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.
In accordance with Sect. 22.214.171.124.1 and Sect. 10.14.1.2 out of the ACI 318-14 and CSA A23.3-14 respectively, RFEM effectively takes into consideration concrete member and surface stiffness reduction for various element types. Available selection types include cracked and uncracked walls, flat plates and slabs, beams, and columns. The multiplier factors available within the program are taken directly from Table 126.96.36.199.1(a) and Table 10.14.1.2.
With RF-FOUNDATION Pro, it is possible to determine settlements of single foundations and resulting spring stiffnesses of the nodal supports. These spring stiffnesses can be exported into the RFEM model and used for further analyses.
When designing reinforced concrete components according to EN 1992‑1‑1 , nonlinear methods of determining internal forces for the ultimate and serviceability limit states are possible. The internal forces and deformations are determined by considering the nonlinear internal forces-deformation behavior. The calculation of stresses and strains in the cracked state usually results in deflections that are significantly higher than the values determined linearly.
In the case of a huge amount of reinforcement, it might be useful to grade the longitudinal reinforcement of a beam, which means: curtailment. The grading corresponds to the tensile force distribution. Using RF-CONCRETE Members and CONCRETE, you can specify the curtailment of the reinforcement, which is considered in the automatically proposed reinforcement for the longitudinal reinforcement. When determining this reinforcement proposal, it is necessary to ensure that the envelope of the acting tensile force can be absorbed.
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.
As of RFEM 5.6.1103 and RSTAB 8.6.1103, there is an improved result output for nonlinear calculation of reinforced concrete design in RF‑CONCRETE Members and CONCRETE. The new result windows include tables with a wide range of loading results, for example governing load with the maximum ratio. In addition, it is now also possible to display the envelope results for the maximum ratio graphically.
As of the program version X.06, you can set in RF‑CONCRETE Members or CONCRETE whether the crack width analysis should be performed in any case or only when exceeding the effective tensile strength of concrete.
It is possible to export the national parameters of EN 1992‑1‑1 for each country from RF‑/CONCRETE, RF‑/CONCRETE Columns and RF‑/FOUNDATION Pro. For this, there are the interfaces with MS Excel, OpenOffice, and CSV. By exporting the national parameters, you can edit them in MS Excel, for example, and display possible differences between the individual National Annexes in a clear way (see Figure).
Using the [To Display...] button, it is possible to specify the amount of reinforcement to be displayed in the results of the required reinforcement in Window 2.2 of RF‑CONCRETE and CONCRETE. In addition to the default setting, you can display the resulting reinforcement amount in this way, for example the sum of longitudinal and longitudinal torsion reinforcement or the sum of torsion and shear reinforcement. You can also reduce the number of preset results, of course.
In CONCRETE and RF‑CONCRETE Members, you can open a dialog box with a 3D rendering of the existing reinforcement in Window 3.1 or 3.2. Now, it is also possible to display different reinforcement views in several dialog boxes at the same time. The ‘Isometric and 3 Views’ option known from RFEM is available here as well.
