The Transversal reinforcement tab from the Definition of calculation parameters dialog for ACI 318/95 code or ACI 318/95 metric code:
At the top of the dialog, parameters of reinforcing steel data are defined. These can be entered by either choosing the appropriate steel grade or entering fy resistance.
Either stirrups or spirals may be chosen for Transversal reinforcement. Presently, spiral reinforcement is not available.
At the bottom of the dialog, parameters of stirrup reinforcement are defined:
- Type of reinforcing bars for a stirrup. If (on the General tab) the Use the types according to ASTM option is selected, ASTM bars are accessible. Otherwise, a diameter list in metric units is accessible.
- Number of legs, that allows to define two, three, four and more legs of stirrups
- Inclination, so the angle between longitudinal and transversal reinforcement; a list of choice contains the following angle values: 90, 65,5 and 45 degrees
- Number of reinforcement zones, allowing you to specify the maximum number of zones to which stirrup spacings are assigned. For each zone a spacing of stirrups is uniform.
- Modularity of spacings, determining a list of stirrup spacings by modularity value. If a Modularity of spacings is defined as 2" , the accessible spacings are 2,4,6,8 etc., and for Modularity of spacings as 0,5", the accessible spacings are 0.5, 1, 1.5, 2.0...
- A list of user defined stirrup spacings not linked with any modular value for element reinforcement. For example 1 ,2 ,3 ,6 , and 9.
