Abstract

The Nebraska State Capitol in Lincoln contains some of the best examples of timbrel vaults and domes designed by the Spanish architect Rafael Guastavino in the 1930's. In this unique construction style, the thin bricks are placed flatly, forming one or more layers and they are constructed without centering or other support. In the case of a dome, the bricks are placed in concentric rings to complete a semi-sphere. During the construction, the bricks are supported by the adhesion of the fast-setting mortar to the completing walls or to the bordering walls. A half scale model of one of these timbrel domes in the Nebraska State Capitol is constructed at the Peter Kiewit Institute Structures Laboratory of the University of Nebraska. The model dome is designed according to Guastavino's original drawings gathered from the Capitol archives, and the construction procedures described in the pertinent literature are followed closely. In this article, first, the details of the construction of the model dome are presented. Then, initial assessments on the structural behavior of the timbrel dome construction will be discussed based on preliminary results of modal experiments and finite element analyses.
