Frew
Analysis of the behaviour to inform the design of flexible retaining wall-like structures.
What is Frew
Embedded flexible retaining wall analysis
Oasys Frew is designed to analyse the behaviour of flexible retaining wall structures. By utilising both Limit Equilibrium and pseudo-finite element calculation methods, Frew delivers a validated and reliable solution that is straightforward to use. Its robust calculation capabilities and ability to model multi-stage construction provide valuable results for designing embedded structural elements. This helps to streamline collaboration between geotechnical and structural engineers, ensuring the curation of reliable design options.
Study the deformations of, and stresses within, the structure through a specified sequence of construction which usually involves the initial installation of the wall, followed by a series of activities such as; variations of soil levels and water pressures, the insertion or removal of struts or ground anchors and the application of surcharges.
Benefit from interoperability with Oasys Greta for comprehensive retaining and gravity wall design and analysis and Oasys XDisp to produce more advanced models – the outputs from Frew can be used to inform modelling of excavations.
Core capabilities
Soil structure interaction assessments
Calculate displacements, earth pressures, bending moments, shear forces and strut (or anchor) forces occurring at each defined construction stage when analysing flexible earth retaining structures such as sheet pile and diaphragm walls.
Advanced analysis
Model complex analyses such as sloping ground and berms, seismic loading, undrained to drained transition, wall relaxation and creep, props and anchors, integral bridge analysis to PD6694.
Partial factor analysis
Apply partial factors according to EC7, AASHTO, Direct Kp, Ciria C580 or add custom parameters.
COM interface
You can use the COM interface in several innovative ways such as carrying out sensitivity analyses and automating outputs to produce comparison graphs.
Why choose Frew
With Frew, model set up is simple, it uses robust methods of analysis and provides comprehensive and transparent outputs for reporting.
We’re updating our flexible retaining wall analysis solution, building on capabilities within Frew and bringing them to cloud for intuitive modelling, enhanced design optioneering, and more detailed analysis. For routine analysis choose Oasys Gofer, and for more complex analysis choose Frew, depending on your project requirements.
