Bolted end-plate joints have always been a suitable solution for Rectangular Hollow Section (RHS) tension members jointed on building site. In such joints bolting can be provided only along two sides or along all four sides of a hollow section. This paper deals with the joints bolted along two opposite sides (Fig. 1). EN 1993-1-8 [1] does not give recommendations for calculation of resistance of such joints. The suitability of EC3 model used for I and H (IHS) section joints with extended end plate to design of RHS joints is questionable. The main difference between bolted IHS and RHS end plate joints is yielding of RHS adjacent to the hogging plastic hinge and participating in the general failure mechanism. Design models from relevant AISC [2] and CIDECT [3] Design Guides can be used with modification of partial factors according to Eurocode. In this paper joints with ‘intermediate plate behavior’ are investigated. Joint resistances are calculated using models from [1], [2] and [3] and compared with test results from literature [4], [5]. Indicator of model accuracy is mean of test to predicted ratio and coefficient of variation. A better comparison can be achieved by calculating reliability index of joint by means of probabilistic analysis and comparing with target reliability index target. In reliability analyses it is important to consider the uncertainties in the calculation model as well as the uncertainties in the resistance parameters and applied loads. |
