该验算示例是基于验算示例 0122 编写的. 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.
验算示例描述了作用在建筑物模型上多个风向的风荷载。 The model consists of eight cubes. The velocity fields obtained by the RWIND simulation are compared with the measured values from the experiment. The experimental data are measured using a thermistor anemometer in the wind tunnel.
施加集中质量的细长梁,并施加一个随时间变化的力。 It is simply supported. The problem is described using the following parameters. Determine the deflections in the given test times.
在一根方形截面的钢梁上施加轴力和均布荷载。 The image shows the calculation of the maximum bending deflection and critical load factor according to the second-order analysis.
对厚壁容器施加内部压力,使得该容器达到弹塑性状态。 While neglecting self‑weight, the analytical and numerical solutions for the radial position of the plastic zone border (under the Tresca hypothesis) are determined and compared.
该类型的悬臂梁截面为矩形,在端部有一个质量块。 Furthermore, it is loaded by an axial force. Calculate the natural frequency of the structure. Neglect the self‑weight of the cantilever and consider the influence of the axial force for the stiffness modification.
在两个同心圆柱体的两个半径半径之间的各向同性预应力拉伸膜,该预应力位于一个不与竖轴平行的平面上。 Find the final minimum shape of the membrane - the helicoid - and determine the surface area of the resulting membrane. The add-on module RF-FORM-FINDING is used for this purpose. Elastic deformations are neglected both in RF-FORM-FINDING and in the analytical solution; self-weight is also neglected in this example.
