Re: How to eliminate tension springs in SAP2000

[Subject Prev][Subject Next][Thread Prev][Thread Next]
        One crude way that you can rely on (if you can not find a better way) is to analyze it with normal springs then delete (or make inactive) all of the springs in tension and reanalyze it without those elements acting.

Subject: How to eliminate tension springs in SAP2000

In SAP2000 software in assigning area spring to shell elements, there are available both "tension-compression" and "compression-only" springs, But even if "compression-only" is selected, in output results, tension is developed in springs. I don't know how we can model and analyze compression only springs to exactly model the soil-foundation contact situation.
