Structural Analysis of Kiewitt Dome by Using ETABS Software

Dome is a structural element in architecture that has changed its shape, functions and materials from time to time representing the advancement of human beings in mathematics and technology. Kiewitt dome consists of a series of subdivided triangles along the circumferential direction, which have common vertex at the crown of dome. On the basis of the lattice forms of upper single-layer reticulated shell, they can be called as rib-ring type, sunflower type and bird-nest type of suspen-dome. Kiewitt domes commonly used in spatial structures. Kiewitt Dome has better progressive collapse resistance than other dome. In this paper, we have analyzed 100 m kiewitt dome by using Extended Three-dimensional Analysis of Building System (ETABS) software and compared the results of maximum storey displacement, storey drifts, Stress and overturning moments. Structural performances under load combinations of bending moment, shear force and axial force are also being studied in this paper.
