Challenging Glass 4 & COST Action TU0905 Final Conference

This proceedings volume of the Challenging Glass 4 & COST Action TU0905 Final Conference, held 6-7 February 2014 at the EPFL in Lausanne, Switzerland, represents the Final Action Publication of the European research network COST Action TU0905 “Structural Glass – Novel design methods and next generation products”. It contains nearly 100 peer-reviewed papers – published by more than 180 authors from 22 different countries – that focus on the architectural and structural applications of glass in structures and facades. As such, it provides a profound state-of-the-art of structural glass design and engineering. A must-read for all architects, engineers, scientists, industry partners and other enthusiasts interested in this rapidly evolving and challenging domain.
