• RE: What is the difference between ITERDIRECT and PDITER options for PERFORM DIRECT ANALYSIS command?

    There are two types iterations that happen in a DIRECT ANALYSIS. Taub iterations and Pdelta iterations. ITERDIRECT controls the number of iterations for Taub whereas PDITER controls the number of iterations for the pdelta. The pdelta iterations are nested…

  • RE: Perform Direct Analysis for Serviceability and Strength design in one Staad file

    The stiffness is automatically reduced. The REDUCED EI option is only to tell the software whether to consider the reduced stiffness for the calculation of intermediate section displacements and moments. By default the reduction is considered for that…

  • RE: Using Floor Diaphragm Command

    The rigid diaphragm is a structural system which has infinite in-plane stiffness used to transfer lateral loads to shear walls or frames primarily through infinite in-plane stiffness.

    Usually, the floor system or roof system in a RCC building, or the…

  • Loads Definition is gray out in Staad Pro

    Dear friends,

    I don't know if it is a bug in the new release of Staad Pro or if I am doing something wrong.

    When I send a model from the Physical Model to the Analytical model the Loads Definition tab has its bottom grey out, see:

    As you can see…

  • RE: Loads Definition is gray out in Staad Pro

    Correct. If you drop the physical model, you will lose the connection between the analytical and the physical model. However at this point of time if generating the loads and adding loads in the analytical modeler is a requirement, then that is the only…

  • Repeat Load from Reference Loads

    I've looked through the manual and the forum here and haven't found a definitive answer.  Can repeat loads be made from reference loads or can they only be made from primary load cases?  The reason I ask is if you add a new load, reference loads…
