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.
在给定的边界条件下,杆件受到扭矩和轴力。 Neglecting its self-weight, determine the beam's maximum torsional deformation as well as its inner torsional moment, defined as the sum of a primary torsional moment and torsional moment caused by the normal force. Provide a comparison of those values while assuming or neglecting the influence of the normal force. 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.
在两端铰接的梁的中间施加集中力。 Neglecting its self-weight and shear stiffness, determine the beam's maximum deflection, normal force, and moment at the mid-span, assuming the second- and third-order analysis.
