本例题介绍的是膜板约束。 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.
左端支承一个 I 形截面的悬臂梁,图中显示了扭矩荷载。 The aim of this example is to compare the fixed support with the fork support and to investigate the behavior of some representative quantities. Comparison is also made to the solution by means of plates. Small deformations are considered, and the self-weight is neglected. Determine the rotation in the midpoint of the cantilever, and in case of the member entity with warping, determine the values of the primary torsional moment, the secondary torsional moment, and the warping moment both on the left end (point A) and the right end (point B).
一层正交各向异性方形板的中点完全固定,并施加压力。 Compare the deflections of the plate corners to check the correctness of the transformation.
