Design Criteria for Rebars

Enter the standard sizes of rebars used in the design of reinforcement for slab/wall elements.

From the Main Menu select  Design > Design > Meshed Slab/Wall Design > Design Criteria of Rebar.

Basic Rebar for slab

Enter basic rebar data for slab:

Top-Dir.1:Enter rebar size and spacing for top slab in Dir.1

Bot-Dir.1:Enter rebar size and spacing for bottom slab in Dir.1

Top-Dir.2:Enter rebar size and spacing for top  slab in Dir.2

Bot-Dir.2:Enter rebar size and spacing for bottom  slab in Dir.2

Note: The basic rebar data as seen in the above dialog box is applied to all the slabs. If the user wants to apply different basic rebar data to different slabs, that can be done through Define Sub-Domain

For Slab Design

Enter the additional standard rebar sizes, the spacing of rebars and covers used in the slab design.

Rebar: Standard rebar sizes used for the slab design

Spacing: Spacing of rebars used for the slab design

Concrete Face to Center of Rebar (dT, dB)

Dir. 1: Cover thickness of Angle 1 Rebar

Dir. 2: Cover thickness of Angle 2 Rebar

For Mat Design

Enter the standard rebar sizes, the spacing of rebars and covers used in the foundation mat design.

Rebar : Standard rebar sizes used for the foundation mat design

Spacing : Spacing of rebars used for the foundation mat design

Concrete Face to Center of Rebar (dT, dB)

Dir. 1: Cover thickness of Angle 1 Rebar

Dir. 2: Cover thickness of Angle 2 Rebars

For  Wall Design

Enter the standard sizes of vertical and horizontal rebars and the placement layout of vertical rebars for wall members.

Vertical Rebar: Standard sizes for vertical rebars used in wall design

Horizontal Rebar: Standard size for horizontal rebars used in wall design

Spacing: Spacings of rebars used for the wall design

Concrete Face to Center of Rebar (dw)

Distance between the center of the end vertical rebars and the end of the shear wall (cover thickness).

Note

Spacing of rebars can be specified or deleted using .

For Shell Design

Enter the standard rebar sizes, the spacing of rebars and covers used in the shell design.

Rebar : Standard rebar sizes used for the shell design

Spacing : Spacing of rebars used for the shell design

Concrete Face to Center of Rebar (dT, dB)

Dir. 1: Cover thickness of Angle 1 Rebar

Dir. 2: Cover thickness of Angle 2 Rebars

Note

Layer thickness for the sandwich model can be defined using .

Consider Iteration for Optimal design  :

If you Check off the option, default height of Sandwich thickness is defined as the thickness of 20% of shell.

If you Check on the option, the optimum sandwich thickness will be automatically calculated and used in the analysis.

(When the option is checked on without calculation of the optimized thickness, the input limit thickness is applied.)

Number of Iteration: Enter the maximum number of iterations.

Convergence Tolerance: Enter the Convergence Tolerance value.
