Analysis of prefabricated steel dome nodal connection behaviour
Abstract
The behaviour of a steel geodesic dome node, optimised from the aspect of its assembly, is characterized in the paper. It is an overlap connection with one bolt, where tubular members are flattened and additionally bent to obtain the required dome configuration. Results obtained by means of original laboratory testing and numerical analyses are compared with analytic values determined via simplified expressions for calculation of cross sectional resistance, i.e. govern failure mode. A structural solution is recommended in order to improve this dome connection behaviour and optimise the structure as a whole.
