Reinforcement of concrete plates, shells and Slab-on-grade foundation design

Surface reinforcement can be calculated based on Eurocode 2. The calculation of the reinforcement of membrane, plate, and shell elements is based on the 3rd stress condition. Reinforcement directions are the same as the local x and y directions. The nominal moment and corresponding axial strengths are determined based on the restricted direction optimal design.

Available for:

Eurocode 2 EN 1992-1-1:2004
DIN DIN 1045-1:2001-07
SIA SIA 262:2003

In the surface reinforcement design, the following parameters must be assigned to the finite elements:

Materials, Reinforcement, Cracking,

Actual Reinforcement

Lets you apply an actual reinforcement to the surface elements depending on the calculated reinforcements. Using the actual reinforcement you can perform a non-linear plate deflection analysis.

Crack Opening Calculation

Reinforcement of concrete plates, shells and Slab-on-grade foundation design

After the assignment of the actual reinforcement the program calculates the crack openings and crack directions in the membrane, plate and shell elements.

The direction of the reinforcement is relative to the surface element’s local x and y axes.

The program displays the crack openings in a color coded mode, can draw the crack map and the crack angles.

Non-linear deflection of RC plates

In case of the linear static analysis the plate deflection is calculated according to the elastic theory. In fact the behaviour of RC plates is non-linear due to two opposite effects. The actual reinforcement increases the bending strength but cracking decreases it.

The non-linear RC plate deflection analysis follows up these two effects with the actual reinforcement.

The program performs a non-linear analysis in an iterative way using the moment-curvature diagrams of RC cross-sections. The strength effect of the tensile concrete is also taken into account. This non-linear analysis is available based on Eurocode, DIN 1045-1 (German), SIA-262 (Swiss), NEN (Dutch), MSz (Hungarian) and STAS (Romanian) design codes.

Punching analysis of column-plate connections

Punching shear control perimeters are determined based on the column cross-section and the effective plate thickness. Plate edges and holes are taken into account if they are closer to the column than six times the effective plate thickness. If column cross-section is concave a convex section is used instead.

Punching analysis can be performed based on the following design codes:

Eurocode 2 EN 1992-1-1:2004
DIN DIN 1045-1:2001-07

Reinforced concrete column and beam design

Column Reinforcement

On Reinforcement bars tab the cross-section can be choosen, material parameters of the concrete column and the rebars, buckling lengths of the column can be set and rebars can be placed. After clicking the Column Check tab N-M strength interaction diagrams are calculated.

Available for:

Eurocode 2 EN 1992-1-1:2004
DIN DIN 1045-1:2001-07
SIA SIA 262:2003

Beam reinforcement design

The beam reinforcement design module can be applied to beam structural elements modeled by beam or rib finite elements, that have the same material and constant or variable rectangular or T cross sections, assuming that the load is applied in the symmetry plane of the cross section. The computed longitudinal top and bottom reinforcement are of the same steel grade, while the stirrups could have steel grade different from the longitudinal ones.

Available for:

Eurocode 2 EN 1992-1-1:2004
DIN DIN 1045-1:2001-07
SIA SIA 262:2003

Pad & Strip footing design

Pad footing design

AxisVM can determine the necessary size and reinforcement of rectangular pad foundations (with or without pedestal), and can check the footing against sliding and punching according to Eurocode7 and MSz.

It determines the settlement of the foundation as well.

Available for:

Eurocode 7 EN 1997-1-1:2004

The size of the foundation can be entered or let AxisVM calculate it. If AxisVM calculates the size a maximum value must be specified. Using the soil profile and the internal forces this module determines the necessary size of the founda-tion in an iterative process. Then it calculates the effective area of the foundation for load cases and combinations, the design forces, moments and resistances, determines the settlement (for load cases and Service Limit State [SLS] combinations), efficiencies and the shear reinforcement if necessary. The module also checks the stability of the footing. Step sides must not be bigger than the respective side of the foundation.

Strip footing design

AxisVM can determine the necessary size and reinforcement of strip founda-tions (with or without pedestal), and can check the footing against sliding and punching according to Eurocode7 and MSz. It determines the settlement of the foundation as well. Strip footing design is similar to the pad footing design. Parameters describing the geometry of the strip section must be entered.

Available for:

Eurocode 7 EN 1997-1-1:2004

Cobiax Plate Elements design

If the AxisVM configuration includes the COBIAX (CBX) module, it is possible to place void formers into slabs achieving weight reduction (and concrete reduction) and making larger spans available.

Available for:

Eurocode 2 EN 1992-1-1:2004
DIN DIN 1045-1:2001-07
SIA SIA 262:2003

COBIAX design must take into account that void formers reduce the stiffness and shear resistance of the slab. The effect of smaller bending stiffness can be seen in the results. Where shear forces would exceed the reduced shear resistance, placing of void formers must be avoided. If the user defined the surface reinforcement parameters AxisVM calculates the design results used in reinforcement design. One of these design components is the difference between the actual shear force and the shear resistance.

If actual reinforcement is also defined AxisVM calculates with the ac-tual reinforcement.
