    cyclic loading and buckling sandwiched buckling-restrained brace?????

    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...

    How to put concrete in a brb (Buckling restrained brace) in abaqus?

    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

    problem to define steel for X-bracing system in abaqus

    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

    help How to analyze (quasi-static method) a cross bracing in Abaqus....

    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...

    help How to analyze (quasi-static method) a cross bracing in Abaqus....

    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%...
