prop_title
Area		Gapini

Field	Contents	SI Unit Example
prop_ID	Property identifier (Integer, maximum 10 digits)
unit_ID	Optional unit identifier (Integer, maximum 10 digits)
prop_title	Property title (Character, maximum 100 characters)
Area	Initial cross section (Real)
Gapini	Initial gap Default = 0 (Real)

1.	For truss elements, if the cross section variation is computed as:

where, is the Poisson’s ratio given in the material law.

2.	The truss is activated only if:

The current distance between truss nodes is smaller than the initial length minus Gapini.

3.	Gapini should be Gapini > 0. Negative Gapini will be treated as 0. The truss will not be activated in tensile.
