The German vs. Spanish Tradition of Thin-Shell Roof Forms

Description: Themes: Origins of thin concrete vaulted forms in Germany and the US; Mathematical versus experience driven thin shell construction; Franz Dischinger, Ulrich Finsterwalder, and Anton Tedesko; Right form versus wrong form in thin-shell construction.

Learning Objectives: Students should be able to: Describe classical forms for vaulted/shell structures (domes, barrels); Introduce Anton Tedesko credited for bringing vaulted/shell structures to the US; Describe some of Tedesko's greatest works (Hershey Ice Arena, St. Louis Airport); Identify consequences of selecting the wrong form for a vaulted structure; Contrast the vaulted forms developed in the German tradition to those in the Spanish Tradition, and outline the difference in approach that led to these forms; Discuss the influence of Anton Tedesko on vaulted/shell structures and describe some of his greatest works; Examine the role fo curvature in creating stiffness in shell structures; List some of the elements that Torroja incorporated to increase the efficiency and elegance of the Zarzuela Race Tracks.
