Automatic effective length calculation

    Correct. Assigning design parameters is currently in the domain of the analytical workflow.

    But currently this is not how it is set up, right? The physical modeler does everything but set up the design parameters. Which is still done in the Analytical modeler.

    I just want to make sure that I am not missing some functionality within the physical modeler that could make my life easier.

    The first step in this solution will be for the Physical Model to take ownership of setting design parameters. That means that similar to modelling and geometry functions, that becomes restricted in the analytical environment. Then we can build a system that can automate the parameters for various attributes such as effective length and deflection lengths.

    Just for clarification, does the physical model tell the analytical model the Lx, Ly, and Lz values? Likewise, does it also tell it DJ1 and DJ2 values? My understanding of the modeling was that it doesn't do that. At least if I view the design commands in the analytical model (after converting from the physical model), it won't have those values defined.

    I feel like the poster was asking for something like that.

    Thank you for your post. I think the first part is really about accounting for the fact that you are looking to retain the concept of a physical beam or column even if it has to be sub-divided for analytical purposes. That is already addressed by defining your model in the physical workflow. If I understand correctly, your suggestion in the second and third points is about automatically calculating the effective length factors, we do have this in our backlog. The factors themselves being determined by the stiffness of the members that it is connected to in the two orthogonal axes.

    In staad pro CE, in analytical modeler, when we add new node/s,the existing member is devided into segments, and the program takes length/effective length of that member as part, not takes as a whole member length about its major or minor axis accordingly, so my suggestion is that, 1-kindly add the features that program automatically take the length of member (beams and columns)as per its division on major or minor axis accordingly...... 2- like steel structure, the effective length of beams and columns should be automated in RCC structure 3-Also in steel structure design effective length factor Ky and Kz is to be provoided manually after confirming moment release or reatrained, translation is release or restrained, and also the major and minor axis, this manual efforts is so applied to each and every member and thqt is time consuming, error prone and tedious, so kindly add that feature.
