Abstract
The objectives of this research work are: 1- Developing a parametric study for the bolted/riveted joints i.e. changing numbers of bolts/rivets (1-7) , bolt/rivet diameters (10, 16, 22 mm) and crack length to understand the behavior of cracked and un-cracked steel riveted/bolted lapped joints such as, load transfer, stress concentration factor, stress intensity factor, crack tip plasticity. 2- Examine the notch affected zone which was studied in the literature for free notch to bolted holes in the steel lapped joints. 3- Study the crack path of a crack emanated from bolted connection. 4- Developing a parametric study to study the effect of clamping force and friction coefficient on SCF and SIF for the riveted/bolted connections. 5- Developing a validated numerical finite element model for El-Ministerly Bridge through comparing their results with the field strain measurements, to validate it. 6- Evaluating El-Ministerly bridge fatigue life through the field strain measurements and the numerical modeling.
