Two Moving Loads. For two moving loads, the maximum shear occurs at the reaction when the larger load is over that support. The maximum moment is given by. M m a x = ( P L − P s d) 2 4 P L. where P s is the smaller load, P b is the bigger load, and P is the total load (P = P s + P b ). Three or more …

Webframed as conventional and non-moving moving load problems. Treating them as a moving load problem involves more advanced mathematics and computation. The dynamic effect of moving loads was not known until mid-19th century. When the Stephenson’s bridge across river Dee Chester in England in 1947 collapsed, it motivates … Web27 de abr. de 2015 · However, for problems in which such condition is not fulfilled (i.e. for the case of arbitrary arranged grid points), especially for moving load class of problems, the coupled approach may fail to produce accurate solutions. To solve this drawback, we also introduce two simple approximations and show that they can yield accurate results.
