Why Dlubal Software?
Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
Nonlinear Calculation of a Floor Slab Made of Steel Fiber Reinforced Concrete in the Serviceability Limit State with RFEM
Describing the procedure for the serviceability limit state design of a floor slab made of steel fiber reinforced concrete. This article shows how to perform the corresponding design for the SLS by means of the iteratively determined FEA results.
Nonlinear Calculation of a Floor Slab Made of Steel Fiber Reinforced Concrete in the Ultimate Limit State with RFEM
Steel fiber reinforced concrete is nowadays mainly used for industrial floors or hall floors, for foundation plates with low loads, basement walls and basement floors. Since the publication of the first guideline by the German Committee for Reinforced Concrete (DAfStb) about steel fiber reinforced concrete in 2010, the structural engineer can use standards for the design of the composite material steel fiber reinforced concrete, which makes the use of fiber reinforced concrete increasingly popular in construction. This article describes the nonlinear calculation of a foundation plate made of steel fiber reinforced concrete in the ultimate limit state with the FEA software RFEM.
With RF-FOUNDATION Pro, it is possible to determine settlements of single foundations and resulting spring stiffnesses of the nodal supports. These spring stiffnesses can be exported into the RFEM model and used for further analyses.
RFEM and RSTAB offer different options to model bored piles. One option is to display bored piles as single-valued supports or hinged columns. Another option is the realistic modeling while taking into account the soil by means of applying a member elastic foundation. The two following examples will describe it in detail. However, pile base resistance, skin friction and soil layers are not considered in this technical article.
The RF-/FOUNDATION Pro add‑on module designs single foundations (foundation plates, bucket and block foundations) for all support forces arising in the RFEM/RSTAB model. The geotechnical designs are performed according to EN 1997-1.
The product range of Dlubal Software contains various modules designing steel and timber connections. The RF-/JOINTS Steel - Column Base add-on module allows you to analyse footings of hinged or restrained steel column bases. For the cost-effective and safe design of the column base, the fastener selection, foundation geometry, and material quality are crucial.
A structural analysis does not only determine and design internal forces and deformations. It also ensures that the forces and moments in a structure are generated in a reliable way and applied to the foundation. Dlubal Software provides a wide range of products for structural analysis and design of steel and timber connections. The RF-/JOINTS Steel - Column Base add-on module allows you to design footings of hinged and restrained column bases. The design can be performed for both column base plates with or without stiffeners.
As of the program version x.06.1103, it is possible to enter a soil profile in RF‑/FOUNDATION Pro. This provides you the advantage to set several soil layers with different soil parameters above and under the foundation base. For entering the soil layers, there is a library with various soils that can also be extended with user‑defined soils. The user-defined soil profile is shown in an interactive information graphic. Any change, for example a soil thickness modification, is reflected in the graphic immediately.
In RF-/FOUNDATION Pro, there is the relevant reinforcement concept for each design of bucket reinforcement by default.
