hi
i have a question
for a concrete beam which was not designed in proper way for shear (shear deficiencies )
should the stirrups reach its ultimate yield strength ( fy) before the longitudinal steel?
or shear failure happens only when concrete becomes cracked very much
hi all,
when we use the cfrp Sheets for shear strengthening for concrete beams.....the beam will handle more load......but would that delay the longitudinal steel yielding or not.....i tried to analysis a concrete beam with and without cfrp.....but the longitudinal steel yielded at the same...
how can i define the failure load of a concrete beam?
is it when the program stop
or when the steel reach fy
or when the strain in concrete becomes 0.003?
and how can i know is it a shear failure or a flexure failure?
hi all
i am using solid185 to model frp
but how can i enter the failure criteria "tsai-wu" for this element?
what parameters should i enter.....and should i enter the failure criteria before or after i do the analyze .
thanks
hi all
does any on know how to apply (time - accelerator ) curve in ansys
i know this is transient analysis , but how to introduction this curve for ansys, and then apply it into the structure base.
thanks
hi,
I made a model for concrete beam , and apply the load as load steps, and then I made static non-linear analysis , but.....how con i define the critical or the ultimate load that the concrete beam can stand before collapse and how can I now the results for each load step? how can I draw the...
hi
i am modeling a reinforced concrete beam in ansys, but should i only applying the load or should i make a load steps?
and if i must make a load steps......how to do it?
hi,
i am modeling a concrete beam and i want to connect steel nodes with concrete nodes , first i create a concrete element then i copy it to create the beam , but how can i add the steel and then use combin39.....any help
