A powerful computer program should be founded on advanced theory and be verified by tests and practice. The DYNAN program follows these guidelines. DYNAN is based on the improved Novak's method where a non-reflective boundary is formed between the near field and the far field to account for the mass of soil in the boundary. The program yields the dynamic response of both shallow and deep foundations under harmonic, transient, and random loadings. Such loadings can be produced by rotating or reciprocating machines, earthquake, wind, blast, sea waves, and other sources.

Features:
The program employs well-established analytical solutions for soil-structure interaction under dynamic loading conditions.
Analyze four different foundation types
footing supported on a homogeneous half-space (halfspace)
footing supported on homogeneous layer (stratum)
footing embedded in layered medium (multilayer)
deep foundation (pile option)
Developed based on the improved Novak method and a non-reflective boundary is formed between the near field and the far field to account for the mass of soil in the boundary zone.
For practical design purposes, the foundations (or caps on piles) are assumed to be rigid, and all six degrees of freedom are considered as coupled.
The group effect of piles is accounted for by using the method of interaction factors in the DYNAN program.
Analyze response due to constant amltitude or frequency dependent (quadratic) harmonic excitation
DYNAN can be used for the dynamic analysis under transient and random loading in the time domain (see Han and Cathro, 1997). It also can be used for harmonic loading in the frequency domain.
The program generates the output data for each frequency of harmonic loads on the foundation.
