Description: Themes: Role of reinforced concrete in Robert Maillart's famous works; Maillart's early evolution of form: Stauffacher, Zuoz, Tavanasa, and Salginatobel bridges; Maillart's process of improvement on his structures throughout his career.
Learning Objectives: Students should be able to: Define reinforced concrete; Describe Maillart's evolution (imitation, innovation, inspiration) of the three-hinged hollow-box arch form; Define the deck-stiffened arch form and illustrate examples of these bridges; Describe the evolution of smooth to 'broken' three-hinged hollow-box arch forms and the 'play' of cross walls; Describe the key weakness of concrete as a building material, and explain how reinforced concrete overcomes this weakness; Contrast the structural properties of concrete and steel and explain how the materials work together to increase strength in reinforced concrete; Predict where to place the steel bars in a reinforced concrete bar used as a beam, and as a horizontal cantilever; Trace the influence of the teacher Wilhelm Ritter on Robert Maillart and Othmar Ammann (see also lecture on Ammann); Describe the social, scientific, and symbolic aspects of the Salginatobel Bridge; Trace the evolution of Robert Maillart through stages of imitation, innovation, and inspiration with examples of bridges at each stage.
