Ein Kehlbalken Dach mit gewählter Geometrie wird in Hinblick auf seine Schnittgrößen zwischen Berechnung mittels RFEM 6 und der Handrechnung verglichen. Dabei werden insgesamt 3 Lastsysteme untersucht.
Un sistema de una sola masa con juego y dos muelles se deforma inicialmente. Determine the natural oscillations of the system - deflection, velocity, and acceleration time course.
Este ejemplo de verificación se basa en el ejemplo de verificación 0122. A single-mass system without damping is subjected to an axial loading force. An ideal elastic-plastic material with characteristics is assumed. Determine the time course of the end-point deflection, velocity, and acceleration.
Un oscilador de doble masa consta de dos muelles lineales y masas, que se concentran en los nudos. The self-weight of the springs is neglected. Determine the natural frequencies of the system.
Un sistema de doble masa consta de dos ejes y dos masas representadas por los momentos de inercia correspondientes, concentrados en una distancia dada como masas en nudos. The left shaft is fixed, and the right mass is free. Neglecting the self‑weight of the shafts, determine the torsional natural frequencies of the system.
A cantilever beam with an I-beam cross-section of length L is defined. The beam has five mass points with masses m acting in the X-direction. Se omite el peso propio. The frequencies, mode shapes, and equivalent loads of this 5-DOF system are analytically calculated and compared with the results from RSTAB and RFEM.
