Summary: ANSR is a general purpose computer program for static and
dynamic analysis of nonlinear structures. In it, a structure is
idealized as an assemblage of discrete finite elements. Each node
may possess up to six degrees of freedom. The structure mass is assumed
to be lumped at the nodes. Viscous damping effects may be included, or
damping proportional to mass, specified. Static loads are applied in a
series of load increments, each load increment being specified as a
linear combination of static force patterns. This feature permits
nonproportional loads to be applied. Dynamic loading may consist of
earthquake ground accelerations, time-dependent nodal loads, or
prescribed initial values of nodal velocities and accelerations. The
elements available are:
[1] A three-dimensional truss element, which may yield in tension
and yield or buckle elastically in compression. Large displacement
effects may be included.
[2] A two-dimensional 4-to-8 node finite element for plane stress,
plane strain, and axisymmetric analysis. Large displacements may be
included and the material may be specified to be isotropic linearly
elastic, orthotropic linearly elastic, or isotropic elastic-perfectly
plastic with the Von Mises yield function. Nonlinearities are introduced
at the element level only and may be due to large displacements, large
strains, and/or nonlinear materials.
[3] INEL2, beam-column element which has two-dimensional stiffness and
yield characteristics, may be located arbitrarily in a three-dimensional
structure and is intended primarily for modeling beams.
[4] INEL3, a beam-column element which has three-dimensional stiffness
and yield characteristics, can be used for modeling columns in which
biaxial bending effects may be important and also for structures such
as elevator shafts. In INEL2 and INEL3, allowance has been made for
rigid floor diaphragms by means of a "slaving" feature incorporated
into the elements at the element level because ANSR-1 cannot account
for slaving at the nodal level. Both elements also allow for rigid end
zones and for initial element actions.
[5] The inelastic brace element, INEL4, is a simplified model to describe
the macrobehavior of a brace (i.e., the axial force-displacement
hysteretic rule). The axial force-displacement algorithm simulates the
observed behavior with nine piecewise linear zones. The orientations of
the zones are defined by: member properties, control displacements,
forces, and slopes. All of these properties are user-selected input to
the algorithm.
The code is organized to permit the addition of new finite elements to
the library with relative ease. The program permits the user considerable
flexibility in selecting a variety of solution schemes, including
step-by-step, iterative, and mixed schemes. For static analysis, a
different solution scheme may be employed for each load increment. The
dynamic response is computed by stepwise time integration using Newmark's
beta-gamma-delta operator.
