TCL Command REMOVELAT

Description

The task is used when parts of the structure are removed. The affected elements are deactivated (DEACTIVATE) and the forces are transferred (LCTRANSFER). These two tasks are generated by the preprocessor from the task REMOVAL. The force transfer affects all relevant load sums that were specified in the construction plan. To de-activate a support in the sub-model (precast girder), its position are specified. The support is unknown to the main model.

Arguments

The basic arguments correspond to those of all tasks (cf. TCL Command TASK). The other arguments are to be entered in the form "key=value".

There are the following additional specific predefined arguments, cf. UI-input of REMOVAL:

Key	Value	Dimension	Meaning
refpt	pname	TEXT	Reference point that defines the position of the support in the cross-section of the girder
at	station	LSTATION	Longitudinal distance of the support from the start of the girder (station > 0) or from the end of the girder (station < 0)
lcsuffix	suffix	TEXT	Suffix of the load case name under which the transfer forces are stored
init	TRUE or FALSE	BOOLEAN	The results of the removed elements in the load sums are initialized or not.

Typical construction phase for lifting a precast girder. Two supports at top "P_top" at position are activated. Two supports at bottom "P_bott" are de-activated.
