![]() Secondly a transient analysis is performed to determine the accelerations of the bridge deck, when it is loaded by dynamic load models of the Eurocode and an alternative moving load. To obtain the publication for a nominal fee click HERE. With MIDAS/ Civil two analyses are performed: Firstly a modal analysis to compute the natural frequencies of the bridge and the coinciding vibration mode shapes. that MIDAS/Civil uses for pushover analysis are 2D beam element, 3D. This can help you model a bridge of this nature by yourself on Staad Pro with full support of our technical team peradventure you need further help in getting it done. Moving Load Analysis for Bridge Structures / 225 Traffic Lane and Traffic Surface. ![]() We have prepared a 21 page manual on how you can model a complete simply supported one-span bridge on Staad Pro. We can apply the tandem load of EN 1991-2 on the bridge deck in order to obtain the critical bending moment and shear forces. Let us consider a bridge deck with the configuration shown in Figure 1 Fig 1: Bridge deck configuration Other publications such analysis of bridge deck girders under Load Model 1 using Staad Pro can also be considered to enhance your knowledge on the topic. ![]() You can also read on how you can carry out grillage analysis of bridges using Staad Pro. In the past, we have made publications on how you can apply Load Model 1 of EN 1991-2 on highway bridges.
