• Steel Deflection Check in STAAD Select 6

    Dear All, Previous version(Select5) STAAD.PRO, I could find beam deflection data in result report by DFF parameter and Track 1. (AISC 360-05) But Select6, I can not find deflection data in result report. Is deflection result removed? If it is…

  • RE: DEFLECTION COMMAND IN STAAD

    Any deflection check limit would always be set using the DFF parameter. So for span/240 you would set DFF as 240 and for span/150 you would set DFF as 150. You will get failures in design if deflection check fails and in such cases DEFLECTION would be…

  • Deflection check

    Hei!, I have a question regarding deflection check. When I have a structure of let say 4 nodes (1 column of 1.5 m supported by fixed support at bottom + 2 beams connected to each other as "L" shape each one of 0.25 m) , choosing whatever steel profiles…

  • RE: Checking max deflection?

    In case you are interested in checking the deflection graphically, you can double click on the member and check the values as shown next. The diagram is annotated with the max deflection value.

  • Checking max deflection?

    Hello all, I'm a student learning STAAD.Pro this semester. I've done a beam model with two point loads applied. I've analyzed the model, but I haven't seen an output for what the actual value of max deflection in the beam is. How does STAAD display…

  • STAAD.Pro deflection interpretation in member query box

    Hi, I am using STAAD.Pro v8i (select series 5). I would like to know more about how to interpret the "Deflection" tab in the member query dialog box (the box that comes out when you double click on a member using the member select tool). Specifically…

  • Identify cracked elements in RAM Concept

    Is there a way to identify/see/plot which elements in a flat RC slab are cracked at the end of RAM Concept's analysis? I'd like to be able to compare the deflection results that RAM Concept calculates with those produced by a consultant in a generic…

  • RAM Concept Load History Deflections

    We are currently working on a RC garage model (11” slab thickness, max span ≈34’). We are noticing that our load history deflections are much larger than we are expecting. When we run load history deflections we get a Final Instantaneous Deflection…

  • RAM Concept Long Term Deflections

    Hi, I am new to RAM Concept. I have created my model and have gotten deflections for my load cases. I was wondering if there was a way to get the long term deflections as well? And if so how would I go about doing this?

  • deflection check for column in staad

    Pls someone help me to get more understanding for deflection check cal. in staad. What i found the results in staad with DFF command is like that deflection result can get for column in Global X direction and for beam in Global Y direction. …

    To begin with, the design commands that I specified are generic and can be used for any code for example CODE AISC UNIFIED 2010 METHOD ASD ( or LRFD ) would use the ASD or LRFD design as per AISC 360-10. CODE AISC UNFIED 2005 METHOD ASD ( or…

  • STAAD.PRO Deflection Issues

    I have a simply supported beam that is split in two. The beam has a 100 k/ft uniform load. When I check the deflection values, I notice that the maximum deflection is 0.382 inches which is different than the deflection I calculated by hand (0.272 inches…

  • Lambda Critical and Amplified Sway Method to BS 5950-1

    All, I am looking for some guidance, when determining the lambda critical value for a structure within RAM Frame, does the programme do anything with this? In particular, if the lambda critical value is less than 10, but greater than 4, does the…

  • Long Term Deflections RAM Concept

    When looking at the long term deflections in RAM Concept, not using the Long Term Load History calculations. I check the Service Design rule set and under Section analysis, I check the selector called Long Term Deflection, This appears to take the elastic…

  • STAAD.PRO Selfweight Loading

    I have a model that is 3-D (space) and I have applied a selfweight load only in the downward direction. I get deflection in the y direction, but why do I get deflection in the x and z directions as well?

  • Composite Beam Deflection Query

    I am designing a composite floor system as my first project in RAM. As I was looking at the composite beam deflections and checking them to make sure I understood and agreed, it seemed that the Post-Composite Beam Deflections for a S-S beam with a UDL…

    So from reading the RAM Concept Load History Calc Options Technote it appears that the shrinkage restraint will just adjust the cracking values of the concrete floor for long term load history calculations is this correct? For instance if I have a floor…

  • Re: Deflection serviceability check and resulting load case

    It would be good to get another file with multiple cases that also exhibits the problem. In some files I tested, the Post-Processing table for Unity Check lists the correct L/C even when deflection controls. Meanwhile, I think you can use the Report …
