Abstract:

This paper reports on experiment and numerical analysis relating the buckling of a single layer latticed dome under uniformly distributed nodal gravity load at the dome central portion. The effect of a half open angle subtended by a member on buckling load and buckling behavior of single layer latticed dome is discussed. The applicability of the discrete treatment method adopted in this study is also discussed, with regard to calculating the buckling behavior of a single layer latticed dome occurring the member buckling and dimple buckling.
