close to parallel) local axis. The local x
component of force is not offset. If global or
projected load is selected, then the local Y
component of load is offset the f
4
distance; the
local Z component is offset the f
4
distance; and
the local X component is not offset.
-OR- [The following f
4
and
f

implemented]
f
4
= If f
14
is not blank, then f
4
is the perpendicular
local y distance from the member shear center to
the local z-plane of loading.
f
14
= Perpendicular local z distance from the member
shear center to the local y-plane of loading.
LIN specifies a linearly decreasing or increasing, or a
triangular load. If the load is linearly increasing
or decreasing then f
7
is the value at the start of
the member and f
8
is the value at the end. If the
load is triangular, then f
7
and f
8
are input as zero
and f
9
is the value of the load in the middle of the
member.
TRAP specifies a trapezoidal linearly varying load that
may act over the full or partial length of a
member and in a local, global or projected
direction. The starting load value is given by f
10
and the ending load value by f
11
. The loading
location is given by f
12
, the loading starting
point, and f
13
, the stopping point. Both are
measured from the start of the member. If f
12
and
f
13
are not given, the load is assumed to cover the
full member length.
X, Y, & Z in the direction-spec and local-spec specify the
direction of the load in the local (member) x, y and z-axes.
GX, GY, & GZ in the direction-spec specify the direction of the
load in the global X, Y, and Z-axes.
PX, PY and PZ may be used if the load is to be along the projected
length of the member in the corresponding global direction. Load
