Revision of Gen2010

Section List

Select the sections for which their rebar data will be changed.

SECT : Section ID

Name : Section Name

Bar: Status of rebar placement

(In: rebars are placed, -: rebars are not placed)

Create Sub Section

Add or modify rebar data of a Sub-Section (ex. section ID-1, 2,3...).

Note 1

Sub Section is useful when a user needs to place a different rebar data to members which are defined as an identical section property.

Note 2

If the user deletes a rebar data of Sub-Section, the member will be changed to their initial rebar data. For example, if '411-1' sub-section rebar data is deleted, the rebar data of the corresponding members is changed to' 411' rebar data.

Element List

List of members which correspond to the selected rebar data.

Note.

When a number of elements are assigned to a single Member in Member Assignment, the smallest element number will be shown in the Element List field.

Section Definition

All section: Select when rebar data for i-end, middle and j-end are the same.

Both End & Center: Select when rebar data of i-end and j-end are the same.

Each End & Center: Select when rebar data of i-end, middle and j-end are the same.

Rebar Data

Main Rebar

Top: Enter the data of top rebar.

1: Enter the number and size of top Rebar in Layer 1.

2: Enter the number and size of top Rebar in Layer 2.

Bottom: Enter the data of bottom rebar.

1: Enter the number and size of the bottom rebar in Layer 1.

2: Enter the number and size of the bottom rebar in Layer 2.

Stirrup : Enter the rebar size, the number of legs and the spacing of stirrup bars

Note. When IS456:200 design code is selected

1. Under the IS456:2000 Concrete Design Code, only an even number of legs can be selected.

2. Limitations:

a. When a user assigned an odd number and changed the design code to IS456:2000, the design won’t be performed for the corresponding members.

b. When a user opens the Design Criteria for Rebar dialog after assigning an odd number with IS456:2000 design code, the value will changed to '2' automatically.

Skin : Enter the rebar size and the spacing of side bars

Note.

This row can be activated for torsional strength verification as per Taiwanese design code (TWN-USD92).

Concrete Face to Center of Rebar

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

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

Note
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), the default value specified by the design code are applied.

Detail Figure

Same Main Rebar Size at Top and Bottom: Check on when the top rebar size is identically placed to the bottom rebar size.

Same Main Rebar Size at I, M and J: Check on when the rebar size of i-end, middle and j-end are identically placed.

Operation

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