D. AIJ Beam Brief dialog

The AIJ Beam Design Brief has the following tabs for setting out the design parameters:

General tab

SettingDescription
Minimum cover Set the cover to the top, bottom and sides of the beams (in mm).
Aggregate Size Specify the maximum size of aggregate to be used (in mm)
Concrete Specify the concrete strength, Fc (in Kg/cm2).

Select whether this is a lightweight concrete mix.

Loading Type Select whether the loading is Short Term or Long Term.
Envelope The beams will be designed to the forces from the envelope selected from the pull-down list. Load Envelopes are added using the Define Envelope dialog.
Divide Beam Set the minimum number of segments that each member should be divided into for calculating the reinforcement

Main Reinforcement tab

SettingDescription
Top Bar Criteria Set the Minimum and Maximum allowable bar sizes to be used on the top of the beams.The link hanger size is used for detailing where no reinforcement bars are required for bending, but bars are required for supporting links.
Bottom Bar Criteria. Set the Minimum and Maximum allowable bar sizes to be used on the bottom of the beams.The link hanger size is used for detailing where no reinforcement bars are required for bending, but bars are required for supporting links.
Main Bar Type. Either select a standard grade from the pull-down list or enter the steel yield strength into the user value and set the bending dimensions to be used with that strength.

The available steel grades include: SR235, SRR235, SR295, SRR295, SDR235, SD295A, SD295B, SDR295, SDR345, SD345 and SD390

Specify whether the bars are epoxy coated.

Select whether the 'Development Length' is taken from the ACI 318 code, clause 12.2.2 or 12.2.3

Side Bar Criteria. Set either the minimum bar size to be used or let the program calculate which bars can be used to achieve a suitable spacing on deep beams.

Bar sizes include: 6, 8, 10, 12, 16, 20, 25, 32, 40 and 50

Note: Unless stated otherwise the available bar sizes include: 8,10,13,16,19,22,25,29,32,35,38,41

Shear Reinforcement tab

SettingDescription
Design Shear For Select whether or not to include for the shear forces within the width of the column (or support) by selecting either 'center Line of Support' or 'Column face' (support) or at a distance 'd' from the face of the column (support).
Shear Bar Criteria. Select the minimum bar size and number of legs (2, 3, 4, 5,or 6) to be used and set the minimum spacing (in mm).If the design requires a smaller spacing, then the number of legs will be increased.
Shear Bar Type. Either select a standard grade from the pull-down list or enter the steel yield strength into the user value (in N/mm2) and set the bending dimensions to be used with that strength.

The available steel grades include: SR235, SRR235, SR295, SRR295, SDR235, SD295A, SD295B, SDR295, SDR345, SD345 and SD390

Specify whether the links are 'Open' or 'Closed' for the classifying in the schedule.

Note: Unless stated otherwise the available bar sizes include: 8,10,13,16,19,22,25,29,32,35,38,41
