Members can be checked for either an elastic or plastic analysis, second order analysis, for tension, compression, bending and shear as well as torsion and warping torsion. For Cold formed Steel sections, which can also be designed, see section below for more details. Non-standard sections can also be user input and checked. The range of member types is extensive and includes members that are tapered or with holes, unsymmetric sections, pairs and built-up sections as well as welded profiles (welds are designed also in this case). Results are displayed graphically on the model. Members can either be checked for capacity or automatically designed for optimum section size. The program can design steel structures such as steel buildings, steel halls, scaffolding, bridges, silos, cranes, crane runways, masts, winter gardens, etc. RFEM performs all characteristic designs of the ultimate and serviceability limit states as well as stability and deflection analyses, fire resistance check, for steel members according to the Eurocode EN 1993. As advances in structural design result in more efficient and lighter irregular structures, sensitivity to vibration of the structures is becoming increasingly significant. Footfall response is of interest to users concerned about the vibration induced in their structures due to walking related activities. – Nonlinear dynamic analysis to external excitationsĬADS Footfall Analysis (CFA) is post-processing software that is used in conjunction with Dlubal RFEM to provide footfall response analysis calculation. – Seismic and static load analysis using the multi-modal response spectrum analysis – Dynamic and seismic analysis including time history analysis and multi-modal response spectrum analysis
– Dynamic analysis of natural frequencies and mode shapes of member, surface, and solid models. Typical application areas for dynamic analysis are seismic design, vibration design of buildings, calculation of machine foundations as well as natural frequency analysis of bridges and chimneys.
