D. TS500 Beam Design Brief dialog

The TS500 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).
Concrete

Set the strength either from the list of available grades, or by defining a cube strength, fck (in N/mm2).

Available concrete grades include: C20, C25, C30, C35, C40, C45 and C50

Specify the maximum size of aggregate to be used (in mm)

Forces

Select whether to design the forces within the width of the column (support) or only up-to the face of the column (support).

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. 

The Min gap defines the spacing (in mm) between the top 2 layers.

Available bar sizes include: 12, 16, 20, 25,32, 40 and 50

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. 

The Min gap defines the spacing (in mm) between the bottom 2 layers.

Available bar sizes include: 12, 16, 20, 25,32, 40 and 50

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: S220a, S420a or S500a

If the User fyk option is selected, specify a size. The bend radii can be specified in the Bending Dimensions dialog by clicking the Bending Dimensions… button.

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

Select the Epoxy Coated option if the development length calculations should consider this reduction.

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.
Note: Unless stated otherwise, the available bar sizes include: 6, 8, 10, 12, 16, 20, 25, 32, 40 and 50

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). 

Select 'Include Axial Load Effects' to account for the axial forces in design of longitudinal reinforcement

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 Select either a standard grade from the list or User fyks to specify the steel yield strength (in N/mm2). If the User fyks is option is selected, you may also specify custom minimum bending radii to be used with that strength in the Bending Dimensions dialog by clicking the Bending Dimensions… button.

The available steel grades include: S220a, S420a and S500a

Note: Unless stated otherwise, the available bar sizes include: 6, 8, 10, 12, 16, 20, 25, 32, 40 and 50
