Analysis of Lowering Effects in Aluminum Single-Layer Latticed Dome with Temcor Joints

Abstract:

The numerical analysis of a single-layer latticed dome has been carried out by using ANSYS, in order to evaluate the effect of influencing factors, like semi-rigidity of joint, buckling in compressed bars, load distribution and initial imperfections, which can produce important reductions of the load bearing capacity of these kind of structures. As a case study, the use of Temcor joint has been investigated. The characterization of the Temcor joint behavior to be introduced in the global model of the dome has been done by a FE model implemented on ABAQUS. The effects of the analyzed factors on the load-carrying capacity of the dome have been identified and useful suggestions for the design of this type of structures have been given.
