greenSlab

Design ground supported slabs (slabs-on-ground) with steel or fiber reinforcement alone, or a combination with both steel and fiber reinforcement.

Verify the bearing capacity against uniform, line, and point/concentrated loads on all parts of the slab on both soil/ground and insulation.

greenSlab includes automatic thermal insulation and CO2 calculations and autogenerated documentation.

greenPad

Design pad/point foundations with steel or fiber reinforcement alone, or a combination with both steel and fiber reinforcement.

Ensure both sufficient concrete cross section and ground bearing capacity against vertical and horizontal loads, and fixed moments.

greenPad includes automatic optimization of the concrete volume as well as autogenerated documentation.

greenStrip

Design strip foundations (wall footings) with steel or fiber reinforcement alone, or a combination with both steel and fiber reinforcement.

Calculates the bearing capacity of the concrete cross section in both transverse and longitudinal direction.

greenStrip can also verify the bearing capacity of the strip foundation on both soil/ground and insulation with autogenerated the documentation.

greenSection

Design concrete cross sections (rectangular, circular or T-shaped) with steel or fiber reinforcement alone, or a combination with both steel and fiber reinforcement.

The bearing capacity is ensured in any and multiple combinations of section forces (moments, shear and normal forces).

greenSection investigates the bearing capacity in different limit states and autogenerates the documentation.

greenRetain

Coming soon!

Design retaining walls with steel or fiber reinforcement alone, or a combination with both steel and fiber reinforcement.

The bearing capacity is investigated for different limit states and conditions of Rankine ground pressure.

greenRetain will help optimize the shape and reinforcement of the retaining wall and will autogenerate the documentation.

greenBeam

Coming soon!

Design foundation beams, beams or wall lintels with steel or fiber reinforcement alone, or a combination with both steel and fiber reinforcement.

Depending on the static system, that is the support and loading conditions, the section forces are calculated and bearing capacity of the given concrete cross section is investigated.

greenBeam will help optimize the placement and use of reinforcement and will autogenerate the documentation.

greenPlate

Coming soon!

Design plates (self-bearing slabs) with steel or fiber reinforcement alone, or a combination with both steel and fiber reinforcement.

Depending on the static system, that is the support and loading conditions, the section forces are calculated and bearing capacity of the plate is investigated.

greenPlate will help optimize the placement and use of reinforcement and will autogenerate the documentation.

greenWall

Coming soon!

Design walls and basement walls with steel or fiber reinforcement alone, or a combination with both steel and fiber reinforcement.

The bearing capacity is investigated for different limit states and conditions of ground pressure and normal force.

greenWall will calculate the section forces, optimize the design, as well as autogenerate the documentation.

PPCD stands for Polypropylene Concrete Designs. This name was originally chosen when our main focus was on macro-synthetic polypropylene fiber reinforced concrete. However, we simply could not help ourselves trying to increase sustainability on a wider market. Therefore our focus has lately changed to optimization of concrete structures in general with both steel and fiber reinforcement. This means that we help minimize material consumption and reduce the amount of reinforcement while of course maintaining sufficient bearing capacity. Polypropylene fiber reinforcement is still a specialty of ours, and as such, our name remains.

Until recently, polypropylene fiber reinforcement and fiber reinforcement in general have been widely used as an addition to conventional steel reinforcement to reduce plastic shrinkage, i.e. not as structural reinforcement. Those times are changing. Using data from standardized tests, the material properties of polypropylene fiber reinforced concrete can now be used to design virtually any concrete structural element. However, the static system and the requirements of the concrete structure are important parameters when determining if the element can be reinforced with fiber reinforcement alone, or if it should be designed in combination with steel reinforcement. At usual dosages of macro-synthetic polypropylene fiber reinforcement the concrete cross section behaves with a tension softening mechanism, which means that in order to make designs with fiber reinforcement alone, the system has to be static indeterminate and/or have the possibility of plastic redistribution of the loads. Ground supported slabs (slabs-on-ground) and foundations are perfect examples of this.

Polypropylene fibers can indeed be used instead of steel fibers. Even with several advantages. Macro-synthetic polypropylene fiber reinforcement is in itself a more environmentally friendly solution compared to steel fiber reinforcement - see the DURUS EasyFinish environmental product declaration (EPD) here - but since polypropylene cannot corrode, the exposure class of the concrete can often be reduced, reducing the cement content and thus reducing the CO2-emission of the entire solution. Furthermore, there are some work environmental benefits such as easier pumping and no pointy ends. However, the residual flexural tensile stresses with steel fiber reinforced concrete (SFRC) are usually higher than those for macro-synthetic polypropylene fiber reinforced concrete (MSFRC).

Macro-synthetic polypropylene fiber reinforced concrete (MSFRC) can in many cases completely substitute conventional steel reinforcement but it is important to know that macro-synthetic polypropylene fiber reinforced concrete behaves with a tension softening mechanism at usual dosages. This means that in order to make designs with fiber reinforcement alone, the system has to be static indeterminate and/or have the possibility of plastic redistribution of the loads. Ground supported slabs (slabs-on-ground) and foundations are perfect examples of this. When these conditions are not met, fiber reinforcement can be used in combination with steel reinforcement to at least reduce the amount of steel required.

Using Finite Element Method (FEM), we can design just about anything but it is important to know that macro-synthetic polypropylene fiber reinforced concrete behaves with a tension softening mechanism at usual workable dosages. This means that in order to make designs with fiber reinforcement alone, the system has to be static indeterminate and/or have the possibility of plastic redistribution of the loads, such as ground supported slabs (slabs-on-ground) and foundations. For static determinate structures and when these conditions are not met, fiber reinforcement can be used in combination with steel reinforcement to reduce the amount of steel required.

Our software is developed to make the design of the specific listed concrete structures as easy and efficient as possible. If the concrete structure you look to design is not part of the listed element programs we can help you make the design. We usually use Finite Element Method (FEM) to calculate the section forces of the concrete structure depending on the support and load conditions after which we design the concrete structure using our own greenSection. If you know or can calculate the section forces of the strucutre, you can make the design with steel or fiber reinforcement alone, or a combination with both steel and fiber reinforcement using our greenSection.
