Description MSheet determines the stability, deformations and bending moments of sheet piling during all stages of construction. Hydrostatic pore fluid pressure is modelled from the input of phreatic surface positions with additional excess pore pressures. Construction stages modelled as excavation or elevation of soil with the addition or removal of anchors and struts and alteration of the water table. Surcharge modelled as discrete or distributed surcharge at ground level. Distributed force load as uniform or variable in a multi-linear way. Forces and moments may be discrete or distributed force loads, directed perpendicular to the sheet piling; variable normal force along the beam axis; discrete bending moments directed out-of-plane. Rigid supports or springs for displacement and rotation. It is possible to define the horizontal displacement at the top of the sheet piling. Soil displacement may be assessed for horizontally loaded piles where the displacement of soil results in pile bending and subgrade reaction. Output: graphs and tables of displacements, bending moments, shear forces, pore pressures and soil stresses along the beam axis. Construction stages may be defined and connected to selected input data. Apply uniform or varying values for the elastic bending stiffness and normal stiffness along the axis of a vertical sheet piling. Anchors are characterised by arbitrary direction, elastic normal stiffness, zero pressure condition and limited capacity due to yielding or soil resistance. Pre-tensioning of anchors is optional. Define horizontal soil layers, in combination with an optional non-horizontal ground level. It models the soil stiffness using distributed springs and uses multi-linear relationships between horizontal stress and displacement, with different values for active and passive yielding. Determines yield values from cohesion and friction angle input, using the Culmann's, Katter or Mnller-Breslau slip surface theories. Accommodates the soil stiffness for the virgin loading state and the unloading/reloading state. It can determine the critical length of the sheet piling, by reducing the length step-by-step until instability occurs or an admissible displacement is exceeded. It verifies the safety of the sheet piling for a selected stage by applying certain partial safety factors, according to CUR publication 166. It checks if the available soil resistance is sufficient for the anchor using the Kranz theory.
