Description
Summary:Earthquake forces, regarded as external forces, are calculated using a seismic coefficient. A simple approach - the generalised tangential technique - is used to formulate the stability problem as a classical optimisation problem. In order to see the validity of the present approach, static stability factors are compared with the solutions of Collins et al. (1988). Numerical results are presented for practical use. This paper extends the work of Chen (1975) using a linear MC failure criterion to that using the non-linear modified FIB failure criterion.
