Analysis
of 3-D Assemblies:
HYST
and PANEL form the foundation for a static/dynamic
three-dimensional structural model, PANEL-3D. This
program may be used to study any spatial
arrangement of shear walls, providing output which
includes distribution of foundation forces and
torsional deformations.
The
figure above shows a three-dimensional structure
consisting of a flat roof diaphragm and vertical
shear walls. One of the walls may be missing,
creating an opening. The loading, as
shown, is a lateral force and vertical loads
on the roof.
The
figure above, to the left (click to enlarge), shows
calculated push-over response for the structure
with or without an opening. The figure to the right
(click to enlarge) is the calculated response to a
cyclic lateral load.
