Re: Modeling & Analyzing a moving load with constant speed

In fact, I am trying to model a truss bridge in order to compare the acceleration response of the bridge in healthy and damaged conditions. I wonder how i can model a moving load on a given beam with constant speeds of different values in order to record acceleration and vibration responses. I highl...

Modeling & Analyzing a moving load with constant speed

Hi dear McKenna and Silvia, I am trying to apply a moving load with a constant speed to a beam and perform relevant transient analysis. There are two problem I am facing: 1) It seems that the defined load in each step (each load location) is being added to that of the previous step rather than being...
