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.
When calculating the internal forces for the buckling analysis with the method based on nominal curvature in RF-CONCRETE Columns, the required eccentricities have to be determined.
With RF-/CONCRETE Columns, it is possible to determine effective lengths for columns automatically. This article describes which entries are necessary and how the calculation of the effective lengths is carried out.
Since the ultimate limit state of beams in the area of openings is affected, particular attention should be payed to this. In general, small openings can be sufficiently covered by adapting the beam structure to the openings. For big openings, it is necessary to consider and model the area separately.
In the construction process, it is often necessary to fabricate the concrete elements in sections. A classic example of this production in sections is the use of prefabricated downstand beams, in which the slab is completed in the on‑site concrete construction. By creating a new concrete area, interfaces may arise between the already hardened concrete and the fresh concrete. The transfer of the longitudinal shear forces arising between the partial cross‑sections must be considered in the design.
Determination of Minimum Reinforcement for Centric Restraint on Thick Structural Components According to EN 1992-1-1
In general, avoiding cracking in concrete structures is neither possible nor necessary. However, cracking must be limited in a way that the proper use, appearance and durability of the structure are not affected. Therefore, limiting the crack width does not mean preventing crack formation, but restricting the crack width to harmless values.
In order to use internal forces from average regions also for design of concrete surfaces, you have to activate them in the module. For this, click the [Details] button in the “Tools” tab and select the option “Apply the averaged internal forces in the defined average region for the ULS calculation and for the analytic method of SLS calculation”.
At first glance, the material list for masonry seems to be empty. The reason for this is that bricks and mortar can be used in many combinations, which would lead to a very long and unclear list. Therefore, it is necessary to first create a new material for masonry in order to consider these possible combinations in the calculation.
Sometimes, a model in the graphic window is displayed without filling the entire window or with too large margins after clicking the [Show Whole Model] button. In order to set the size of the graphic margins, click “Options” → “Display Margins and Stretch Factors”. The value specifies the percentage of the margin relative to the graphic window size.
If a section is not on a straight line but on a curved or angled line, this line has to be defined as a polyline or a curved line accordingly. You can define the section along a line by using the “Create Section Numerically” function.
