Ein Kehlbalken Dach mit gewählter Geometrie wird in Hinblick e seine Schnittgrößen zwischen Berechnung mittels RFEM 6 und der Handrechnung verglichen. Dabei werden insgesamt 3 Lastsysteme untersucht.
Un sistema monomassa con gioco e due molle è inizialmente flesso. Determine the natural oscillations of the system - deflection, velocity, and acceleration time course.
Questo esempio di verifica si basa sull'esempio di verifica 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 oscillatore a doppia massa è costituito da due molle lineari e masse, che sono concentrate nei nodi. The self-weight of the springs is neglected. Determine the natural frequencies of the system.
Un sistema a doppia massa è costituito da due alberi e due masse rappresentate dai corrispondenti momenti di inerzia, concentrate in una data distanza come masse nodali. 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. Il peso proprio è trascurato. The frequencies, mode shapes, and equivalent loads of this 5-DOF system are analytically calculated and compared with the results from RSTAB and RFEM.
