WebM m a x = P L 4 and V m a x = P. 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 …
