Hi, I`m using SAP-17 to build a bridge model. I don`t have the bridge modeler license, so making the bridge from scratch in sap2000. The bridge is a steel girder bridge with concrete deck (composite system). However between the stiffeners in transverse direction there are lateral bracings...

First Q: I believe you need to define a separate spring for each level of soil with different stiffness at each level. Second Q: To show your moving load, I believe you can look at your vehicle load, and how you have defined that. The loading doesn't show on your model as it's a moving load...

Hi, I'm modelling an LNG platform. The model is pretty straight forward, a concrete deck, supported on steel piles, with nonlinear soil springs. I need to model the loading arms and other equipments on the deck to look at the seismic behavior of the structural with the additional mass on its...

I am trying to model a steel deck attached to a steel frame in SAP2000. This model is supposed to model a roof system. Instead of the bolts used in the actual test, I am using non-linear plastic links to attach the top surface to the frame. In the actual test, I have cyclic loading with max...
