Why Dlubal Software?
Wind Simulation & Wind Load Generation
With the individual program RWIND 2 , wind currents around simple or complex structures can be simulated using a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
As for the previous generations of Dlubal programs, an integrated interface with Autodesk Revit is now also available for RFEM 6 and RSTAB 9. This article provides some general information about the interface as well as the Dlubal-relevant structural objects and parameters in Revit.
This paper written by Mahyar Kazemian, Sajad Nikdel, Mehrnaz MohammadEsmaeili, Vahid Nik and Kamyab Zandi is related to an ongoing project for which a structural digital twin of the Kalix bridge in Sweden is being developed and implemented. The overarching goal of the current paper is to present a method for and study the results of quantifying structural loads resulting from extreme climate events based on future climate scenarios for the Kalix bridge.
Nodal releases are special objects in RFEM 6 that allow structural decoupling of objects connected to a node. The release is controlled by the release type conditions, which may also have nonlinear properties. This article will show the definition of nodal releases in a practical example.
Line releases are special objects in RFEM 6 that allow structural decoupling of objects connected to a line. They are mostly used to decouple two surfaces that are not rigidly connected or transferring only compressive forces at the common boundary line. By defining a line release, a new line is generated at the same place which transfers only the locked degrees of freedom. This article will show the definition of line releases in a practical example.
The Steel Joist Institute (SJI) previously developed Virtual Joist tables to estimate the section properties for Open Web Steel Joists. These Virtual Joist sections are characterized as equivalent wide-flange beams which closely approximate the joist chord area, effective moment of inertia, and weight. Virtual Joists are also available in the RFEM and RSTAB cross-section database.
In the RFEM 6 and RSTAB 9 programs, it is possible to group objects based on different criteria. Hence, objects that meet the defined criteria can be selected and edited at the same time. This is possible with the “Object Selection” tool, which is comparable to “Special Selection” in RFEM 5.
Plastic hinges are imperative for the Pushover Analysis (POA) as a nonlinear static method for the seismic analysis of structures. In RFEM 6, plastic hinges can be defined as member hinges. This article will show you how to define plastic hinges with bilinear properties.
Windbreak structures are special types of fabric structures which protect the environment from harmful chemical particles, abate wind erosion, and help to maintain valuable sources. RFEM and RWIND are used for wind-structure analysis as one-way fluid-structure interaction (FSI).
In this paper, a novel approach was developed to generate CFD models at the community-level by integrating building information modeling (BIM) and geographical information systems (GIS) to automate the generation of a high-resolution 3-D community model to be employed as an input for a digital wind tunnel using RWIND.
RFEM 6 offers you the Building Model add-on for defining a building by means of stories. It is an advantageous tool for modeling, given that the stories can be adjusted in many ways afterwards.
