Modify Beam Section Data

Enter the section dimensions and rebar data for RC beam members for strength verification.

From the Main Menu select Design > Concrete Design Parameter > Modify Beam Section Data.

From the Menu tab of the Tree Menu select Design > Concrete Design Parameter > Modify Beam Section Data.

First, select the members in the model and enter the following data:

Option

Select Add/Replace or Delete.

Add/Replace: Add the newly entered values or update the previously entered values.

Delete: Delete the entered values. Data entry is not required when deleting.

 

Section

Select the sections for which strengths will be checked.

ID : Section Number

SEL: Check on to select the members for which section changes are made and rechecked and the results are produced.

Note: Use SpaceBar Key to select or cancel.

Name : Section Name

Bar: Status of rebar placement (In: rebars are placed, -: rebars are not placed)

: Select all section data

: Unselect all section data

Click  : to modify the sectional shape and dimensions. Display the Section for Design dialog box (refer to "Section for Design").

 

 

Section Data (refer to Note 1)

Display the section data for beam members.

Shape: Sectional shape of the members

Hc: Height of the section

Bc: Width of the section

bf: Width of the T-section's flange

hf: Thickness of the T-section's flange

 

 

Rebar Data

Enter the reinforcing data at each position of the beam section for strength verification.

: Enter/modify rebar data at node i of the beam members. The following Definition of Beam Rebar dialog box is displayed:

Definition of Beam Rebar Dialog Box

Top Rebar
Enter the top rebar data.

One Layer: Rebar placement in one layer

Two Layers: Rebar placement in two layers

 : Number of top rebars in the upper layer

 : Number of top rebars in the lower layer

 : Rebar size

 

Bottom Rebar

Enter the bottom rebar data.

One Layer: Rebar placement in one layer

Two Layers: Rebar placement in two layers

 : Number of bottom rebars in the upper layer

 : Number of bottom rebars in the lower layer

 : Rebar size

 

Stirrup Bar Space: Spacing of stirrup bars

 

 : Enter the values or the selection and close the dialog box.

 : Do not enter the values or the selection and close the dialog box.

 

: Enter the reinforcing data pertaining to (1/4)L, (1/2)L and (3/4)L positions of the beam members. Data entry is identical to that for i-Node.

: Enter/Modify the reinforcing data at node j of the beam members. Data entry is identical to that for i-Node.

Stirrup Bar : Spacing of stirrup bars

Arrangement: Number of shear reinforcement legs

dT : Distance between the center of the top main rebars in the upper layer and the top surface of the section (cover thickness) (refer to Note 3)

dB : Distance between the center of the bottom main rebars in the lower layer and the bottom surface of the section (cover thickness) (refer to Note 3)

 

 : Enter the values for the selected members.

 : Close the entry Dialog Bar.

 

Note 1
The dimensions entered for the analysis model determine the height (Hc) and width (Bc) of the rectangular section (Shape = Rectangle). In such a case, the sectional shape of the beam members defined in the analysis model must be rectangular. The sectional values (Hc, Bc, bf, hf) entered in the analysis model are applied to T-sections (Shape = Tee). In such a case, the sectional shape of the beam members entered in the analysis model must be a T-shape. Use "Section for Design" to modify the sectional shape or the dimensions (refer to "Section for Design").

Call

From the Main Menu select Design > Section for Design

 

Note 2
The rebar data dialog box for a "Tee"-section is as follows:

Definition of Beam Rebar Dialog Box

Note 3
Enter the cover dimensions of the main rebars placed in the outer layers of the beam members. When the covers are not specified, (dT = 0, dB = 0), strength verification will not proceed.

 

Note 4
Rebar data at only one section among the locations of i-Node, Middle and j-Node may be entered. If there are no rebar data, the strength will not be verified.

When rebar data are entered for only one of the i-Node, j-Node and Middle locations: The rebar data will be applied to all the locations for strength verification.

When rebar data are entered for i-Node and j-Node: The i-Node rebar data will be used for the Middle for strength verification.

When rebar data are entered for i-Node and Middle: The i-Node rebar data will be used for j-Node for strength verification.

When rebar data are entered for Middle and j-Node: The j-Node rebar data will be used for i-Node for strength verification.

 

Note 5
When the rebar data are repeatedly entered for the same section, the values will be updated to the last values entered.

 

Note 6
The entered rebar data can be reviewed in the Data Table arranged in the order of section numbers. The user may Modify/Add and Delete items in the data table.

Access the data table following the procedure below.

From the Main Menu select Design > Concrete Design Parameter > Concrete Design Tables > Modify Beam Section Data.

From the Tables tab of the Tree Menu select Design Tables > Concrete Design Table > Modify Beam Section Data.
