In steel tubular towers flange connections are used to assemble two segments of the tower. As an alternative for the economical and technological barriers, a new type of friction connection is investigated.This connection consists of the upper tower segment, where normal clearance holes are made and where bolts are preinstalled and the lower tower segment where open slotted holes are prepared.This paper describes a method based on a three-dimensional finite element model of a single shear lap joint connection. A finite element (FE) model is developed using the non-linear code ABAQUS and a number of FE simulations are made by varying the most significant parameters which can affect the accuracy and efficiency of the model; boundary conditions, mesh density, fabrication tolerances etc.. The ability of the models to give a satisfactory representation of the assembling connection in a tower for wind turbines is evaluated. Secondary bending, which occurs because of geometric eccentricities when the element is loaded in tension, is studied by simplified analytical model and by ABAQUS.Results of FEA and resistance according to European codes, series EN1993-1-8 are considered.
