“…In particular, HR bolts were modelled as a single part, with the stress-strain curve depicted in Figure 2, but the stiffness and strength were adjusted in order to account for the nominal diameter of the bolts assumed for the geometry. This was achieved by reducing the material strength with a value corresponding to the Anom/As (nominal area divided by the tensile bolt area) ratio and the evaluation of the bolt stiffness based on the method proposed by [27].…”

-The tension type joint is a mechanically very efficient connection method, as it directly uses the load capacity of base metal or high tension bolt, the reduction of the number of drilling hole and fastening and the fatigue resistance. It is applied to the joint of girder and cross beam, horizontal joints of towers, beam to column joints, the secondary member joints of deck floor ends, and brackets. In this paper, static load tests for the T-type tension joint were conducted to investigate the structural behavior of the joint. The parameters were bolt diameter, flange thickness, and the reduction of clamping force of the joint. The failure modes and load capacity of joints and the effects of flange thickness, bolt diameter and clamping force were investigated.

This paper deals with the prediction of the monotonic and cyclic response of blind-bolted angle connections between tubular columns and open beams. Firstly, the experimental study used for validation purposes is briefly described with focus on the required connection details and material properties. A mechanical model, based on the component approach, is then proposed and a detailed description of the model assumptions, component characterization, overall considerations and model validation is presented. The proposed mechanical model is also used to perform a parametric investigation into the key factors influencing the behaviour of blind-bolted angle connections. It is shown that the blind-bolt grade, angle thickness, column face slenderness and gauge distance have a significant influence on the connection behaviour. Based on these findings, simplified approaches for the estimation of the initial stiffness and moment capacity of blind-bolted connections are suggested. Failure mode considerations and simple expressions for ensuring the desired yield mechanism are also discussed. In addition to the detailed component model, this work provides information necessary for the development of practical design procedures for blind-bolted angle connections.
