Abstract
In this paper two numerical analysis methods (i.e. cyclic time history and pseudo-static) are applied to simulate the seismic behaviour and failure mechanism of soil-nailed structures. The numerical simulations are performed by using a finite difference software (Flac). Nevada sand soil parameters are used and construction sequences of nailed-structures are simulated prior to the cyclic and pseudo-static analyses. The results revealed that the failure pattern of two kinds of analyses are approximately similar and comprised of bilinear sliding surfaces. Furthermore, good agreement is found between failure pattern of two types of numerical analyses and previous experimental tests. based on comparison between facing displacements in two considered analysis methods, a simple process is presented to achieve the seismic coefficient consistent with the peak ground acceleration. Presentation of considered method is based on supposition that failure occurs at the constant pullout displacement of bottom-row nails for both analysis methods.
