I am applying vertical ground motions via non-linear time history analysis to a suite of single span bridges. to model the vertical properties of the bearing I am using a gap element to replicate the real world situation where there is virtually no resistance to uplift provided by the bearing...
Has anyone ever had CSIBridge or SAP2000 crash during an analysis and get either of the following messages?

I am analyzing prestress i-girder bridges under 48 different ground motions using nonlinear modal time history. I have tried using both area object model and spine model. Also I...
Does anyone know what the best way to model this type of bearing is? It is a elasomeric pad with 2 steel dowels to prevent 'walking'. Figure 1 shows what I need to define. I have tried multilinear plastic link but did not get good results, my link definition is figure 2.

I am subjecting a single span precast prestress concrete I-beam bridge to longitudinal ground motions. when i specify a stiffness for the bearings in the transverse direction, the abutment longitudinal displacement becomes smaller than expected. when the transverse bearing stiffness is set to...
Hello,
I am modeling a single span prestressed I-beam bridge in CSI Bridge(Basically SAP2000). I am going to subject the model to ground motions using nonlinear time history analysis. I need a way to model the effect of the passive earth pressure resistance acting on the abutment backwall when...
