• Staad.pro Tension y "compresion only" springs

    Hi! I am having some issues. I assigned a "plate mat" support to a foundation, and i activated the "compression only" option. I made sure that i am defining the combinations with de "repeat load" command. And i am still getting tension in some…

  • RE: Spring supports

    When you use DIRECT Y, then lateral restraints in X and Z are applied automatically. If your intention is to have the supports in vertical directions only at the base plate FE grid nodes, use DIRECT YONLY for those and then the lateral forces would only…

  • RE: How To Model with Considering Soil-Structure Interaction

    You should use FIXED BUT supports that would allow you to define translational and rotational springs. For example SUPPORTS 1 FIXED may be changed to SUPPORT 1 FIXED BUT KFY 301672 KMX 97392 KMZ 97392 The rotational spring stiffness is converted…

  • Spring supports for mat foundation

    Can spring supports be coupled in STAAD?

  • Soil Anchors for seismic footings - tension-only springs?

    1.) I am using RAM Concept to model a seismic footing under a shear wall. This wall is carrying high seismic shear and moment but has relatively low axial load, so it is tending to overturn. One option is to make the footing larger and pick up nearby…
