  • Truss model correction

    Can someone look at my model as tell if i have designed the truss model correctly. Truss Pipe no column.std

  • Truss

    Does the area of steel always remains less for a truss model than I beam to support a structure.

  • Truss modelling issues.

    Hi, I am practicing Staad pro and having issues with truss modelling. i don't know if my method is right for analysis and design of truss model. could someone tell me what is a general procedure for designing a circular steel frame shade of 35m supported…

  • Can someone please correct stiffness issues in this space truss model?

    Code is as follows - STAAD SPACE START JOB INFORMATION ENGINEER DATE 28-Aug-18 END JOB INFORMATION INPUT WIDTH 79 UNIT FEET POUND JOINT COORDINATES 1 -3.375 0 0; 2 -2.958 0 0; 3 -1.125 0 0; 4 -0.875 -1.574 0; 5 -0.29167 -1.574 0; 6 0 0 0; 7 1.667…

  • Zero Stiffness - Wood Truss Model

    Hello, I am new to modeling trusses and I'm attempting to model a wood queen post truss and have just started with the self weight of the truss but I get 13 warnings when I run the model which say: *WARNING- ZERO STIFFNESS IN DIRECTION 2 AT JOINT 3…

  • Is this Truss structure been analysed correctly, please comment on the member release and support fixity and bracing.

    Please find the truss shed file attached for the consideration as per the requirements and to remove instabilities and excessive deflection I have put redundant bracing and supports made fixed and some members chnaged from truss member to beam. …

  • RE: Warning message-"The member is not a Truss member"

    The design as per IS:802 is carried out for axial load only and so when designing the members, the software is expecting only axial forces to be present in the members, which is what happens when these are specified as TRUSS members. If you have not declared…

  • RE: RAM Modeler

    You'll find some tips here: RAMSS Truss Modeling And Design Note, for complex shaped trusses, RAM Structural System won't work. We recommend STAAD.pro or Ram Elements for those cases.

  • RE: Truss member of STAAD and the instability problems

    Fiona: There are a couple of nodes at the intersection of the long braces which should be merged. From what you described, it would be more appropriate to release the moments at the ends of the long braces rather than specifying these as TRUSSes. The…

  • RE: Modeling Bowstring Trusses

    Modeling trusses in RAM SS is fairly limited. If you have a story for the top and a story for the bottom and model the verticals as columns you can get close. Here are some other tips and warnings: RAMSS Truss Modeling And Design

  • Vertical and roof Truss design

    Hi, I really need help. I am trying to design an open warehouse made of steel truss roof and column. I keep on getting joint instability on one of my support. I don't know if what I did was right in my modelling process. Should I separate the design…

  • RE: Why compression force in tension members and why tension force in compression members developed?

    Here is how the generated member forces can be explained. If you look at the axial forces in the inclined braces, these are developing significant axial tension ( specially I am referring to the extreme 3 on each side ). The amount of axial tension…

  • RE: How can I design railway bridge gusset plates in LIMCON/ RAM or any other software of Bentley?

    We don't have truss connections in Ram Connection yet. In Limcon the KT Gusset Plate Connection type could be used form some configurations where you have three members connecting to the chord member.

  • RE: Member Release

    Yes, if you have two or more members that are connected to the same node, and if those members are not released, then the joint is like a fully fixed or welded joint and moments can occur there regardless of the support condition. You should probably…

  • why does the top and bottom chord fail? what should i do to make the columns to pass?

  • Roof Loadings

    Hi guys, I wanna know how do I put wind loads on my roof or rather place any loadings on it do I place earthquake loads also? Thank you! Also is it ok to use Structure Wizard for creating a truss then place it on my structure? I'm really new…

  • Design of Truss and Structure

    Hello! I'm a CE student and im trying to design a structure made up of steel. I would like to know what connection do I actually use for the support on trusses, and on STAAD.Pro do I place the truss on my structure or do I analyze the structure…

  • Facing Problem Regarding the Anylises of the industrial shed.

    Sir i watch your lecture on you tube. I have some problem regarding my project. I am working on some project in staad pro which was actually designed and drafted by structural Engineer . The project is the design of industrial shed. I am considering…

  • Truss Deflection DJs

    I have a question about how to set-up the design parameters to accurately check the top chord deflection of a pitched truss. The high-point of the truss occurs at the midpoint between the two support columns. For a flat truss, I would normally define…

  • lattice truss analysis

    Hello friends, I am having problem designing lattice truss in staad. Since i am new to steel design , I want to cross check my structure and all missing parameters to be considered as per IS 800. thank you in advance Lattice Structure.std

  • Truss Design failing members

    I need to design truss steel structure 50x80 mts as per IS code. Solar panel is mounted on truss structure acting as a roof. I have analysed the structure. Is this correct way ? Lot of members fail. Please point out the mistake have done

  • RE: Truss member not being tensioned

    First thing to do is to change the structure type from TRUSS to PLANE as shown next. STAAD PLANE *STAAD TRUSS Secondly your member 8 is not split at the node 19 and so there is no connection between members 8, 20 and 3. You need to make these intersect…

  • RE: Truss Design Instability Issue At Joint

    I would think that your top and bottom chord members would be continuous members and would be subjected to bending. So you should not declare these or the vertical columns as TRUSS members. Instead you should declare the verticals and inclined braces…

  • 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…
