Why Dlubal Software?
Modeling Joints as Surface ModelWith RF-/FRAME-JOINT Pro, it is possible to design frame joints according to DIN 18800 or Eurocode 3. When considering non-standardized joints or taking a closer look at the joint and its behavior, it is recommended to use a modeling as surface model. The following article will show how such a model is created in principle.
Influence of Slip of Standardized Joints in Steel StructuresThis article deals with the stiffness of standardized joints according to the DSTV (German Steel Construction Association)/DASt (German Committee for Structural Steelwork) standards, often used in steel construction, and its effects on structural analysis and design results according to DIN EN 1993-1-1.
Fin Plate Connections: Theory and ApplicationFin plate connections are a popular form of pinned steel connections and are commonly used for secondary beams in steel structures. They can be easily used in beam structures arranged on the top edge, e.g. working platforms. Manufacturing expenditures in the workshop as well as the assembly costs on-site are normally manageable. The design seems to be completed easily and quickly, but has to be put into perspective to a certain extent in the following. Moreover, this connection type is basically possible as pinned beam to beam or pinned beam to column connection, whereas the first case is the more common one in design practice.
Modelling and Design of Pinned End Plate ConnectionRFEM offers the following possibilities to design a pinned end plate connection. Firstly, there is the possibility in RF-JOINTS Steel - Pinned to enter the corresponding parameters quickly and easily to receive a documented analysis including graphics. It is also possible to model such a connection individually in RFEM and then to evaluate or manually design the results. In the following example, the particularities of this modelling will be explained and the shear forces of the bolts will be compared to the corresponding results from RF-JOINTS Steel - Pinned.
Forces by Screw in Main-Connected Beam Joint
RF-/JOINTS Timber - Timber to Timber allows you to design main-connected beam joints. This article explains the determination of forces in screws of a beam connected to a torsionally rigid main beam.
Modeling Prestressed Bolt Connection
When modeling surface models, such as a frame joint or similar structures, there is always the question of how to model a prestressed bolt connection. In this case, it is always necessary to find a compromise between the practicable and detailed solution. The following article describes the modeling procedure of such a connection based on the joint diagram calculation method.
Calculation Example of Rigid End Plate Connection According to EN 1993-1-8
In this example, design resistance of an end plate according to EN 1993-1-8  is to be determined; the other components are not described here. To check the results, the dimensions of the connection IH 3.1 B 30 24 of Typified Connections  were used. The material S 235 and bolts with the strength 10.9 are used.
Analysis of Load-Bearing Capacity of Bolted Frame Joints According to EC 3-1-8
When designing bending-resistant connections from I-beams, the connection is dissolved into the individual parts. For these basic components of a joint, there are separate formula calculators for load-bearing capacity and stiffness. In RFEM and RSTAB, it is possible to design frame joints using the RF-/FRAME-JOINT Pro add-on module.
Columns Subjected to Tensile Stress in RF-/JOINTS Steel - Column Base
The product range of Dlubal Software contains various modules for design of 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.
