Shake Table Experiments for the Determination of the Seismic Response of Jumbo Container Cranes
Ports have received little attention compared to other infrastructure systems such as: buildings, bridges, water, and power systems. This lack of attention is surprising 2 considering the importance of uninterrupted operations at ports. For example, a 10-day labor lockout at the ports on the west coast of the US had an estimated daily economic impact of billion (Caltrade, 2008). The 1995 Hoyogken-Nanbu earthquake, which caused severe damage to the Port of Kobe provides an example of the long term effects of heavy port damage. After the earthquake, the port struggled to make extensive repairs, and shipping companies were forced to find other ports to continue shipping operations. With little incentive for the companies to return, the Port of Kobe never returned to its pre-earthquake throughput (Chang, 2000). The city of Kobe, which was also struggling to rebuild, had to do so with a significantly reduced economic base. Therefore, with container traffic in the US expected to continue to grow, protecting the seaports from seismic damage should be a high priority.
