Sap 2000 V17 or CSI Bridge

[JYip07]

Hi fellow engineers,

I have a task to model and analyze an existing truss swing-bridge applicable loads.

I am not too experienced using SAP 2000 or CSI Bridge so I am unsure what is the difference and which software will suit my needs better.

If somebody knowledgeable can explain to me which software will be sufficient and the differences between the two, that'd be extremely helpful.

Thanks!
