ABSTRACT:
A building structure and method provides a cast floor supported on columns, the floor including a bottom surface having a dome-shaped region supported by at least three of the columns, the floor having a thickness that gradually increases in all directions outwardly from a crown in the dome-shaped region. The floor is reinforced by post-tensioning members that sag from near a top surface at polygonal cell region boundaries, the corners of which are at the columns supporting the dome-shaped region, to near the bottom surface for compressively stressing the cast material and upwardly biasing the floor. The floor is economically constructred using modern fly-form modules equipped with dome-shaped formwork.
