Abstract: This paper introduces outline of systematic research on structural performance of concrete structures with material deterioration done by Technical Committee 331 in Japan Society of Civil Engineers (JSCE-331) during 2004 and 2009. It is one of the key technologies to realize ideal service life management of concrete structures to evaluate structural performance of concrete structures, namely deflection, load-carrying capacity and ductility, taking into account material deterioration, such as reinforcement corrosion, frost damage and alkali-silica reaction. JSCE-331 tried to establish scientific and technical platform to comprehensively solve these problems. Five working groups were organized in the committee from the view of experimental study on structural performance of deteriorated concrete structures, analytical study on constitutive models and nonlinear analysis of deteriorated concrete structures, on-site inspection methods for assessment of residual structural performance, reliability approach on service life management and comprehensive case study on assessment of structural performance of actual deteriorated structures by numerical simulation. Significances, difficulties and future prospects of this field of research are discussed based on the results of JSCE-331 in this paper.
