A strut with a circular cross-section is supported according to four basic cases of Euler buckling and subjected to pressure force. Determine a carga de encurvadura crítica.
A column is composed of a concrete section (rectangle 100/200) and a steel section (profile I 200). Está sujeito a uma força de compressão. 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.
A viga em consola com um perfil em I está apoiada na extremidade esquerda e é carregada com um binário. The aim of this example is to compare the fixed support with the fork support and to investigate the behavior of some representative quantities. Comparison is also made to the solution by means of plates. Small deformations are considered, and the self-weight is neglected. Determine the rotation in the midpoint of the cantilever, and in case of the member entity with warping, determine the values of the primary torsional moment, the secondary torsional moment, and the warping moment both on the left end (point A) and the right end (point B).
A viga de aço carregada axialmente com uma secção quadrada está apoiada sobre uma articulação numa das extremidades e sobre uma mola na outra extremidade. Two cases with different spring stiffnesses are considered. The verification example solves the calculation of the load factors of the beam in the image using the linear stability analysis.
