Internal Variables > Design variables

Internal variables calculated or temporarily assigned program internal values, which —under a predefined name (not case-sensitive)— can be used as arguments for for evaluating user defined variables.

Setting

Description

Modification button

Values of internal variables can be temporarily changed for evaluating the influence on related user defined variables. The evaluation of all dependent user defined variables is performed immediately after switching to the variables presentation pad.

Creep / Shrinkage / Relaxation:

Variables used in the design functions of the program (mainly for the reinforced concrete design)

Setting	Description
RES_N	Normal force in a certain element point
RES_M	Bending moment (My/Mz) in a certain element point
Ax	Cross sectional area of the element being considered
Es	Young Modulus of the reinforcement steel
AS	Total reinforcement area
fyd	Design value of the yield strength of the reinforcement steel
fcd	Design value of the concrete compression strength
CS_YZ	Width/depth of the cross section (for My/Mz)
CS_IYZ	Moment of inertia around the corresponding axis (Iy or Iz)
BUCK_L	Element buckling length for certain direction ( from LSet)
IMP_NY	Imperfection factor of element for certain direction ( from LSet)
FACT_YZ	Multiplication factor for pier dimensioning (Austrian Standard)
CS_D	Net cross-section depth in the considered direction (internal lever arm)
