Numerical Analysis of Local Joint Flexibility of K-joints with External Plates Under Axial Loads in Offshore Tubular Structures
文献摘要:
The Local Joint Flexibility (LJF) of steel K-joints reinforced with external plates under axial loads is investigated in this paper. For this aim, firstly, a finite element (FE) model was produced and verified with the results of several experimental tests. In the next step, a set of 150 FE models was generated to assess the effect of the brace angle (θ), the stiffener plate size (ηandλ), and the joint geometry (γ,τ,ξ, andβ) on the LJF factor (f LJF). The results showed that using the external plates can decrease 81%of the f LJF. Moreover, the reinforcing effect of the reinforcing plate on the f LJF is more remarkable in the joints with smallerβ. Also, the effect of theγon the f LJF ratio can be ignored. Despite the important effect of the f LJF on the behavior of tubular joints, there is not available any study or equation on the f LJF in any reinforced K-joints under axial load. Consequently, using the present FE results, a design parametric equation is proposed. The equation can reasonably predict the f LJF in the reinforced K-joints under axial load.
