Vcharacteristics of Seismic Response of Stepped Building Supported By Stepped Foundation on Hillside

Abstract eng:
The step back-set back building is supported by stepped foundation where the foundation elevation and roof elevation are different. The complexity of seismic input of stepped site and the irregularity of this building make seismic response of this structure has its own particularity. In this paper, a model of identical inputting wave and a model of soil-structure interaction suitable for seismic response of step back-set back buildings were developed. The dynamic response of this structure, i.e. period, storey drift, storey shear, and the shear distribution characteristic of columns have been studied by using elastic seismic response analysis method. The distribution of plastic hinges and the yield mechanism of the structures were studied by using elastoplastic analysis method. Some suggestions on seismic design for step back-set back building were presented. The conclusion will be beneficial to improve the seismic resistance capability, and promote the application of step back-set back building.
