According to the arrangement, under moving load action of the continuous beam, bending moment influence lines generated on different positions are quantitatively obtained, and wide application to the structural mechanics experiments of high engineering colleges is achieved.孙立国...
A mass at high speed traversing a uniform, horizontal, continuous beam resting on discrete supports gives rise to critical beam deflection and bending moment responses greater than those for the mass traversing at crawl speed. It is shown herein that these responses are significantly reduced by the...

frequency of the beam is discussed with the design code.It is shown that,for the impact factor,when the effect of positive bending moment is calculated,it is reasonable to use the fundamental frequency,and the 2nd frequency must be used when the effect of negative bending moment is calculated...

(x). Using the Moment-Area Theorem, we will analyze two adjoining spans of this beam to find the relationship between the internal moments at each of the supports and the loads applied to the beam. We will label the left, center, and right supports of this two-span segment L, C, ...
The elastic—full plastic loading curve is for all materials sufficient to explain the strength of beams and beam columns loaded by bending and compression. This theory is extended for the influence of shear stress, and it is shown to be the only way to explain the combined bending-shear stre...
Summary The admittance method is readily applicable to the problem of determining the steady oscillation of a continuous beam of the most general kind due to impressed normal simple harmonic forces, with end thrust or tension present or absent. The method leads to a theorem of three moments, and...
