Analysis of steel connections with girder clamps according to the bolts preload
Abstract The use of reconfigurable and removable structures in industrial facilities is an adequate solution to reduce the costs of new investments and generate less waste, reusing existing structures and infrastructures as much as possible. Steel connections using girder clamps is a promising technique in this regard, but there is a lack of research work on these constructive systems. A key point in the behaviour of this type of joints is the preload applied to the bolts. This paper presents the analysis of the deformation of steel connections using girder clamps according to the preload applied to the bolts and the geometrical characteristics of the clamps. For this purpose, an analytical model based on the Eurocode is proposed. The analytical model has been compared with a FEM (Finite Element Method) based numerical model as well as with experimental tests. The results obtained indicate that for the maximum displacement values the difference between the predictions of the analytical model with respect to experimental testing did not exceed 12%. A detailed analysis of the behaviour of the joint with girder clamps according to the preload applied to the bolts as well as the geometrical characteristics of the clamps was also performed.
Highlights Clamp joints are a promising technique to build reconfigurable and removable structures. A key point in the mechanical behaviour of steel connections using girder clamps is the preload applied to the bolts. An analytical model based on the T-stub methodology is proposed for the study of the deformation of this type of joints. Good agreement between the predictions of the analytical model with respect to experimental testing was found.
