RF-CONCRETE 4.xx

Reinforced Concrete Design for Members and Surfaces (Plates, Walls, Planar Structures, Shells)

The add-on module RF-CONCRETE is used for the design of structural components made of reinforced concrete. It consists of two parts:

RF-CONCRETE Surfaces designs plates, walls, planar structures and shells for the ultimate and the serviceability limit state.
RF-CONCRETE Members is used for the reinforced concrete design of member elements.

RF-CONCRETE performs the reinforced concrete design of surfaces, members and sets of members for the ultimate and the serviceability limit state according to the following standards:
DIN 1045-1:2008-08
DIN 1045-1:2001-07
DIN 1045:1988-07
DIN V ENV 1992-1-1:1992
EN 1992-1-1:2004 + AC:2010 (optionally available)
SIA 262:2003 (optionally available)
ACI 318-11 (optionally available)
ÖNORM B 4700:2001-06 (optionally available)

Features

Automatic import of internal forces from RFEM
Ultimate limit state and serviceability limit state design

In addition to the NADs listed above, you can define application documents by yourself, applying user-defined limit values and parameters.

Flexibility due to detailed setting options for basis and extent of calculations
Quick and clear results output to overview results distribution immediately subsequent to the design
Graphical results output integrated in RFEM, for example required reinforcement
Clearly-arranged numerical results output displayed in tables and option to represent results graphically in the structure
Complete integration of data output in RFEM printout report


Features of RF-CONCRETE Surfaces Free definition of reinforcement layers (2 or 3 layers) in the ultimate limit state Due to a vectorial representation of the internal forces' main stress directions it is possible to adjust the orientation of the third reinforcement layer to the actions in an optimal way. Design variety to avoid compression or shear reinforcement Design of surfaces as deep beam (theory of membranes) Option to define basic reinforcements for top and bottom reinforcement layer Definition of provided reinforcement for serviceability limit state design Results output in grid points of any selected grid The add-on module RF-CONCRETE can optionally be extended by a non-linear deformation analysis. The calculation is performed by an iterative process where the stiffness reduction in cracked sections (state II) is taken into account. For more information, see the product description for RF-CONCRETE NL. Design with design moments at column edges Itemization of reasons for failed design Design details for all design locations for better traceability of reinforcement determination The isolines for the longitudinal reinforcement can be exported as DXF file and reused in CAD programs where they provide the basis for reinforcement drawings.


Features of RF-CONCRETE Members Determination of longitudinal, shear and torsional reinforcement Representation of minimum and compression reinforcement Determination of neutral axis depth, concrete and steel strains Design of member cross-sections affected by bending on two axes Design of tapered members Determination of deformation in cracked sections (state II), for example according to EN 1992-1-1, 7.4.3 Consideration of creep and shrinkage Itemization of reasons for failed design Design details for all design locations for better traceability of reinforcement determination Options to optimize cross-sections Visualization of concrete cross-section with reinforcement in 3D rendering Output of complete steel schedule Fire protection design according to the simplified method (zone method) in accordance with EN 1992-1-2 for rectangular and circular cross-sections


Input To facilitate the data input, the surfaces, members, sets of members, materials, surface thicknesses and cross-sections defined in RFEM are already preset. Almost anywhere, the program provides the [Pick] function for selecting the elements graphically. In addition, you have access to the global material and cross-section libraries. Load cases, load groups and load combinations can be combined in various design cases to meet specific needs. Finally, you enter all geometric and standard-specific reinforcement settings for the reinforced concrete design in a table including several tabs. The geometric input is different in both RF-CONCRETE modules. In RF-CONCRETE Surfaces, for example, you must specify the concrete cover, the reinforcement direction, the minimum and maximum reinforcement, the basic reinforcement to be applied or the longitudinal reinforcement provided as well as the rebar diameter. In RF-CONCRETE Members, you must define specifications, for example, for the curtailment of rebars, the number of layers, the cut of links and the type of anchorage. When you perform the fire protection design for reinforced concrete members, you have to define the fire resistance class, the fire-specific material properties as well as the cross-section sides exposed to fire. Surfaces or members can be summarized in special "reinforcement groups", each defined by different design parameters. In this way, it is possible for example to calculate alternative designs quickly using different boundary conditions or modified cross-sections.


Results Subsequent to the design, RF-CONCRETE lists the required reinforcement and the results of the serviceability limit state design in clearly arranged tables. Moreover, the module displays all intermediate values. The results of RF-CONCRETE Surfaces are shown graphically as isolines, isosurfaces or numerical values. The results in the display for the longitudinal reinforcement can be sorted by required reinforcement, required additional reinforcement, provided basic or additional reinforcement as well as provided total reinforcement. The isolines for the longitudinal reinforcement can be exported as DXF file and reused in CAD programs where they form the basis for reinforcement drawings. The results of RF-CONCRETE Members can be displayed as result diagrams on the respective member. The reinforcement concepts for the longitudinal and the link reinforcement including sketches are documented appropriately. It is possible to edit the reinforcement proposal and to adjust for example the number of members and the anchorage. The modifications will be updated automatically. The concrete cross-section including reinforcement can be represented and visualized by 3D rendering. Take advantage of this option to document the reinforcement data in an optimal way for creating reinforcement drawings including steel schedule.
