货架支架采用工字形截面。 The axial rotation is restricted on both ends while warping is enabled. The structure is loaded by two transverse forces in the middle. The verification example is based on the example introduced by Gensichen and Lumpe.
由四根倾斜杆件和一个竖向杆件组成的平面桁架,在上部节点处施加竖向力和与平面外的力。 Assuming the large deformation analysis and neglecting the self-weight, determine the normal forces of the members and the out-of-plane displacement of the upper node.
一个对称的浅结构结构,由八个相同的桁架构件组成,这些桁架嵌在铰支座中。 The structure is loaded by a concentrated force and alternatively by imposed nodal deformation over the critical limit point when the snap-through occurs. Imposed nodal deformation is used in RFEM 5 and RSTAB 8 to obtain the full equilibrium path of the snap-through. The self-weight is neglected in this example. Determine the relationship between the actual loading force and the deflection, considering large deformation analysis. Evaluate the load factor at the given deflections.

在两个支座之间悬挂一根非常刚的绳索。 Determine the equilibrium shape of the cable (the catenary), consider the gravitational acceleration, and neglect the stiffness of the cable. Verify the position of the cable at the given test points.
柱由截面混凝土(矩形100/200)和钢截面(截面 I 200)组成。 It is subjected to pressure force. Determine the critical load and corresponding load factor. The theoretical solution is based on the buckling of a simple beam. In this case, two regions have to be taken into account due to different moments of inertia and material properties.
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.
该梁固定在矩形截面,并在其作用下竖向固定偏心。 Considering the small deformation theory, neglecting the self‑weight, and assuming that the beam is made of isotropic elastic material, determine the maximum deflection.
定义一个简单振动器,由质量 m(只考虑 x 方向)和刚度为 k 的弹簧组成。 The mass is embedded on a surface with Coulomb friction and is loaded by constant-in-time axial and transverse forces.
