company influenced and uses a competitive proposal process to select and enable projects that will drive innovation in PA’s manufacturing job creators.
    • Create an environment linking PA companies with students to create high paying manufacturing jobs and to interest and retain highly educated students in the field of manufacturing
    • Provide PA companies with a competitive technology edge by introducing them to researchers and universities with equipment and skill sets to which they do not currently have access;
    • Open the floodgates of technology assistance and innovation to PA companies by breaking down the barriers to academic expertise;
    • Focus the innovation and educational capabilities of PA’s world-class research universities on real-world manufacturing solutions for PA.
     
    RAMP will operate as a competitive funding program that will provide small Commonwealth funded incentive grants (approximately $25,000 to $75,000) to researcher-lead teams at PA universities that engage in specific, short-term innovation projects (1 to 1.5 years in duration) with a PA manufacturing company to rapidly develop and transfer innovative technologies that would help PA manufacturers to compete in the global marketplace.  These grants would be used to primarily support graduate students and other non-faculty related expenses at universities under the supervision of researchers who would be committed to working with PA manufacturing companies.  The PA companies would be required to provide leverage funding, targeted at $1.5 for every $1.0 of RAMP funding, for labor and project expenses to complement the funding by the proposed Commonwealth project. The results obtained by these industry-university partnership projects would also provide incentive for university researchers to seek federal grants in areas that augment the efforts initiated by the Commonwealth program and amplify the upstream investment in PA manufacturing.
     
    The RAMP program will primarily target projects with partnering PA companies that have manufacturing facilities located within the Commonwealth.
