Abstract
ABSTRACT Computational modelling has been widely used in the geotechnical field to represent soil behaviour in real problems. Most commercial programmes use the Finite Element Method (FEM) to compute stresses and deformations distributions in soils, as observed in Plaxis software. In this method, choosing an appropriate constitutive model is fundamental to obtaining accurate results. However, most models built in commercial software do not consider effects such as overconsolidation and structure, observed for natural soils with structure. The Structured Sub-Loading Cam Clay (SSLCC) model is recommended to represent this behaviour. This article aims to describe a practical methodology to code the SSLCC model to represent the behaviour of structured soils. The model was implemented in Plaxis by the User-Defined Soil Model feature and validated with experimental data of consolidation and drained and undrained triaxial tests performed for different soils. The model implemented presents good performance and can be used in the FEM interface. The methodology described can also be used to introduce any constitutive model in Plaxis.
