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.
This article describes the different options for determining the allowable deformation of crane girders. Since multi-span beams and flexible lateral supports (curling bracing) are used in practice, clarity is to be created here about the selection of the correct method.
Comparing the Stability Analysis of a Column Containing Internal Forces from Load Combinations with an Enveloping Result Combination
This example will show what you should consider when you perform column design for bending and compression with regard to the internal forces from load combinations and result combinations.
For crane runways with large spans, the horizontal load from skewing is often relevant for the design. This article describes the origin of these forces and the correct input in CRANEWAY. The practical implementation and the theoretical background are discussed.
Influence lines have become less important nowadays due to the fast computer systems. However, it might be an advantage to use influence lines in the phase of preliminary design, but also in the actual creation of the structural designs. With the RF-INFLUENCE add-on module, it is possible to generate and evaluate influence lines and influence surfaces easily due to a fixed internal force. This technical article describes with a simple example the basics to determine and evaluate influence lines.
In practice, an engineer often faces the task of representing the support conditions as close to reality as possible in order to be able to analyze deformations and internal forces of the structure subjected to their influence and to enable as much cost‑efficient construction as possible. RFEM and RSTAB offer numerous options for defining nonlinear nodal supports. This second part describes the options for creating a nonlinear support for a restraint and provides a simple example. For better understanding, the result is always compared to a linearly defined support.
RFEM and RSTAB provide numerous variants of the nonlinear definitions of nodal supports. In the following, in continuation of an earlier article , the other possibilities of nonlinear support design for a displaceable support will be shown by a simple example. For better understanding, the result is always compared to a linearly defined support.
In practice, an engineer often faces the task of representing the support conditions as close to reality as possible in order to be able to analyse deformations and internal forces of the structure subjected to their influence and to enable as much cost‑efficient construction as possible. RFEM and RSTAB provide numerous options for defining nonlinear nodal supports. The first part of my article describes the options for creating a nonlinear free support and provides a simple example. For better understanding, the result is always compared to a linearly defined support.
BIM is often used when it comes to data management in civil engineering. The individual disciplines of architecture, structural design, construction, and structural monitoring are coming closer together. Building Information Modeling makes this possible.
Dlubal Software provides a wide range of formats for data exchange. The following article explains the details of the interface with Autodesk Revit and, particularly the export settings.
Building in existing structures has always been an area of expertise for engineers. Additional loads often have to be added to the existing buildings. In this case, steel girders with end plates and dowel connections are frequently used.
When you receive an RFEM or RSTAB file for further processing, the structures will be displayed in the program using the display settings of the last editor. If the settings do not correspond to your requirements, you can simply right‑click the empty area in Project Navigator - Display and select ‘Dlubal Standard’. This returns the settings to the default values.
