Dear Friends,
I am modelling a steel - concrete composite box girder (single box) by using ABAQUS.
I simulated for simply - supported beam with an applied concentrated load in a mid-span.
I can plot applied load - deflection curve for my model; however, I do not know how to plot applied shear - deflection curve.
Please show me how to plot it
Thank you so much
hi
you said you applied concentrated load at mid-span and you could plot applied shear-deflection curve. my question is which applied shear you want to plot and where did you apply. waiting your response in order to advise you .
Hi
as I said, I am modelling steel box, therefore I would like to find ultimate shear strength of the steel webs. I mean, when I applied load, I can plot the applied load - displacement curve by using model Riks in abaqus. However, I do not know how to obtain ultimate shear strength or plot applied shear - deflection curve
please show me how to obtain it
thank you
hi
let us say we need to integrate the shear stress along the height of web at mid span
so you may plot the shear stress distribution along a path you defined along each web at the mid-span. then integrate this distribution to obtain the shear force/each web.
I tried to answer your question according to my understanding. I hope it helps you.
Hi,
I am sorry because I do not understand your answer.
I am modelling steel box using nonlinear inelastic analysis, therefore, I think we can not obtain the shear force by this way.
By the way, in my case, the failure model caused by flexure, so I think we just obtain flexure resistance and we can not obtain the shear resistance unless the failure model caused by shear force. Am I right?
I am sorry because of my question confusion
yes you are right. your question made me confused.
to get the shear force-shear displacement curve, you need to develope new model for that (pure shear including buclinkg for the web only). if you still need it i can help you but it needs sofisticated model.
