OBD/RM Bridge\Analyzer\Structure\Elements\Time


OBD/RM Bridge\Analyzer\Structure\Elements\Time allows the users to define the Elements parameters describing the behavior in time. The Element table includes parameters for governing the time behavior for:

  1. Status: Activation status of the element
    1. Inact: Element is not active (has not yet been activated or has been deactivated)
    2. Act: Element is active
  2. C&S: Creep and shrinkage:
    1. Age: Concrete age when the element is activated
      1. ts: Concrete age when the shrinkage process starts
      2. RH: Average relative air humidity of the environment of the element (in %)
      3. RPR: Stiffness ratio (As/Ac * Es/Ec)
    2. TMP: Average ambient air temperature on site  
  3. THA: Damping behavior in dynamic time history analyses:
    1. Alpha;Beta: Rayleigh-damping constants: [c] = alfa*[m] + beta*[k]
    2. 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 Recalc > Dynamics is taken if no element value is defined.
