The built environment is becoming increasingly complex, and we face ever growing expectations by society that our infrastructure and buildings must provide exceptional performance over a long service life. The 39th IABSE Symposium provides a platform to the world’s structural engineers to share their experiences with contemporary structures and their vision for the future. The conference theme “Engineering the Future” is highly relevant today when the solutions have to be engineered using innovative technologies and past experience in a way that is economical, robust and enhances the sustainability of the built environment. The Symposium enables the participants to actively discuss practical topics related to the structural engineering of buildings, bridges and other civil infrastructure. The Symposium was organized by the Canadian Group of IABSE in collaboration with the Structural Engineers Association of British Columbia. These proceedings contain over 450 papers presented at the Symposium, which were written by an impressive roster of keynote presenters, panellists, and industry stakeholders representing design, research, construction, and socio-economic and political aspects of structural engineering. In addition, several unique workshops, tours and social events provided the participants with an enriching and engaging experience. Located on Canada’s spectacular West Coast, the host city Vancouver is one of the most beautiful and vibrant cities in the world. Its prominent location combines nature with urban life, making it an exciting conference and travel location. The Vancouver region has seen remarkable growth in recent years, with an explosion of new residential and commercial construction in the walkable Downtown core while preserving the city’s varied past. Considerable rehabilitation and expansion to Vancouver’s landmark bridges, transit structures and other civil infrastructure has also occurred in recent years. This Symposium would not have been possible without the sustained effort and the hard work of many people. Obviously, the authors, the committee members, and the reviewers are essential to the success of the Symposium. In particular, we thank the dedication of the core group of the Scientific Committee for their efforts in handling of the papers and preparing an engaging technical program, and the members of the Local Organizing Committee for making the Symposium a memorable event. We hope that you enjoyed the Symposium and find the technical program and the proceedings interesting and stimulating.
