Description	Characteristics Method Applied to Soils. CHARSOIL is an application of the method of characteristics for calculating 1D dynamic behavior of soils. A constant thickness zoned soil may consist of layers each having specific properties, shear modulus, density, maximum shearing strength, and viscoelastic coefficient. Underlying the soil is a rock base which may be horizontal or inclined. Dynamic excitation of the soil is introduced at the rock-soil interface by shearing stresses produced by rock motions. At the upper surface of the soil a slab may be included to simulate the dynamic influence of the weight of a building. Response of the soil can be evaluated on the basis of elastic, viscoelastic, or nonlinear (Ramberg-Osgood) soil behavior and plastic slip can be included. Information printed out includes shear; velocity (and slip velocity); displacements (and slip displacements) at each section; acceleration of ground surface; and information for plotting a hysteretic shearing stress-shearing strain curve at any layer.
