Analysis Of The Continuous Rigid Frame Bridge Response In Ship Collision Force

The main contents of this research is the analysis of the Continuous rigid framebridge response in ship collision force. Ship bridge collision is a dynamic process inessence, occurring in a short period of time (usually2seconds or so). during thisprocess, the collision force changes continuously all the time. At present nationalcode and much of the simplified computational theory always assumed the shipcollision force to be static, but a static to the bridge cause a result of the static forceand static displacement, the collision force time history to the bridges, the dynamicforce and displacement, sometimes the difference between the two will be greater.Aiming at the large span continuous rigid frame bridge, this research built threecontinuous rigid frame bridges models with Midas, the span and heightof this threecontinuous rigid frame bridges changes gradually. and then choose three positions inevery bridge, enter a known5000tons of boat of ship-bridge time-history collisioncurve, the equivalent static load of the curve, peak load and the calculate static loadaccording to American Standard, study the pier top displacement, the displacement ofcross, cross of pier bottom shear, shear, bending the pier bottom several parameters,study the parameters of ship collision with bridges when the impact is bigger, so as toto provide a reference for the ship bridge collision design.
