Inverted-tee beam (52)

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

  • Meshreinforcement that represents a mesh of steel bars in two perpendicular directions

    In Tekla Structures, the reinforcement mesh bars in one direction are called main bars and reinforcement mesh bars perpendicular to them are called crossing bars.

    for shear reinforcementreinforcement provided to resist shear force

    Shear reinforcement in beams is in form of stirrups and in columns in form of ties.

    in the beam stem

  • Stirrups for shear reinforcement in the beam stem

  • Reinforcement meshreinforcement that represents a mesh of steel bars in two perpendicular directions

    In Tekla Structures, the reinforcement mesh bars in one direction are called main bars and reinforcement mesh bars perpendicular to them are called crossing bars.

    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:

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.
