Abstract
This paper presents the results of experimental study of the prefabricated concrete funicular shell units subjected to uniform load, compared with numerical results obtained from a Finite Element (FE) model in the elastic range. Eight concrete funicular shell units, with a specific dimension, are constructed using a double edge steel frame and a cloth membrane as the mold. Electrical resistance strain gauges are mounted on top and bottom surfaces of two of these specimens in three different locations along the diagonal of the shells. Dial gauges are also installed at several locations on the surface of the six other specimens. These shells are then loaded to different load levels in the elastic range. Average membrane stresses and vertical displacements are measured. A finite element model of the shell consisting of 400 shell elements is utilized in order to relate the experimental results to theory.
