Abstract EN
Ship-to-shore (STS) container gantry cranes, used at terminals for loading and unloading containers from a ship, are an important part of harbor structures.
The size and weight of modern STS container cranes are increasing to satisfy the demand for bigger ships.
This is expected to result in more lateral load when excited by seismic motions.
The existing Korean STS container cranes did not behave properly during several recent moderate earthquakes in South Korea.
Typical Korean STS container cranes must be checked for the earthquake-resistant capacity.
In this research, two nonlinear static analyses procedures, also known as pushover analyses, commonly used for seismic design of buildings, namely, capacity spectrum method and equivalent linearization method, are comprehensively studied to check their suitability for studying seismic behavior of STS cranes.
Results obtained by these two nonlinear static analysis methods are then compared with the results obtained by nonlinear time-history analyses of the STS cranes by exciting them with nine recorded earthquake time histories around worldwide.
The behaviors of the cranes are analyzed in terms of the total base shear, drift, and base uplift.
The comparisons indicate that the nonlinear static methods can be appropriate for estimating the total base shear and drift of the portal frame of a container crane.
The pushover analyses also provide information on performance levels as defined in ASCE/SEI 41-13, of a typical Korean STS container crane.
Furthermore, it is observed that the uplift response of the crane is strongly influenced by the duration of an earthquake.
