3.1.5.36. Multiplier Material Wrapper

This command is used to construct a Multiplier uniaxial material wrapper. The wrapper multiplies the stress and tangent of its wrapped UniaxialMaterial by a factor. Typical uses include overstrength factors for materials and p-y multipliers for shadowing effects in pile groups.

uniaxialMaterial Multiplier $matTag $otherTag $multiplier

Argument	Type	Description
$matTag	integer	unique material tag
$otherTag	integer	tag of a previously-defined UniaxialMaterial
$multiplier	float	factor applied to stress and tangent of the wrapped material

Example

1. Tcl Code

uniaxialMaterial Elastic 1 100.0
uniaxialMaterial Multiplier 2 1 0.8

2. Python Code

ops.uniaxialMaterial('Elastic', 1, 100.0)
ops.uniaxialMaterial('Multiplier', 2, 1, 0.8)
