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.
左端是一个完全固定的工字形截面结构,右端是嵌在可滑动支座中的结构。 The structure consists of two segments. The self-weight is neglected in this example. Determine the maximum deflection of the structure, the bending moment on the fixed end, the rotation of segment 2, and the reaction force at point B by means of the geometrically linear analysis and the second-order analysis. The verification example is based on the example introduced by Gensichen and Lumpe.
一个 QRO 型薄壁悬臂梁左端完全固定,并且翘曲激活。 The cantilever is subjected to torque. Small deformations are considered, and the self-weight is neglected. Determine the maximum rotation, primary moment, secondary moment, and warping moment. The verification example is based on the example introduced by Gensichen and Lumpe.
该结构由 I 型桁架组成,两端通过弹簧支撑,并承受横向力。 The self-weight is neglected in this example. Determine the deflection of the structure, the bending moment, the normal force in the given test points, and the horizontal deflection of the spring supports.
