Una sottile piastra ortotropa rettangolare è semplicemente supportata e caricata da una pressione uniformemente distribuita. The directions of axes x and y coincide with the principal directions. While neglecting self-weight, determine the maximum deflection of the plate.
Questo esempio serve come dimostrazione del vincolo del diaframma. The application is shown on a two-story structure. The structure is loaded by means of lateral forces according to Figure 1. Determine the maximum deflection of the structure ux in the direction of the loading forces using both the diaphragm constraint and the plate model of the floor.
L'obiettivo di questo esempio è quello di dimostrare un processo irreversibile causato dall'attrito. After the loading and unloading, the end-point is in a different position than where it was at the beginning. Determine the movement of the node in the X direction.
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.
