- Abstract:
- :Earthquake resistance of temporary structures is inferior to that of permanent structures.A tower crane supported by a pile foundation,which is one of the temporary structures,is often used when constructing high-rise buildings.The tower crane installed in a high position may be vibrated largely by strong seismic ground motion because of its slender structure.Dynamic response characteristics of the structure with a pile foundation are greatly influenced by the surrounding ground and the foundation type as well.In current Japanese design mode,however,the seismic load is only to be defined as 20% of the weight of a crane,neither dynamic unstability of the structure nor influence of the surrounding ground type is sufficiently considered.In this paper,a series of centrifugal shaking table tests was performed to investigate the seismic characteristics of the tower crane supported by a pile foundation in soft clay.Two different weight conditions were set for the crane jib to accurately simulate practical situations.From the test results,the dynamic behaviours of the tower crane and the influenced factors were discussed.In addition,it was concluded that the weight conditions for the crane jib give significant influence on the level of pile damage and might lead to different failure patterns of the tower crane.
