On behalf of the Korean Society of Steel Construction (KSSC), it is my great pleasure to have this opportunity to welcome you all to Jeju, Korea to participate in the 11th International Symposium on Steel Structures, ISSS-2021. The main objective of this symposium is to provide an international forum for presentation of recent advances on various aspects of steel construction and its applications to steel structures. The technical program of the symposium consists of presentations of keynote lectures, invited papers by each session organizer, and general technical papers related to mechanical and structural behaviors, analysis and design, fabrication, construction, and maintenance of steel structures such as bridges, buildings, and other industrial facilities. I would like to take this opportunity to express my deepest gratitude to the members of the International Advisory Committee, Local Advisory Committee, International Scientific Committee, and Local Organizing Committee for their valuable contributions and hard works. Special thanks are due to invited keynote speakers and session organizers in advance for their hard work which will make the Symposium very successful one, and last but not least, to all Symposium delegates for their supports and participations. I wish you to cherish the memories of this special event and have a very pleasant and wonderful time during the stay in Jeju, Korea.
