The Transversal reinforcement tab of the Definition of calculation parameters dialog box for NEN Code:
In the top part of a dialog box, data about parameters of reinforcing steel can be determined. It can be completed by giving fyk 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. A diameter list in metric units is accessible.
- Number of legs, that allows to define two, three, four and more legs of stirrups
- Inclination, that is 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.
- A choice of calculation method: standard (a standard truss method EC2 4.3.2.4.3) or strut inclinations (a truss method with diagonals with variable inclination angle EC2 4.3.2.4.4).
