hi I model sandwiched buckling-restrained brace in abqus But I have several problems 1- how to apply The cyclic loading and buckling together in this example ? 2- Why do not stress in analysis buckling? 3- how to Define interaction Between the concrete , bolt , core and......? 4- Buckling of...

hi every body I model a brb(Buckling restrained brace) in Abaqus but my question is How to put concrete in a brb or How do I define the concrete inside the brb that work together? thankshttp://files.engineering.com/getfile.aspx?folder=00876a7f-59a7-4018-9de4-66b7a68dbfaf&file=aaaaa.jpg

Why will not anyone answer me?[sad][sad][ponder]

Hi I have a question about the connection beam-to-column of the two-dimensional how to joint (pin) of connection beam to the column ? and then apply cyclic displacement. thanks

hi i want to define define equiv strees and equiv plastic strain for steel. Where to get the values of Eqiuv stress and Equiv plastic strain? thanks

hi all freind , To reach the buckling behavior of the X-bracing system in cyclic loading , how it should be define steel behavior model in abaqus? Behavioral model is applied to the definition of the material or analysis step? In fact I want to get hysteresis loops for X-bracing system. thanks

hi 6 cycle or 4 cycle and..of loading relate to ghraf-1 and is displacement controlled loading. Drift is the deflection of the wall at story (i) minus the deflection of the wall at story (i-1), divided by the height of the wall at story i. (Δi - Δi-1)/hi This is commonly expressed as a...

Hi I have a very important question about Abaqus, I wanted a quasi-static method to analyze the cross bracing(Two-dimensional). The loading protocol consisted of 6 cycles at 0.375%,0.50%, and 0.75% drift, followed by four cycles of 1% drift, and finished with two cycles of 1.5%, 2%, 3%, and 4%...

hello all user according to answer id 4699 (I get it at abaqus.custhelp.com ), I create a Calibration in Abaqus/CAE from the Model Tree (pic1) then I have a few problems : 1 - First I have to define material and then define calibrations or first define calibration and then define material...

Hello How do and in Abaqus? How design to hook up a cable to a plate? how to prestrained cables(especially sma Cable) and also increase the pretension bolts ? Thanks and Regards

Hello I wanted some Abaqus examples for Civil Engineering (Especially for the brace) Please help me thanks

Hello all Freinds I'm create a cable or bar in Abaqus6.11. I know ,I should do it with the create wire tool but How do I define a cross section of wire?[ponder] Thanks in advance. best Regards

thanks sdebock and IceBreakerSours [bigsmile][smile]

hi I'm new in this forum and I've a problem that i can't resolve. I am M.Sc.Civil engineer and I'm modleing shape memory alloys using in bracing system.I need to model nitinol in Abaqus. how can i idintify this material in Abaqus? do i have to code this model and write subtoutine in fotran or it...
