<p>A building is constructed using parabolic arches. A tensile membrane is placed over the arches such that the membrane is in contact with the arches over a central region but extends away from the arches over a peripheral region. The membrane is secured in tension at its edges so as to define an anticlastic surface. A wall is built to present an upper wall surface above ground level and edges of the membrane are secured to the upper wall surface. A central floor area under the central region of the structure is excavated below ground level. A structure provides a large covered space for use as an arena or similar application while construction costs are substantially reduced compared to known configurations for facilitating similar applications.</p> |
