I am iranian i should say you are so great man

[@kyroloszarzor4649]

thank you for all your effort and hope to continue and present advanced course of idea

[@puttattjayarajan1199]

The next level consists of seismic qualification of different types of joints using IDEA statica considering component methods, ec3 ,ec8 & aisc prescriptions. Have nice day

The tensions (Mpa) shown in IdeaStatica analysis not vector like those in Sap2000 - No + or - signs?

I need your help regarding idea statica model

[@Anne-tq5zq]

Everything is awesome in Statica , but how do we detail our Final drawing..?? I didn't see any way to detail for finalized drawing... That export to DSF file is super trash, it does export to CAD file but very little info is detailed. Main Problem I'm facing right now is , After the successful design of Connection, How the we export to Detail Drawing???? if there exist any way or require additional software please explain.

perfect, thanks a lot.

[@dwigaluhayu9216]

thank you sir... this is helping me a lot.. sir, can you make a tutorial for the gusset connection on the truss bridge?

[@nishantgoel2409]

Sir as we can see the stress in stiffening plate is equal to the Yeild capacity of the plate i.e 275mpa. So does that mean that we need to change the thickness of the plate.?

[@puttattjayarajan1199]

This means that the material has reached its limiting value fy. The acceptance of this stress level can be made by looking into the plastic strains developed in the component. If the strains are small (

pls what is the meaning for ( set bearing command) and how does it effect the results ? because when i design connection and assign one member to be ( set bearing contious ) the result analysis will differ if i change the set bearing to other member thank you

Hello Taha, This is an interesting question.!!! In analyzing a structure in any software , we always "assign" the correct supports to ensure that the structure is stable and that the calculations do converge. IDEA Statica , which is essentially an FEM based software for the connection design do the same thing through set bearing command. The members which are set as "bearing" do have supports on its ends and thereby you will not be able to apply any loads on these ends. The members "set as bearing" shall be judiciously chosen by the designer based on his objective. The analysis results are obviously affected by the choice of "set bearing " member..!!! Also note that IDEA statica has two options for analysis (i) simple: in which we mention one member as "set bearing". (ii)Advanced with one end bearing and an equilibrium check done using the ribbon loads in equilibrium If you are importing the forces in various members for a given load case, the equilibrium is already confirmed and no further equilibrium check need to be performed by IDEA Statica. Practice makes you perfect......true for IDEA Statica too. Further you should also have sufficient technical base to verify that the results by IDEA statica are reasonable and this also enables you to track the mistakes in modelling Hope that this answers your queries....please share the vides with your group as well. Have a nice day

@@puttattjayarajan1199 thanks Puttatt for your swift answer :) can I assume the truss top rafter ( the main member) which carries out of-plane purlins to be supported ( bearing) as the purlins are covered with panel sheets which give purlins some restrains ?

[@puttattjayarajan1199]

@@anastaha2438 Hello Taha.. There seems to be some kind of misunderstanding regarding what to be considered as a bearing member.. As a simple explanation, consider bottom joint of a truss consisting of four members two each horizontal and diagonal members . If you are interested only in verifying the connections for diagonal members , the horizontal members can be considered as bearing. On the other hand if you are interested in the stress distribution in horizontal members and adequacy of their connections, you can keep diagonals as bearing. That is, I am repeating , which member to be considered as bearing depends only on the objective of your analysis. Please remember that the joint can also be checked without any bearing members wherein you will apply loads on all members meeting at a joint and press the ribbon "equilibrium check" before design. If the member forces correspond to a single load case (not envelope) , the equilibrium check is always guaranteed, You don't consider restraints etc as specified in your query for consideration of bearing members. Such consideration are used only in obtaining effective length of truss members. Hope this will clarify the matter further.

[@anastaha2438]

Thank you so much

[@anastaha2438]

Dear Puttatt, Can u pls clarify the actual end member and the continuous member for load cases? Examp;le when there is a continuous column and an end beam, when I need to enter the load and stress values for the column, i assign the bearing for the beam . and when i need to enter the load and stress values for the beam , i assign the bearing for the column Now, does the program take into consideration while analysis that all the loads for both column and beam are entered , especially in equilibrium check?
