In the Construction Stage Analysis (CSA) add-on, you have the option to modify the object and design properties of members, surfaces, and so on, in the individual construction stages.

When calculating regular structures, data input is often not complicated, but it is time-consuming. Save your valuable time with input automation. The task described in the present article is to consider the stories of a house as single construction stages. Data are entered using a C# program so that the user does not have to enter the elements of the individual floors manually.
The Construction Stages Analysis (CSA) add-on allows for the design of member, surface, and solid structures in RFEM 6 considering the specific construction stages associated with the construction process. This is important since buildings are not constructed all at once, but by gradually combining individual structural parts. The single steps in which structural elements, as well as loads, are added to the building are called construction stages, whereas the process itself is called a construction process.
The calculation of complex structures by means of finite element analysis software is generally performed on the entire model. However, the construction of such structures is a process carried out in multiple stages where the final state of the building is achieved by combining the separate structural parts. To avoid errors in the calculation of overall models, the influence of the construction process must be considered. In RFEM 6, this is possible using the Construction Stages Analysis (CSA) add-on.
This article provides a detailed overview of the export features from RFEM 6 and RSTAB 9 to AutoCAD/DXF files, including options for exporting dimensions, FE meshes, and deformed shapes.
During the calculation, you can use the Calculation Progress window to graphically display the model deformation for the calculation steps.
In the wind simulation, it is possible to consider member coatings (for example, from ice loads).
If you activate the "Link to Nearby Objects…" option for nodes, RFEM or RSTAB automatically searches for neighboring objects. A link in the form of a rigid member is then created for these members, nodes, or surfaces.
You can specify various settings for searching for nearby objects. Including search area, object types to be searched for, and objects to be excluded. Furthermore, you can specify member hinges for the created connecting member.
The Cable on Pulleys member type allows you to simulate a cable system deflected by pulleys.
This member type only absorbs tensile forces and can only be displaced in the longitudinal direction. It is suitable for flexible tension elements whose longitudinal forces are transferred through the model via deflection points (for example, a pulley).
How can I perform member design by case for different settings in the design configuration?
Is it possible to change the properties of members or surfaces, such as their location, in the individual construction stages?
In the Steel Joints add-on, I receive high design ratios for prestressed bolts for the tension force design.
Where does this high design ratio come from and how can I evaluate the bolt's load-bearing capacity reserves?
Can I optimize parametric cross-sections?
How can I define RSECTION cross-sections in Grasshopper?
How can I fix the error warning “10060 - The structure is unstable” for modal analysis instability?
