Lateral x-bracing in many truss bridges is detailed and intended to act as tension bracing. While the other half of the X may i initially attract some compression, it quickly elastically buckles and becomes ineffective (until the lateral load is removed).

I haven't used SAP for a long time -- it may have a "tension only" member option, or you may choose to manually omit some of the bracing as shown.
