The Criteria > Detailing Defaults command is used to define default reinforcement detailing parameters for concrete beams. Three separate tabs allow the user to enter defaults separately for gravity beams, gravity joists, and lateral beams. The parameters for each tab are essentially identical (see Chapter 5 for further explanation of how the values entered in this dialog box impact the final design).

• The top 3 input boxes allow the user to define the cutoff location of the top reinforcement relative to the clear span length.
• Splice Type - Used to define the splice type for top reinforcement. Options are Class A and Class B.
• End Stirrup Start Location, Interior Stirrup Start Location - Used to define the distance from the face of support to first transverse reinforcement. This is used to define the start and end of the transverse reinforcement segments. The shear and torsional check locations are still performed based on the applicable code sections.
• Minimum Number of Continuous Bars - Used to specify the minimum number of bottom and top bars that are continuous over the support.
• @ End Span - Used to define the cutoff location for the bottom reinforcement relative to the clear span length.
• @ Interior Span - Used to define the cutoff location for the bottom reinforcement relative to the clear span length.
• Bottom Bar End Condition - Used to specify the end condition for bottom bars at span ends. Options are Hooked and Straight.
• Stirrup Type - Used to specify default type of transverse reinforcement. Options are Open, Closed and Hoop.
• Stirrup Legs - Used to specify number of stirrup legs for transverse bar sets. The stirrup legs identify the number of bars that cross the beam shear failure cracks.

For the Joist detailing defaults, an additional option is included to design joists as beams and schedule them as joists. This option is useful in situations where wide module pans are used in the construction. In these cases often the engineer wants to place the beams in a joist schedule but the beams do not meet the joist design criteria in ACI 318 so they cannot be designed as joists.
