Automated CPT interpretation and modelling in a BIM/Digital Twin environment

Following up on previous research on Automated Parameter Determination (APD), in which the soil stratification and numerical model parameters are automatically derived from individual CPTs, this article describes ongoing research in which the geotechnical modelling workflow is further automated in a BIM / Digital Twin environment. Especially in...

Evaluation of relative density effects on liquefiable sands using PM4Sand model

To simulate the behaviour of saturated sands under cyclic loading, the PM4Sand constitutive model (version 3.1) formulated by Boulanger & Ziotopoulou [1], is used. The model can realistically reproduce the pore pressure build-up, accumulation of strain as well as triggering of liquefaction. The effect of dif-ferent relative densities on...

Evaluation of relative density effects on liquefiable sands using PM4Sand model

When saturated soils are subjected to an earthquake, the excess pore pressuresincrease, and, in the case of sands, this may cause liquefaction. To simulate the behaviour of saturated sands under cyclic loading, the PM4Sand constitutive model (version 3.1) formulated by Boulanger & Ziotopoulou (2017), is used. The PM4Sand model represents an...

A Constitutive Model For Masonry Structures: Practical Application Under Earthquake Loading In Groningen

In this paper, a constitutive model for masonry structures is presented. It is based on the Jointed Rock (JR) model with overall Mohr-Coulomb (MC) failure criterion, and it is implemented as a user-defined soil model in the finite element<br/>code PLAXIS. The Masonry model is a linear elastic-perfectly plastic model capable of simulating the...

Implementation, Validation, and Application of PM4Sand Model in PLAXIS

This paper presents the implementation, validation, and application of the PM4Sand model (version 3) formulated by Boulanger and Ziotopoulou (2015) in the PLAXIS finite element code. The model can be used for modelling geotechnical earthquake engineering applications, especially in the case liquefaction is likely to occur. The PM4Sand model...

Simulation of thermal cycle aging process on fiber-reinforced polymers by extended finite element method

The simulation of long life behavior and environmental aging effects on composite materials are subjects of investigation for future aerospace applications (i.e. supersonic commercial aircrafts). Temperature variation in addition to matrix oxidation involves material degradation and loss of mechanical properties. Crack initiation and growth...

A practical study on the induced seismicity in Groningen and the seismic response of a masonry structure

In this paper the man-induced earthquakes in Groningen (the Netherlands) are studied in terms of site response analyses and liquefaction evaluation. A particular soil profile in Loppersum is employed and soil properties are determined based on available geotechnical data. Clayey soil layers are modelled by means of the Generalised Hardening Soil...
