1. Introduction The ESIS Executive Committee decided to change the name of TC 12 in November 2016. The current name of the ESIS TC12 is Risk Analysis and Safety of Large Structures and Components (Correia et al., 2019a). One of the tasks of the ESIS TC12 Technical Committee is the organization of events for the dissemination of the technical and scientific knowledge of its members as well as other participants. The TC12/ESIS co-chairs and scientific managers have participated in the organization of various scientific events and technical meetings with similar topics (Correia et al., 2019b, 2019c; Correia et al., 2018a; Rebelo et al. 2018; Correia et al. 2017; Pariente et al., 2016; Correia et al., 2018b, 2018c, 2018d). The First International Symposium on Risk Analysis and Safety of Complex Structures and Components (IRAS 2019) was organised by ESIS TC12 on Risk Analysis and Safety of Large Structures and Components, which took place between 1-2 July 2019 at the Faculty of Engineering of the University of Porto, in the City of Porto, located at seaside in the northwest region of Portugal, (see Figure 1). This conference was intended to be a forum for discussion of the recent advances in maintenance, safety, risk analysis, probabilistic assessment, life-cycle performance, fatigue, fracture, damage mechanics, numerical simulation of a wide range of infrastructures, such as, engineering technical systems, transportation systems, bridges, buildings, dams, railways, underground constructions, wind and transmission towers, offshore platforms, pipelines, naval vessels, oceanic structures, nuclear power plants, airplanes and other types of structures including aerospace and automotive structures are considered. The IRAS 2019 event was opened with a plenary talk given by Prof. Guian Qian (Chinese Academy of Sciences, China) entitled “Application of weakest link concept to fatigue and fracture assessment” (see Figure 2a)). Invited keynote presentations were given by Prof. Hojjat Adeli (Ohio State University, USA) on “Machine Learning and Structural Health Monitoring” (see Figure 2b)), Prof. Milan Veljkovic (Delft University of Technology, Netherlands) on “Overview of TUD - Stevin Laboratory fatigue research and recent results” (see Figure 2c)), Prof. Tomasz Nowakowski (Wroclaw University of Science and Technology, Poland) on “From Reliability to Resilience: Advanced Challenges for Technical System Performances” (see Figure 2d)), and by Prof. Shun-Peng Zhu (University of Electronic Science and Technology of China, China) on “Advances in st ructural fatigue reliability design and assessment under uncertainty” (see Figure 2e)). Within 10 technical sessions, 168 talks were presented by 126 participants on various aspects of risk analysis and safety of complex structures and components (Correia et al. 2019d). The first edition of the IRAS 2019 event gathered participants from more than 20 nationalities demonstrating the worldwide acceptance of this first event. The Organizing Committee of the IRAS 2019 deeply acknowledges all authors that contributed to the success of this event, with their exciting presentations. The members of the International Scientific Committee are also fully acknowledged for their support to the IRAS 2019 event. Special thanks are also addressed to the Thematic Sessions Organizers and Plenary Speakers for their dedication and knowledge and energy brought to this event. Sponsors are also fully acknowledged for their important contributions. Finally, the guest editors sincerely thank the tireless efforts of Organizing Committee members as well as students and other FEUP (Faculty of Engineering of the University of Porto) and IC (Construction Institute) staff.
