Inverted-tee beam (52)

Creates typical flexural, shear, and ledge reinforcement for an inverted-tee beam.

Reinforcement created

Prestress straight or depressed strands for flexural reinforcement in the inverted tee stem
Mild longitudinal bars for flexural reinforcement
Mesh for shear reinforcement in the beam stem
Stirrups for shear reinforcement in the beam stem
Reinforcement mesh in the inverted-tee ledges
Stirrups for shear reinforcement in the inverted-tee ledges
Mild reinforcement in the top of the beam that will be used later to create a composite member
Mild reinforcement in the ends of the beam

Use for

Situation
Straight and depressed prestress strands
Varying strand pattern and strand number
To define longitudinal reinforcement in the stem
When you want reinforcement mesh in the stem
When you want stirrups in the beam stem
To use reinforcement mesh in the beam ledges
To use stirrups in the beam ledges
To define reinforcement for composite members
To add mild reinforcement to the beam ends

Before you start

Create the concrete inverted-tee beam.
Calculate the required area and quantity of strands and other reinforcement.
Define other reinforcement properties, such as debonding and pull values.

Defining properties

Use the following tabs in the Inverted-tee beam automated reinforcement layout (52) dialog box to define the properties of the objects that this component creates:

Tab	Contents	See also
Strand template	The allowable grid points for strands within the beam cross section.	Strand template
Strand pattern	The actual strand definitions.	Strand pattern
Strand profile	The vertical profile for strands in the beam.	Strand profile
Longitudinal rebar	Definitions for additional mild steel reinforcement in the beam. Reinforcement may be defined with a variety of parametric forms.	Reinforcing bar and bar group properties
Stem mesh	Definition for the mesh to be used in the beam stem. Mesh can run the full length of the beam, or be placed in short sections at either end of the beam. Mesh size, spacing, clearances, and length are all entered here.	Reinforcing bar and bar group properties
Stem stirrups	Definitions for the bent bar reinforcement in the beam stem, including stirrup shape, bar size, end clearance, number of bars, and bar spacing in five zones along the length of the beam.	Stem stirrups
Ledge mesh	Definition for the mesh to be used to reinforce the beam ledges. Mesh runs the full length of the beam. Mesh size, spacing, and clearances are all entered here.	Reinforcing bar and bar group properties
Ledge rebar	Definitions for the bent bar reinforcement in the beam ledges, including stirrup shape, bar size, end clearance, number of bars, and bar spacing in five zones along the length of the beam.	Ledge rebar
Composite	Definitions for the bent bar reinforcement added to the top of the beam stem for subsequent creation of composite elements. Bar size, embedment, projection, cover, end clearance, number of bars, and bar spacing in three zones along the length of the beam are all defined here.	Reinforcing bar and bar group properties
End rebar	Definitions for the bent bar reinforcement in the beam ends, including position, orientation, bar size and length, cover, and end clearance. Up to 6 horizontal and 6 vertical bars may be defined.	Reinforcing bar and bar group properties
Attributes	Name, class, and numbering properties of the strands, stirrups, and mesh bars.	Reinforcing bar and bar group properties
