• Tension only and Truss Specification for same members.

    Hi Team, For some reason i am able to assign Tension only and Truss Specification to the same members without any error. I am using STAAD 2023 and i have had no warning while doing the analysis.

  • How can I support the truss by two cable and bottom support?

    Hello all, I have been trying to model a truss. I have two bottom support, it can be fully fixed or partially fixed and I have two cable connection at the top. But this cable member should not take any compression, since I have Wind suction in that…

  • tension only property for bracing.

    Dear sir, In my attached model I have given the tension only property to vertical bracing . But why this bracing is failing due to compression forces .there should be only tension forces in the bracing. auditorium FINAL ADD BR3 TRUSS STRT INCREASEN…

  • Compression Code Check Error on Tension Only Member

    Hi all, I am having some real problems with a piperack structure where I am looking to specify tension-only members. The members I specify as 'member tension' still fail under the code check (Cl. 6.1 of NZS 3404) which is a compression design check…

  • Double bay Braced Frame loads not equal

    Hello, I have several double bay braced frames in the building. The diagonals are 16-ga and 18-ga CFS straps (tension only members), while the end posts are HSS 6x6. I did not model a collector beam as I have a rigid diaphragm which will be provided…

  • 'Tension Only' braces with 'Perform Analysis + Change' command analysis taking unreasonably long time to finish

    I am designing a partially cladded building with Tension Only braces. I have put Perform Analysis + Change command after each Seismic case as i wish to do IBC/UBC load generation. I have figured that the simple analysis is taking unreasonably long to…

  • Compression Forces in Tension Only Members

    Why is my result showing compression forces for Tension Only members? I am using REPEAT LOAD command instead of LOAD COMB. STAAD SPACE START JOB INFORMATION ENGINEER DATE 07-Apr-17 END JOB INFORMATION INPUT WIDTH 79 UNIT FEET KIP JOINT COORDINATES…

  • RE: Compression-only spring

    Yes you need to define the springs first and then assign the compression only attribute to it. If you are defining spring supports using FIXED BUT support option, you may follow the sample input below SUPPORTS … 1 TO 10 FIXED BUT KFY 1000 SPRING…

  • 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…
