Elem-From/Elem-To/Elem-Step
|
Elements, whose time parameters shall be modified. |
|
Age
|
Concrete age when the element is activated |
|
ts
|
Concrete age when the shrinkage process starts |
|
RH
|
Average relative air humidity of the environment of the element (in %) |
|
RPR
|
Stiffness ratio (As/Ac * Es/Ec)
- As: Reinforcement area
- Ac : Concrete area
- Es: E-modulus of reinforcement
- Ec: E-modulus of concrete
|
|
TMP
|
Average ambient air temperature on site |
|
Alpha, Beta
|
Rayleigh coefficients for calculating damping matrices in dynamic time history analyses. | Setting | Description |
|---|
| Global |
Values for all elements identical and defined in the Recalc pad. |
| Local |
Element-specific damping values are defined. The coefficients can be directly input by the user or recalculated by the program from 2 damping constants (logarithmic decrement) valid for 2 characteristic frequencies. (Input in the pad displayed when selecting the arrow to the right of the input field) Note: Alpha and Beta belong together. Both values must be defined in the same manner, i.e. either both are taken over from the global settings, or both are directly defined, or both are recalculated from the same set of damping constants and characteristic frequencies.

|
Damping
|
Modal damping ratio for assessment of the different natural modes in case of modal analysis with frequency-dependent damping. The global value Xsi defined in is taken if no element value is defined. |
