Report
JSCE Concrete Committee Forum on "GOOD INFRASTRUCTURE FOR THE PUBLIC, AND THE TECHNOLOGY AND TECHNOLOGY SYSTEMS SUPPORTING IT"
JSCE Concrete Committee organized a forum on "GOOD INFRASTRUCTURE FOR THE PUBLIC, AND THE TECHNOLOGY AND TECHNOLOGY SYSTEMS SUPPORTING IT" at Tohoku University (Miyagi Prefecture) on 10 September 2008 in conjunction with JSCE 2007 Annual Meeting. The coordinator and panelists are as follows:
Coordinator: Hirotaka Kawano (Kyoto University)
Presenters of topics: Satakeo Obara (Sendai resident)
Ichiro Iwaki (Nihon University)
Hiro Yokota (Port and Airport Research Institute)
Takashi Maruya (Taisei Corporation)
Yoshikazu Hoda (Newjec Inc.)Research Committee
Special Committee on Countermeasure for Damage of Tarui Viaduct (2005.5 - 2006.3)
Special Committee on Research for Damage of Tarui Viaduct (2006.7- 2008.3)
Tarui viaduct was completed in Hashimoto Wakayama Prefecture in April 2002. In October 2003, numerous cracks in the superstructure of the viaduct were found. Further investigation of the entire superstructure revealed, a large number of cracks in the top and bottom slabs and in the webs of the PRC box girders, which generated unexpected deformation in the superstructure. JSCE concrete committee established a Special Committee on Countermeasures for Damages to Tarui Viaduct. The committee planned to complete a study report after conducting an investigation on the cause of damage from the academic viewpoint, evaluating the degree of soundness, and considering the strengthening and maintenance methods.

Publication
Recommendations for Design and Construction of Concrete Structures Using Stainless Steel Bar
Stainless steel reinforcement is highly resistant to corrosion and can significantly enhance the durability of concrete structures in service under highly corrosive environments. Consequently, the maintenance costs of infrastructures with long service life can be substantially reduced and minimize the life cycle cost (LCC). With the aim of applying stainless steel reinforcement extensively to concrete structures, the Guidelines for Design and Construction of Concrete Structures (draft) have been published as the Japan Society of Civil Engineers Library 128 in August 2008.
Research committee Subcommittee on Reliability-Based Design of Concrete Structures (Subcommittee 336)
The JSCE task committee 336 on “Reliability-Based Design of Concrete Structures” (Chair: Prof. M. Suzuki, Tohoku University) was established in 2006. The objectives of the activities of the committee are to investigate the techniques for introducing reliability-based design into design codes for concrete structures in Japan and, to present the practical examples of seismic safety or durability evaluation for concrete structures based on the reliability theory.
