|Description:||Legacy software from 1969 evaluates the time dependent displacements and stresses of complex axisymmetric structures subjected to any arbitrary static or dynamic loading or base acceleration. Source code in FORTRAN and related reports can be downloaded from the earthquake engineering online archive maintained by University of California Berkeley.
ASHSD2: Dynamic Stress Analysis of Axisymmetric Structures Under Arbitrary Loading
Ghosh, Sukumar; Wilson, Edward L.
Department of Civil Engineering, University of California, Berkeley, Revised by: C.-J. Lin, United Engineers and Constructors, Philadelphia, Pennsylvania, 1974., 1969,ASHSD2 evaluates the time dependent displacements and stresses of complex axisymmetric structures subjected to any arbitrary static or dynamic loading or base acceleration. The three-dimensional axisymmetric continuum is represented either as an axisymmetric thin shell, or as a solid of revolution, or as a combination of both. The axisymmetric shell is discretized as a series of frustrums of cones and the solid of revolution as triangular or quadrilateral toroids connected at their nodal point circles. The program can solve five cases of loading: dead load, arbitrary static load, arbitrary dynamic load, horizontal and vertical component of earthquake acceleration record applied at the base of the finite element model. A separate version of the program for static analysis only (ASHSAB.FOR) contains in-core as well as out-of-core equation solvers.
