  • Interactive IABSE – COST Actions Workshop in Zagreb

    The Value of Structural Health Monitoring for the reliable Bridge Management

    At the beginning of March 2017 an interesting workshop took place at the Faculty of Civil Engineering of the University of Zagreb. The Workshop was organised by two European cooperation and networking projects under auspices of the COST framework and the Working Commission 1 of IABSE.

    The workshop gathered 120 participants from 40 countries and was organised through three main sessions:

    •   Performance assessment of existing Bridges for their reliable management;

    •   Framework, Strategies and Tools towards the Quantification of the Value of SHM;

    •   Management and Performance-assessment of Existing Structures

         The workshop in Zagreb gathered 120 participants from 40 countries with different professional background

    • Four important keynote lecturers were sharing their knowledge on assessment, monitoring and life cycle management of bridges:
    •   Dan M. Frangopol from the Department of Civil and Environmental Engineering at the Lehigh University in USA lectured on Risk-, Resilience- and Sustainability-Informed Decision Making for Bridges in a Life-Cycle Multi-Objective Optimization Context;

    •   James L. Beck from the Dept. of Computing & Mathematical Sciences at the California Institute of Technology in USA introduced participants to Bayesian uncertainty quantification and sparse Bayesian learning for model updating in SHM;

    •   Ho-Kyung Kim from the Department of Civil and Environmental Engineering at the Seoul National University in South Korea shared the experience in What We Have Learned from Operational Monitoring and Serviceability Assessment of Long-Span Bridges and

      Hitoshi Furuta from the Faculty of Informatics at the Kansai University in Japan gave an overview of New Technologies for Condition Assessment of Existing Structures.

    Keynote presenters from Lehigh University in USA Frangopol; from California Institute of Technology in USA Beck; from Seoul National University in South Korea Kim and from Kansai University in Japan Furuta, shared their knowledge as external advisors

  • 2016 KIBSE conference

     The 2016 conference of the Korean Institute of Bridge and Structural Engineers was held at Mok-po National University on October 10th-11th, 2016. Professor Kim attended session one, in which Professor Sim of Chung-Ang University made a presentation entitled "Inspection and Mechanical Characteristics of Corroded Prestressing Steels" (Sim and Kim et al.).

     Uniquely, there was a 'Young Engineer Session' aimed at encouraging researchers of Ph.Ds, or Ph.D-course students of 33 years or younger at this year's conference. Ph.D course student Sun-Joong Kim of our laboratory participated as one of the speakers, presenting "Stabilization of Identified Damping from Ambient Vibration Test by Amplitude-Modulating Function". And, to our great joy, he won 1st prize in the contest.


     There was also a poster session in which master's course students Kil-Ho Choi, Seok-Hee Bong, Lee-Sak An, and Jin-Hyung Lee participated.


    Kil-Ho Choi and Seong-Yeol Baek, "Combined Use of Active Turbulence Generator for Simulating Large-Scale Vertical and Longitudinal Wind Velocity Fluctuations".


    Seok-Hee Bong, "Residual Life Estimation of Pitting-Corroded External Tendon".


    Lee-Sak An, "New Introduction of Cable Part in Korea Highway Bridge Construction Specification"


    Jin-Hyung Lee, "Dynamic Effect of Water Tank on a Cable-Supported Bridge".


     On the 2nd day of the conference, there was a field trip to 'sae-cheon-nyeon bridge' in Mok-po. We visited two construction fields where different construction companies are under construction currently. The first field, a three-pylon suspension bridge(length : 3640m), was being constructed by 'Daelim'. And, the second field, a cable-stayed bridge(length : 3584m) was being constructed by 'Daewoo E&C'.

  • KSCE 2016 Convention
    This year’s Korean Society of Civil Engineers civil expo and conference was held in Jeju International Convention Center last October 19-21, 2016. 


    Professor Kim Ho-Kyung participated in a special session where he introduced the outline of research projects that aim to develop technologies for risk assessment of cable bridges and constant securement of resilience against natural and man-made disasters. He also presented the research on proposed guidelines for the vehicle safety and roadworthiness of the cable stayed bridges during high wind conditions. 

    PhD student Han Sung-Wook also had his presentation in a separate session with a title: “Wind-resistant design of noise barriers in expressway”. 

    Meanwhile Kim Se-Jin participated in the thesis poster event with an entry: “Probabilistic estimation of frequency of wind-induced vehicle accident on a bridge for cosswind”. 

    Lastly, Ralph Acebedo participated in one of KSCE’s international programs, the Civil Engineering Leader’s Network (CELeN) meeting.
