该结构由一个工字钢和两个桁架组成。 The structure contains several imperfections and it is loaded by the force Fz. 示例中忽略自重。 Determine the deflections uy and uz and axial rotation φx at the endpoint (Point 4). 验算示例是基于 Gensichen 和 Lumpe 介绍的示例.
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.
假设在脚手架底部设置了一个刚性圆筒,该圆筒由一个弯矩和一个力来定义。 Calculate the maximum deflection with consideration of initial slippage.
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.
假设在脚手架底部设置了一个刚性圆筒,该圆筒由一个弯矩和一个力来定义。 Calculate the maximum radial deflection by exceeding the capacity of the scaffolding support.
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.
该模型初始定义了一个具有间隙和两个弹簧的单质量系统的柔性体系。 Determine the natural oscillations of the system - deflection, velocity, and acceleration time course.
施加力时施加在单个质量系统上。 Determine the deflection of the system.
图1所示 Verify the available shear strength of the selected beam, based on LRFD and ASD.
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.
施加阻尼器的单质量系统受到恒定的力。 Determine the spring force, damping force, and inertial force at the given test time. In this verification example, the Kelvin--Voigt dashpot (namely, a spring and a damper element in serial connection) is decomposed into its purely viscous and purely elastic parts, in order to better evaluate the reaction forces.
一个悬臂梁,完全固定在左端,在其右端施加横向力和轴向力。 The tensile strength is zero and the behavior in the compression remains elastic.
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.
选择 W 形杆件,自重为 30.000 牛/牛, Verify the member strength using both LRFD and ASD.
