Oasys Frew 19.0

Frew is the ideal tool for embedded retaining wall analysis. It checks the stability of cantilever and propped retaining walls, predicts the displacement, shear forces, and bending moments of the wall and calculates the earth and water pressures on each side at each construction stage.
Suitable for sheet pile, secant, contiguous or diaphragm walls, it supports the latest building standards and is relied upon by leading engineering firms worldwide.
Main features:
- Define and solve even the most complex problem quickly and simply using the combination of graphical and tabula data entry
- Calculate the required wall embedment length using a choice of methods
- Quick problem setup and revision with unique stage 'memory' feature
- Model sheet pile corrosion by varying the stiffness down the wall
- Fast analysis with high quality and flexible output
- Export results to Excel for post-processing
- Models staged wall construction including excavation, filling, dewatering, struts, anchors, surcharges and changes in soil or wall properties
- Limit equilibrium analysis with the soil modelled as an elastic continuum, using either the Mindlin equations or flexibility coefficients derived from finite element analysis
- Restricts the earth pressures to lie within the active or passive limits. The effect of arching can be included by allowing redistribution of earth pressures
- Rigid (vertical) boundaries at user-specified distances from the wall enable constrained models
- Approximation of any vertical distribution of soil Young's modulus
- Practical engineering features such as partial factors (EC7, BS8002, user-defined, or direct Kp), passive softening of cohesive material and specification of minimum equivalent fluid pressure
