Large-scale models are models which contain multiple dimensional scales and thus are demanding on computational power. This article will show you how to simplify and optimize the calculation of such models with respect to the desired results.
This article shows you how to use the add-on Optimization & Costs / CO2 Emission Estimation to estimate the model costs. Furthermore, it shows you how to optimize parameters based on minimum cost when working with parameterized models and blocks.
When optimizing cross-sections in the add-on modules, you can also select arbitrarily defined cross-section favorites lists - in addition to the cross-sections from the same cross-section series as the original cross-section.
In RF-PUNCH Pro, you can perform the punching shear design on wall corners and wall ends. The basis for the design is the punching load, which is automatically determined from the RFEM internal forces in the connected surface. Since the surface internal forces from the RFEM calculation may be subject to the influence of singularity locations, this can also have a negative influence on the determined punching load at the wall corner or end. This article describes possible optimization options that you can use to minimize this unfavorable influence.
This article is about the stability analysis of a steel column with axial compression according to EN 1993‑1‑1, Clause 6.3.1. Additionally, a variation study is carried out aiming at steel optimization.
Part 4.1 of this article series describes the connection of the RF‑/STEEL EC3 add‑on module; the members and load combinations to be designed were already defined. This section will focus on the optimization of cross‑sections in the module and the transfer to RFEM. The elements already explained in the previous parts are not described again.
Sections 4.1 and 4.2 of this article series describe the optimization of a frame using the RF‑/STEEL EC3 add-on module. The fifth section explains how to link the module and get the relevant members. The elements already explained in the previous sections will not be described again.
During the optimization of a structure, the individual cross‑sections may have to be modified several times. This can be done very quickly using the function "Assign Graphically to Members", which is available under "Cross‑Sections" in Project Navigator – Data.
Various optimizations are available with program version x.06.1103. The RF-/FOUNDATION Pro add-on module has also been subjected to further development.
