The results of Monte-Carlo simulations are presented in terms of failure envelopes defined in VM load space for different spatial correlation lengths. The area of the soil mass affected during failure is quantified as the consequence and employed to assess the risk associated with footing failure. This study provides new insight into the behavior of an eccentrically loaded strip footing on random soil.]]> Sat 24 Mar 2018 07:33:37 AEDT ]]> Buried footings in random soils: comparison of limit analysis and finite element analysis https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26373 Sat 24 Mar 2018 07:33:06 AEDT ]]> On the efficient estimation of small failure probability in slopes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31039 pf) is small, the direct Monte Carlo simulation requires a large number of simulations. Subset simulation is one of most efficient variance reduction techniques for the simulation of small pf. It has been recently proposed to use subset simulation instead of direct Monte Carlo simulation in RFEM. It is noted, however, that subset simulation requires calculation of the factor of safety (FS), while direct Monte Carlo requires only the examination of failure or non-failure. The search for the FS in RFEM could be a tedious task. For example, the search for the FS of slope stability by the strength reduction method (SRM) usually requires much more computational time than a failure or non-failure checking. In this paper, the subset simulation is combined with RFEM, but the need for the search of FS is eliminated. The value of yield function in an elastoplastic finite element analysis is used to measure the safety margin instead of the FS. Numerical experiments show that the proposed approach gives the same level of accuracy as the traditional subset simulation based on FS, but the computational time is significantly reduced. Although only examples of slope stability are given, the proposed approach will generally work for other types of geotechnical applications.]]> Sat 24 Mar 2018 07:25:48 AEDT ]]> The bearing capacity of spudcan foundations under combined loading in spatially variable soils https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30024 Sat 24 Mar 2018 07:24:21 AEDT ]]> Determining an appropriate finite element size for modelling the strength of undrained random soils https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:22894 Sat 24 Mar 2018 07:15:18 AEDT ]]> A stochastic approach for the shear strength of rock discontinuities https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32307 Mon 23 Sep 2019 11:49:38 AEST ]]> A step towards the end of the scale effect conundrum when predicting the shear strength of large in situ discontinuities https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45484 Fri 28 Oct 2022 14:50:20 AEDT ]]> The sensitivity of bridge safety to spatial correlation of load and resistance https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24522 Fri 22 Apr 2022 10:20:38 AEST ]]> A new stochastic approach to predict peak and residual shear strength of natural rock discontinuities https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:35103 Fri 21 Jun 2019 16:08:57 AEST ]]> Non-intrusive reliability analysis of unsaturated embankment slopes accounting for spatial variabilities of soil hydraulic and shear strength parameters https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44467 Fri 14 Oct 2022 08:43:48 AEDT ]]>
