Influence of Dead Weight and Crane Load on Steel Truss Bridge Closure

Dongjiang Bridge in Dongguan City of Guangdong Province is double-deck and three main trusses steel bridge with rigid cable.Its structure is novel and force property is complex.What′s more,there are more closure points and the closure is difficult.Combining with this project,the influence of dead weight and crane load on steel bridge is analyzed.The results show that the influence of dead weight is obvious,while the influence of crane load is less relatively.
