Тонкая прямоугольная ортотропная пластина оперта просто, и она загружена равномерно распределенным давлением. The directions of axes x and y coincide with the principal directions. While neglecting self-weight, determine the maximum deflection of the plate.
Данный пример служит для демонстрации ограничения диафрагмы. 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.
Цель данного примера - продемонстрировать необратимые процессы, вызванные трением. 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. Собственный вес не учитывается. The frequencies, mode shapes, and equivalent loads of this 5-DOF system are analytically calculated and compared with the results from RSTAB and RFEM.
