QUESTION-1) The tension element Tu, which consists of one L80x80x5 corner bracket, which is connected to the 15 mm thick flag plate with 2 bolts, is exposed to the axial tensile force. Flag plate and corner rail are manufactured from $235 grade steel. All bolts used in detail are of M20 and 8.8 quality and 7% more than the minimum pretension force has been applied to the bolts. Standard circular holes defined in the regulation are used in all bolts and the slip plane of the bolts corresponds to the threaded body section. All dimensions given in the figure are in "mm". a) Check whether the bolt placement complies with the limits given in the regulation. (15 Points) b) Determine the maximum Tu force that the corner can carry according to the YDKT method. (75 Points) (Note: In solving the problem, you need to determine the Tu force by taking into account the frictional shear strength of the bolts and the bolt hole crushing controls, the yield and rupture strength of the corner, and the shear and block breakage situations that may occur in the corner.) 21.2 58.8 Bayrak Levhas 40 60 40 Tu L80.80.5
