Abstract:

Finite element models for the Shippingport Vertical Lift Bridge over the Illinois River at LaSalle were created using a three-web design for the sheaves. The models used a linear load distribution along the periphery of the sheave. Models were created that include details of the outer web, inner web, and hub. Using an analysis developed at the University of Illinois, 4/5P downward loading and l/5P per side was used for loading each semi-circular channel. The models were additionally rotated 18° for maximum loading. Peak tensile stresses generated in the cable tray were at 7 .2 ksi, and the peak tensile web stress was 2.6 ksi. A hub analysis was also conducted using an internal pressure of 4,000 psi generated by shrink fit of approximately 0.010 inches interference between the hub and trunnion shaft. Peak tensile stresses generated by 4,000 psi interference pressure in the forged ASTM A668 Class Chub were 10.7 ksi internal and 7.2 ksi external.
