摘要
A geometrically linear slender system subjected to an active and passive specific load is discussed. The boundary conditions, which take into account the specific load, were derived on the basis of the boundary conditions for the general load (the load present at the ends of the column induced by a longitudinal and transversal force, as well as by the concentrated moment). The boundary value problem of the basic system (the system subjected to a generalized load) was formulated using Hamilton's principle. With regard to the specific load, the column was investigated for two types of active load: a generalized load by a force directed toward the positive pole, and a load by the follower force with a circular contour directed toward the positive pole. Heads consisting of linear elements were used to realize the active load, whereas heads consisting of circular elements were used to realize the passive load by the follower force directed toward the positive pole. Numerical research concerning the critical load and characteristic curves was carried out for different values of the parameters of the considered columns. The accuracy of the assumed mathematical model is confirmed by experimental research.
