Description DEEPSOIL is a one-dimensional site response analysis program that can perform both 1-D nonlinear and 1-D equivalent linear analyses. The main features of the 1D equivalent linear analysis are: Unlimited number of layers / material properties / number of acceleration data points of input ground motion; 3 types of complex shear modulus. The main features of the 1D nonlinear analysis are: Confining pressure dependent soil model; 4 types of viscous damping formulations; Pore water pressure generation (Matasovic and Vucetic, 1993, 1995; Green et al.,2000)/dissipation capability. The main features of the graphical user-interface are: Visual selection of optimum modes/ frequencies of the viscous damping formulation; Visual selection of nonlinear soil parameters: Once the nonlinear soil parameters are selected, G/Gmax and damping ratio curves can be calculated / displayed and compared to selected reference curves; Allows both English and metric units; Animation of horizontal displacement of the soil column (only for time domain analysis); Convergence check (only for equivalent linear analysis): it displays the maximum strain profile for each iteration in performing equivalent linear analysis (this feature allows checking of whether the solution has converged); PGA profile; it displays acceleration, strain, stress time histories, Fourier response spectrum, Fourier amplification ratio spectrum, and response spectrum at selected layers. It is also possible to export output into text files; it can convert NEHRP Site class A motion to Site class B/C motion and vice versa; it can baseline correct any motion in the library; Output data is automatically exported for future reference.
