In this paper, an extended formula for the critical velocity of a uniformly moving load is derived. It is assumed that the load is traversing an infinite beam supported by finite depth foundation under plane strain condition. The critical velocity is extracted by parametric analysis applied on the...

Application ID: 20401 This example shows how to model a load which varies in space and time. A series of load pulses travel along a beam which is supported at equal distances. For some combinations of the traveling speed of the load pulses and the spacing between them, it is possible to...
The response of a Bernoulli-Euler beam supported by a Winkler-type elastic foundation with inertia and subjected to a moving load is investigated. Steady-state solutions are determined for an undamped and linearly damped beam-foundation system. The effects on the response of load velocity, foundatio...
A beam search algorithm was applied to solve the load-sequencing problem in port container terminals. The algorithm was used to maximize the operational efficiency of transfer cranes and quay cranes (QCs) while satisfying various constraints on stacking containers onto vessels. The load-sequencing prob...
When an axial compressive force is present, the wavelength of the propagating free waves in a beam rapidly decreases. The conventional Euler-Bernoulli beam equations are often not adequate for determining dynamic behavior of the moving load on a beam supported on an elastic foundation when initial ...
If in addition to the transverse (relative to its axis) load p(x, t) a bar is also subjected to a static, time invariable force N applied at the bar's ends along the axis (Fig. 20.1), the fundamental differential equation takes on the form $$EJ\\\frac{{{\\\partial ^4}v(x,t...
A、B两项都是完整的句子,虽然在意思上讲得通,但从结构上无法与句中其他成分相连接,即没有关联词作连接手段;C中虽然从结构上可以接受,但在意义上being用得不够准确。全句译为:”在其他情况保持不变的同时将横梁的宽度加大一倍,其结果是横梁的承受力也加大了一倍。” 知识模块:语法...
