The network-capable Project Manager controls the projects of all Dlubal Software applications in one central location. The projects are linked to the folders on the hard disk.
In this article, you will learn how to model and design cable structures in RFEM 6 or RSTAB 9.
This article describes and explains the influence of bending stiffness of cables on their internal forces. Furthermore, the text provides information on how this influence can be reduced.
The ASCE 7-22 Standard [1], Sect. 12.9.1.6 specifies when P-delta effects should be considered when running a modal response spectrum analysis for seismic design. In the NBC 2020 [2], Sent. 4.1.8.3.8.c gives only a short requirement that sway effects due to the interaction of gravity loads with the deformed structure should be considered. Therefore, there may be situations where second-order effects, also known as P-delta, must be considered when carrying out a seismic analysis.
Use the "Independent mesh preferred" option in the FE mesh settings to create an independent FE mesh for the integrated objects. This allows you to generate a significantly more detailed and precise FE mesh for individual objects that are integrated into one another.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
In RFEM 6 and RSTAB 9, you have the option to enter "Visual Objects" as guide objects. You can import the file formats 3ds, stl, and obj.
These objects allow you to create a better reference to the dimensions.
Do you have individual column sections and angled wall geometries, and need punching shear design for them?
No problem. In RFEM 6, you can perform punching shear design not only for rectangular and circular sections, but for any cross-section shape.
How do I get the current authorization file for RFEM 5, RSTAB 8, and other stand-alone programs?
After running the program as a full version and working with it for a certain period of time, an error message appears when saving the file, saying that the authorization failed. What is the reason, and how can I save my file anyway?
When starting the program, I get warning message No. 47 "The Dlubal product key does not match your license." How can I use the full version?
When running the project manager according to FAQ 002927, all files are displayed by default. How can I set the option to display only RFEM files without having to click RFEM each time?
The installation of a Dlubal Software program is not possible due to the following message: "Program unsafe, protection by Microsoft Defender SmartScreen". How can I install the program?
I get the following message when starting all installed Dlubal programs (also when running as administrator): "The application was unable to start correctly (0xc0150002)". What can I do?
