Life-Cycle of Structural Systems: Design, Assessment, Maintenance and Management contains the papers presented at IALCCE2014, the fourth International Symposium on Life-Cycle Civil Engineering (IALCCE2014), held in Tokyo, Japan, November 16-19, 2014. It consists of a book of extended abstracts (466 pp) and a DVD (2332 pp) with 312 full papers including the Fazlur R. Khan lecture, 7 keynote lectures, and 304 technical papers from 38 countries. All major aspects of life-cycle engineering are addressed, with special focus on structural damage processes, life-cycle design, inspection, monitoring, assessment, maintenance and rehabilitation, life-cycle cost of structures and infrastructures, life-cycle performance of special structures, and life-cycle oriented computational tools. The aim of the editors is to provide a valuable source for anyone interested in life-cycle of civil infrastructure systems, including students, researchers and practitioners from all areas of engineering and industry.
