• 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…

  • Suspension Cable Bridge (Error)

    I tried to model a cable suspension bridge for pipes to cross a river. I tried all the possible solutions but still errors are present. I also wanted to know if the cables i used are capable of carrying the loads i applied.. Please I need help! :(

  • Parameters are not considered while performing tensile rupture strength as per AISC 360-10

    I was going through the staad output. In that while using WT sections, I came to know that axial tension rupture capacity is not multiplied with LRFD or ASD factors. Why is it so? For W sections its showing correct but for WT its not. abc.std

  • Compression coming in cable. How to get around it?

    I am trying to make a cable system which which is originally a tension rod system. However i want to include the prestress in the model therefore I am using cable. I have applied prestress to different region of the structure gradually but still one…

  • RE: STAAD Foundation能计算基础抗拉吗？

    Translation of your question : Is STAAD Foundation able to compute foundation under tension? It is to calculate and check the foundations’ capacity under tension, such as communication tower’s foundations. Response : Yes. STAAD Foundation can design…

  • steel frame building with tension cables

    Good day, I am currently modelling a steel structure that employs the use of tension cable for lateral bracing in addition to an eccentrically braced frame. I have a few queries as it relates to the specification for the cables, which I have listed…

  • RE: Calculating Deflection (P Delta Effects)

    Tension along a linear member does not impact perpendicular deflection in general finite element analysis. One would have to perform a full-blown cable analysis to see the effect of tension in reducing centenary drape. See Help - Contents - Section…

  • RE: STAAD Pro V8i: Dynamic load on light weight structures with tension-only members

    We don't have a good solution for dynamic analysis that honors tension-only (or cable) member settings. If a dynamic analysis is a must, the best thing you can do is assign all those tension-only members to be normal tension + compression members, but…

  • Continuous Cable with Intermediate Cable Supports

    Hi, I am trying to model a continuous cable with 13 intermediate vertical cable supports as well as 2 horizontal supports at the ends. The results don't seem to be making sense, as the supports at the end are only showing the initial tension and no…

  • Potential Error for Tensile Rupture on a WT section in RAM Connection

    I was running a design for a WT vertical brace and found what I believe to be a mistake in the calculation of the shear lag factor, U, for tensile rupture. I have (7) rows of bolts connecting the WT flange to the gusset. From AISC Table D3.1 I would expect…

  • Resolve warning "Zero Stiffness in Direction... at Joint... Eqn. No..."

    I created a model and analyzed. There are 0 errors, but 26 warnings. 24 warnings are "Zero Stiffness in Direction... at Joint... Eqn. No..." and the other two are "There were more than 12 DOF with zero stiffness". How can these warnings be resolved…
