This article deals with the stiffness of standardized joints according to the DSTV (German Steel Construction Association)/DASt (German Committee for Structural Steelwork) standards, often used in steel construction, and its effects on structural analysis and design results according to DIN EN 1993-1-1.
In RFEM and RSTAB, several interfaces are available. The DSTV interface (*.stp) is the most convenient for importing beam structures, since supports, hinges, loads, and load combinations are also transferred, in addition to the general topology.
Starting with version X.05.0018, you can also analyze moment-resistant beam-column connections in RF‑/JOINTS Steel - DSTV. Both single-sided and double-sided connections are possible. In compliance with the DSTV guidelines, the program checks (with respect to the loading) whether the existing column cross‑section is dimensioned sufficiently. Optionally, you can transfer the rotational stiffness and the eccentricity of the connection to RFEM or RSTAB.
