FREW

Frew is the ideal tool for embedded retaining wall analysis. It 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.
Key Benefits: Graphical entry/view of data enables easy checking of complex problems. Quick problem setup and revision with unique stage 'memory' feature. Workflow functions to simplify storage, retrieval and distribution of important documents. 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. Key Product Features: 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.
