The Reinforced Concrete Design Expert performs a consistent analysis of the concrete elements according to the selected standards. The available Reinforced Concrete standards are BAEL91 (France), STAS 10107 (Romania), ACI (United States of America) and Eurocodes 2 with several national appendixes:
The user can speed up the modeling using the "level" system property. In this case, the columns are created with one click and the walls with just two clicks.
ADVANCE Design offers complete libraries of concrete materials (i.e., ACI318-08, ACI318M-08, EN206, NFB, STAS 10107/0-90) and the possibility to define materials with custom properties.
The properties list of linear concrete elements includes all the required parameters for concrete cover, cracking, reinforcement, buckling length, etc. that are taken into account during the concrete calculation.
ADVANCE Design performs specific concrete design calculations, as a function of the element type. In the properties window you can specify if the corresponding element should be considered as a beam or column.
For columns, there is the option to define the buckling lengths calculation method and specify locally if the element has braced or unbraced nodes.
The properties list of planar concrete elements includes all the required parameters for concrete cover, cracking, reinforcement, etc. that are taken into account during the concrete calculation.
The reinforcement of planar elements can be defined for both directions. You can define fabrics and/or bars for a global distribution and for additional distributions on specific zones.
The calculation assumptions referring to the reinforced calculation method, the columns calculation method, buckling, calculation sequences, bars distribution, etc. can be globally defined through a single operation, for all reinforced concrete elements of the model.
The design assumptions can be modified at any time, in the modeling step and in the analysis step (when modifying the assumptions during the analysis step, it is necessary to rerun the reinforced concrete calculation).
The calculation assumptions referring to the reinforced concrete elements attributes can be defined for each element or selection of elements, using the corresponding element(s) properties list.
For a faster and more accurate definition of the reinforced concrete elements properties, you can define design templates that can be promptly applied on a selection of elements. Several design templates can be used in the same model. The design templates can be saved as XML files and imported in other projects, making the properties definition a time saving process.
The concrete design expert performs the reinforcement calculation of the concrete linear and planar elements by serviceability limit states (SLS) and ultimate limit states (ULS and AULS).
For linear elements, the design expert calculates the upper and lower longitudinal reinforcement of the cross section, which is subject to all possible types of action effects: tension and pure compression, simple or combined bending, oblique bending.
The calculations are performed according to the available reinforced concrete design standards, comprising all the positions of stress pivots and allowing the calculation of the compressed reinforcement. The transverse reinforcement resulting from the shear force and the longitudinal reinforcement resulting from the torsional forces are also calculated. The reinforcement of fragility condition or of minimum percentage is specified. For columns, the results must be processed by a stability criterion, in order to take into account the second order effects (buckling).
For planar elements, the design expert calculates the upper and lower longitudinal reinforcement along the local x and y directions of elements which are subject to all possible types of action effects: tension and pure compression (membrane forces Fx , Fy, Fxy), simple bending (plate moments Mx, My, Mxy) and combined bending (shell forces Fx, Fy, Fxy and moments Mx, My, Mxy).
The calculations are performed according to the available reinforced concrete design standards, comprising all the positions of stress pivots and allowing the calculation of the compressed reinforcement. For thick plates, it calculates the transverse reinforcement resulting from the shear forces Fxz and Fyz.
Once the verification is launched, the command line informs about each step of the process. If errors are found during the calculation, the verification messages are displayed on the command line along with the IDs of the elements to which the messages refer.
When the calculation process is completed, you have access to advanced result verification and a multitude of tools for customizing the display of the graphic results in the most relevant way.
The column analysis concerns the reinforcement dimensioning for each column and the combined bending verification of columns with interaction curves - a process that detects if the column's force component is inside the interaction area. The reinforcement dimensioning is made automatically, during the reinforced concrete calculation, based on the defined assumptions. The calculation engine offers the optimal solution for the reinforcement bars distribution and diameters.
After performing the reinforced concrete calculation, if the detailed beam calculation is enabled, you have access to ADVANCE Design results for the longitudinal and transverse reinforcement distribution for each beam.
The program offers the most suitable distribution solution. Based on this reinforcement distribution, the Cracked section inertia coefficient is calculated for each beam.
However, the user has the option to modify the values and launch a new calculation. The reinforcement area result is automatically displayed. The serviceability verifications (stress and cracking) are done according to the updated reinforcement values.
The reinforced concrete verification report provides a complete diagnosis of the model in different outputs: tables, texts, graphical post-processing. The report can be customized to suit your requirements.
Once the report content has been defined, there is no need to recreate the calculation report when the model undergoes any modification. The report contents, including post-processing views, are automatically updated at each calculation iteration (if specified) while preserving all the settings previously made:
