Relative story drift condition not met error

[arviStar]

Hello, The project that I analyzed and reported in Program 10.14, gives the error in the title in 10.17. At the same time, sufficient staff is insufficient. I throw the data and I get the same error when I get analysis in every project. Can I find out what caused the problem?[/b]

Re: RELATIVE FLOOR SHIFT CONDITION WAS NOT FAILED, ERROR Hello; The reason for your problem is that in V10.17, in systems that do not have a rigid diaphragm, relative floor drift control is performed on an element basis. Since steel flooring system is used in your project, it is considered that you do not have a floor diaphragm, for this case: 1- You can use composite flooring 2- You can choose your column beam elements from more rigid elements such as HEA or HEB 3- You can create a diaphragm effect by throwing diagonals on the floor plane as in the attached screenshot . 4- Remove your independent reinforced concrete columns that are not connected to the steel system from the system. ADL ratio before horizontal diagonals: ALO ratio after horizontal diagonals are defined: Best regards.

Re: RELATIVE FLOOR SHIFT CONDITION CANNOT BE PROVIDED, ERROR Since we are solving steel, I think we should solve it with the least cost, not by constantly increasing the cross section. The disadvantage of this program is that according to sap2000, in addition, we cross the secondary beams there, how will the manufacturing and assembly of the secondary beams be done?

Re: RELATIVE FLOOR SHIFT CONDITION NOT FAILED, ERROR Hello I think you misunderstood what I said. The subject has nothing to do with IdeStatik. If you create and solve the same model exactly in sap2000 and do the same checks, you will see the same negativities. The disadvantage of IdeStatic, as you call it, is that it automatically performs and presents the issues that are not done automatically in sap2000 and are not examined by the user. What I said in my previous message are the principles that should be applied in general for steel structures. Let's come to the application of in-plane braces: you can level the braces and place them under the secondary beams. Sample application image is attached.

Re: RELATIVE FLOOR SHIFT CONDITION WAS NOT FAILED, ERROR Hello; First of all, you need to choose the diaphragm according to how the project will be implemented in the field. If you are going to transition with metal sheet, keep it as you modeled, because metal sheets do not have a rigidity that will allow the whole system to move together. However, if concrete flooring is to be manufactured, you can convert it to concrete flooring in the field, and you will have to make your beams and columns stronger in order to exhibit the fully rigid diaphragm behavior, which will begin to see inadequacy. Relative translation boundary condition is a control of TBDY 2018 and SAP2000 does not control it automatically. If you create the model with the same support conditions, the same section, material, geometry and loads, you cannot obtain a different value in the relative offset. If you are not sure about the relative displacement, what you need to do is as follows: 1) Check the DD-2 and DD-3 values you entered on the design spectrum page from the analysis settings wizard. In the early versions of v10 2, DD-3 was not available in the wizard, the problem may occur when reading old files. Redefine this tab. 2) If you wish, transfer the model to SAP2000. Analyze. Manually control the x and y direction relative translations for whichever column's top node is moving the most. Good work.
