HELLO EVERYONE, I WANT TO calculate the required torque for the pre-tension joints, i don't have much experience in this so i hope to find a help in this regard

Dear Gents, i have simple structures .and I want to design the moment connections between beams and columns based on aisc design manual 13 th ,because i don't have the end forces for the members , so i will use a percentage from the capacity , 1-what is the accepted percentage and its...

thread507-187196 can i use checkered plate to provide lateral-torsional bracing for the top flange of a steel beam?

thanks a lot "msboobathi" But i asked this question to complete my excel sheet for base plate design , the missing case in my excel is what i asked in my question and i try to find out the right way to calculate it manually to update my excel sheet

Thanks for your response but can you provide more illustration for your point

Dear Experts, i have one question about design of base plates which affected by uplift force and large moment , i want to know how to determine the bearing length at bearing interface ,i didn't find any reference for these type of plates. and i don't think that equation (3.4.3 in AISC design...

thanks a lot for your kind response, i asked my question because some times when i check drift from show tables>>>show drift i got non-logical answers for drift from etabs specially when i have extension of some columns in roof floor. i will check this method that you mention in your answer . thanks

Dear experts, i want to know how to check drift results using dynamic analysis ( response spectrum analysis ) , the traditional method that going to show tables in etabs and select show drift then see the drift in RSA in x or y direction will not work because (as i think ) etabs calculates...

very helpful replies ,, thanks all for your kind response

hi guys, i seems logic that using stiffeners in base plate will decreasing the base plate thickness ,however i can't find any reference or guide to calculate the stiffener effects, aisc design guide for base plate shows the rigid cantilever method for base plate design without stiffeners ...

thanks for sharing the solution with others ....good manners

Dear experts, I am using sap2000 v18 in design steel according to aisc 360-10 and as code required for all load combinations we must perform second order analysis including p delta effect , and the problem coming here sap is taking very long time during analysis, I want to know if there is...

thanks a lot[smile] IDS for your help

thanks guys for your response :) , but what i mean is link text box in excel sheet to specific cell in the same sheet,because i have complicated geometry in the excel sheet and i intend to but the text box at each side of that shape so the user can easily write the value without any confusion...

dear experts , i want to link text box with cell in order to make the cell read the numerical values from the text box to use this value in the sheet equations, thanks in advance

thanks a lot guys for your helpful replies i am in ksa

Dear experts, hi every one ,i don't have much experience in production of steel members ,so i have some questions for experts here, first, what is the max thickness that can be accepted to make cold formed steel members like (C -channels .Z channels) 2-for hollow square sections with small...

Dear experts , I am confused when I use chs, shs & RHS SECTIONS with small thickness (less than 4mm) such as chs 48.3x2.6 and similar ones my question is ,should I use AISE DESIGN CODE and consider it as cold formed profiles or use aisc THANKS IN ADVANCE

Dear Jatfuentes, thanks a lot for your kind answer , I agree with you in all your points ,I always do this when I using staad pro. put I don't have big experience in sap2000 again thx alot

hi every one, I have to check sap model for truss members with span 42 meters, I have two questions: 1- I want to ask about design parameters, in the model that I have all design parameters are program calculated "the designer didn't make design over right for any thing" is this right?!! 2-...
