Bending Reinforcement with Schedule Actions: UltSup or UltLc.

A selection of elements for performing the ultimate capacity check can be done Structure > Elements > Checks.

The following requirements already exist for performing these schedule actions:

• The relevant internal force state (ultimate limit state);
• The required material properties (stress-strain diagrams);
• The reinforcement groups (properties groups / attributes sets);
• Any prescribed reinforcement amount can be defined in Structure > Elements > Checks;
• The required reinforcement amount can be performed with the option Rein;
• Definition of the prestressing tendons for prestressed structures.

Cracking Reinforcement with Schedule Actions: CrackSup or CrackLc.

These actions calculate the required additional reinforcement to meet the crack width design criteria.

A selection of elements for performing these actions can be done Structure > Elements > Checks.

Crack width design usually defined in individual national codes includes:

• Verification of minimum reinforcement area in the cross sections, A_min;
• Limitation of crack width for the structural elements under the relevant loading combination, A_load.

The reinforcement stress is calculated with presuming cracked conditions and nonlinear material behavior.

Longitudinal Reinforcement with Schedule Actions: UltSup, UltLc, CrackSup or CrackLc.

With respect to functionality, Longitudinal bars can be considered in bending and cracking calculations and after they can be used to compute the reinforcement layout.

For the reinforcement bars arrangement, RM Bridge has two types of solutions:

• Bars uniformly arranged along a specified line (straight, polygonal or curved);
• Bars arranged in specified points.

Reinforcement layout from view options, can be presented in the main window and results saved in in Excel spreadsheet file and in *.lst file.

Longitudinal Reinforcement can be saved in a 3D DGN file.
