Abstract

1. Introduction:Free forms are usually used to refer double curve surfaces which are independent from groups of geometrically or mechanically constrained forms. Geometrically constrained forms are only conditioned by a geometrical definition, like it could be done on basis of simple surfaces. When there is a close relationship between forms and forces, the forms are mechanically constrained [1]. In the present study, behavior of DOUBLE DOMES FREE FORM single layer SPACE STRUCTUREs as a group of FREE FORM structures are investigated. Gaussian curvature of DOUBLE DOMES can be positive and negative, unlike regular domes. In single layer reticulated SPACE STRUCTUREs, local instability with nodal snap-through phenomenon could result in propagation in whole structure [2], so stability behavior of DOUBLE DOMES FREE FORM single layer SPACE STRUCTUREs should be investigated. The parametric study is performed in order to evaluate the effects of different variables on the stability behavior of DOUBLE DOMES FREE FORM SPACE STRUCTUREs.
