TCL Command TASK PRECASTG

Description

The tendons are pre-tensioned and then the girder is cast. The preprocessor generates the necessary calculation tasks.

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 following other specific predefined arguments:

Key	Value	Dimension	Meaning
dh1	dh1val	DOUBLE	Duration in hours until the start of stressing
dh2	dh2val	DOUBLE	Duration in hours between start of stressing and start of pouring
dh3	dh3val	DOUBLE	Duration in hours between start of pouring and start of measurement (fcmtest)
castenv	cname	TEXT	Name of stressing bed
fcmtest	fcmval	STRESS	Test strength to determine the true concrete age
Dshrink	dshday	INT	Start of drying shrinkage
sgroup	sname	TEXT	The stress group is implicitly given by the tendons used and does not normally need to be specified. In special cases, a different stress group can be selected.

Definition of a typical phase for production. The girder is supported at 2 points and generated by PRECASTG. PRECASTG includes pre-stressing and concreting.
