Rozważ belkę ASTM A992 W 18×50 dla stałych i równomiernych obciążeń stałych i ruchomych, jak pokazano na Rysunku 1. 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.
Układ jednomasowy z dashpotem jest poddawany stałemu obciążeniu. 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.
Konstrukcja z profilu I jest w pełni utwierdzona na lewym końcu i osadzona w podporze przesuwnej na prawym końcu. 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.
Rozważmy sztywną rurę rusztowania, zamocowaną u dołu za pomocą podpory węzłowej rusztowania i obciążoną zarówno momentem, jak i siłą. Calculate the maximum radial deflection by exceeding the capacity of the scaffolding support.
Długa, cienka belka przenosi masę skupioną i jest obciążona siłą zależną od czasu. It is simply supported. The problem is described using the following parameters. Determine the deflections in the given test times.
Konstrukcja wykonana z kratownic o przekroju dwuteowym jest podparta na obu końcach za pomocą sprężynowych podpór przesuwnych i obciążona siłami poprzecznymi. 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.
Wspornik o profilu dwuteowym jest podparty na lewym końcu i obciążony momentem obrotowym. 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).
