A simply supported beam is loaded by pure bending. Devido à encurvadura por flexão, tente determinar a carga de encurvadura crítica e o fator de carga correspondente.
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.
Considere o vão da barra ASTM A992 W 18×50 apresentado na Figura 01 e as cargas permanentes e variáveis uniformes. The member is limited to a maximum nominal depth of 18 inches. The live load deflection is limited to L/360. The beam is simply supported and continuously braced. Verify the available flexural strength of the selected beam, based on LRFD and ASD.
A thin rectangular orthotropic plate is simply supported and loaded by uniformly distributed pressure. The directions of axes x and y coincide with the principal directions. Determine a flecha máxima do painel, sem considerar o peso próprio.
A structure made of an I-profile is fully fixed on the left end and embedded into the sliding support on the right end. A estrutura é constituída por dois segmentos. 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.
Imaginemos um tubo de andaime resistente à flexão fixado por um apoio nodal para andaimes na parte inferior e carregado por um momento e por uma força. Calculate the maximum radial deflection by exceeding the capacity of the scaffolding support.
A structure made of I-profile trusses is supported on both ends by spring sliding supports and loaded by transversal forces. O peso próprio não é considerado neste exemplo. 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.
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).
