The paper presents the results of an experimental as well as analytical investigation on the behavior of square hyperbolic-paraboloid (hypar) shell, subjected to uniformly distributed load and clamped all along the boundaries. The experimental investigation involves casting and testing of a microconcrete model of size 1000 mm×1000 mm, rise 222 mm and shell thickness 15 mm, clamped along all the four edges. The experimental results within elastic limit are compared with the results of a finite-element analysis using a doubly curved triangular shell element. The model was tested to destruction to study the behavior of the shell at ultimate load stage.
