| Abstract: |
A performance-based aberrant vessel collision analysis was performed to access the vulnerability of the in-water anchorages of a suspension bridge, using the LS-DYNA software package. Simplified models of the design vessels were digitally launched at finite element models of the anchorages. Failure was defined as either penetration of the vessel through the outer curtain walls or undermining of the main cable saddle supports. The damage to the reinforced concrete was given in terms of plots of maximum principle strain after impact, and before and after plots of stresses in the buttresses supporting the cable saddles. Video simulations of the impacts were also generated. |
