The RIME Group presented three papers in IABMAS 2014

Date: 7/9/2014

Dr. Hani Nassif has organized a Mini-Symposium 10 (MS-10) with three Korean colleagues, Dr. Soobong Shin (Inha Univ., sbshin@inha.ac.kr), Dr. Ho-Kyung Kim (Seoul Nat. Univ., hokyungk@snu.ac.kr), and Dr. Nam-Sik Kim (Pusan Nat. Univ., nskim@pusan.ac.kr) during the 7th International Conference on Bridge Maintenance, Safety and Management (IABMAS 2014). The conference was held in Shanghai, China on July 7-11, 2014, and over 350 papers were presented.

The conference is aiming at promoting international cooperation in the fields of bridge maintenance, safety, and management, and the IABMAS has developed into a significant association which covers all aspects related to bridge maintenance, safety, and management worldwide.

The objective of MS-10 is “Life-time perspective for design and maintenance of short, medium, and long-span bridges”. For MS-10, two sessions, 16 papers and 12 participants were prepared and presented.

Session 1 - Extended and sustainable design life of bridges (short, medium, and long-span bridges, but with more emphasis on (super) long-span cable-supported bridges)

Session 2 - Serviceability and safety assessment of bridges (short, medium, and long-span bridges).

Dr. Nassif and his RIME group presented three papers for MS-10 on July 9 in Chrysanthemum Room A. The 1st paper about the early age cracking was presented by Dr. Ye Xia who was a post-doctoral associate in RIME Group, Rutgers University until 2013. Dr. Xia is an assistant professor at Tongji University in China. The 2nd and 3rd papers about rail bridges were presented by Peng Lou who is a Ph.D. candidate in RIME Group.

Peng Lou presented two papers for the rail bridge.

Dr. Ye Xia presented one paper the FE analysis of deck cracking.

Paper 1
- Early age cracking in high performance concrete decks of a curved steel girder bridge
Ye Xia*, Hani Nassif, Dan Su, Chaekuk Na and Peng Lou

Paper 2
- Evaluation of existing railway bridges using structural health monitoring and finite element modeling
Dan Su, Hani Nassif, and Peng Lou*

Paper 3
- Modeling of train-bridge dynamic interaction system for bridges with stepped-beam cross-sections
Ying-jie Wang, Hani Nassif and Peng Lou*

Abstract for MS-10, IABMAS 2014

Infrastructure systems constitute a major part of the national investment of many countries and are critical for the mobility of their societies as well as their economic growth and prosperity. Transportation infrastructure systems, including bridges, are considered assets that should be designed, protected and properly managed. Yet, the degree of rapid deterioration and the risk of exposure to natural and man-made disasters are dangerously high. According to the U.S. National Bridge Inventory's (NBI) 2011 data, 24% of the 605,086 bridges in USA need replacement or major repairs. There is a need to develop sustainable design concepts, efficient assessment tools, and reliable technologies for the evaluation of numerous long-standing bridges. As the long-span bridges are also increasing, the extended lifetime is also demanding when considering the return of initial investment. Accordingly, the lifetime perspective for design and management of bridges should be set up in a consistent strategy. Considering these issues, the main goal of this Mini-Symposium is to help develop guidelines for the design, evaluation, assessment, and load rating of bridges by incorporating field-testing, structural health monitoring, and probabilistic methods. The Mini-Symposium will include sessions that will provide a platform for researchers from leading countries to discuss and compare various methodologies that were adopted by their respective transportation agencies and to enhance future collaboration on this subject. The current state-of-the-art and technological advances from design to management will be presented and discussed for the short, medium and long-span bridges.
