Why Dlubal Software?
Wind Load on Monopitch and Duopitch Roofs in GermanyIn Germany, DIN EN 1991-1-4 with the National Annex DIN EN 1991-1-4/NA regulates the wind loads. The standard applies to civil engineering works up to an altitude of 300 m.
Distribution Coefficient ζ in the Deformation Analysis of Reinforced Concrete ComponentsPerforming serviceability limit state design also includes taking into account the allowable deformation. The calculation of the deformation of reinforced concrete components depends on whether or not the observed cross-section is cracking under the applied loading. The governing control parameter in RF-CONCRETE Deflect is the distribution coefficient ζ.
Documenting Graphical Results of Reinforcement in RF-CONCRETE SurfacesRFEM offers different options to display results graphically which have been determined in RF-CONCRETE Surfaces. This article gives an overview of these options.
Considering End Releases Between SurfacesThis article deals with considering end releases between surfaces with line hinges and line releases. Examples are joints in reinforced concrete structures or frame joints in cross-laminated timber structures.
Determination of Bearing Resistance with "Drained" and "Undrained" Soil ConditionsThe 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.
Determination of Wind Loads for Canopy Roof Structures According to EN 1991-1-4If a canopy roof, for example a filling station roof, should be designed, a load determination having regard to Section 7.3 of EN 1991-1-4 is required. This article shows with an example the design of a slightly inclined troughed roof.
Consideration of P-Delta Effects (Second-Order Analysis) in the Response Spectrum Analysis According to ASCE 7-16RFEM offers the option to perform a response spectrum analysis according to ASCE 7-16. This standard describes the determination of seismic loads for the US-American market. It might happen that the so-called P-Delta effect has to be considered due to the stiffness of the entire structure to be able to calculate the internal forces and carry out the design.
Determination of Effective Lengths in RF-/CONCRETE ColumnsWith RF-/CONCRETE Columns, it is possible to determine effective lengths for columns automatically. This article describes which entries are necessary and how the calculation of the effective lengths is carried out.
Modeling and Bending Design of Point-Supported Flat SlabThis article describes how a flat slab is generated as 2D model in RFEM and the loading is applied according to Eurocode 1.
Snow Load on Monopitch and Duopitch RoofsIn Germany, DIN EN 1991-1-3 with the National Annex DIN EN 1991-1-3/NA regulates the snow loads. The standard applies to civil engineering works at an altitude of up to 1,500 m above sea level.
