Vec (12)	Position of the more tensioned or less compressed fiber 1 Pure compression or pure tension 2 Top fiber 3 Bottom fiber

FCD

Design value of the concrete compression strength

FYD

Design strength of the reinforcing steel

TYP

Section type for the reinforcement minimum amount calculation

0	Beams (default value)
1	Columns
2	Slab
3	Wall (horizontal reinforcement)
4	Wall (vertical reinforcement)

Notes

- This command provides a simple tool to predesign and estimate the required reinforcement for section without defining elements, cross sections or materials of the model. This command may be used at any time and in any processor.

- This command predesigns a rectangular section defined by parameters and returns the total area of the lower and upper reinforcement; these values will be stored in a vector indicated by the user.

- The reinforcement amounts obtained are estimated values and do not depend on a selected building code. These values may not fulfill certain safety standards.  

- All these values must be supplied in user units.
