Function
Enter the reinforcement details provided along the selected design strip for PT slab design check verification.
The design strip can be divided into up to three segments using start and end locations, allowing different reinforcement details to be assigned along the strip length.

Input
Selection
Story: Select the story containing the design strip.
Design Strip: Select the design strip for which reinforcement data will be provided
Design Strip Reinforcement View
Displays the selected design strip, design section locations, span length, and reinforcement distribution along the strip.
The reinforcement layout is divided into three regions along the span:
I-Part: Support region near the start of the span where negative moments may govern the reinforcement requirements.
M-Part: Mid-span region where positive moments generally govern the reinforcement requirements.
J-Part: Support region near the end of the span where negative moments may govern the reinforcement requirements.
Table
Span: Span number associated with the reinforcement data.
T/B: Indicates whether the reinforcement needs to be placed at the Top or Bottom face of the slab.
dc: Distance from the concrete face to the centre of reinforcement used for design calculations.
Method: Specifies the method used to define reinforcement within the selected region.
Number: Reinforcement is defined by specifying the number of bars to be provided.
Spacing: Reinforcement is defined by specifying the centre-to-centre spacing of bars.
Starting: Starting design section number defines the extent of the reinforcement region.
Ending: The ending design section number defines the extent of the reinforcement region.
No. of: Number of reinforcing bars provided when 'Number' is selected as the method.
Rebar: Reinforcing bar size assigned to the region.
Spacing: Centre-to-centre spacing of reinforcing bars when spacing is selected as the method.
Connect Model View
Synchronises the reinforcement display with the active model view.
