FRP modelling

[fekar]

Hi
I am trying to model reinforced concrete shear walls strengthened with FRP.But, I have problems to strengthen the wall.
I would have to strengthen shear walls of the section characteristics apply?Or can create a profile and assign the FRP , it will be retrofitting.
In the section characteristics FRP jacket option does not function properly !!!
Thanks in advance for your help.

Dear fekar,

You will find a number of posts on this matter if you carry out a search on this forum. The SeismoStruct User Manual and Help System might also help you.
What do you mean by "In the section characteristics FRP jacket option does not function properly !!"?

Hi
Thank you very much z.gronti

I looked , but could not find the solution to my problem.

Exactly, I want to know , for retrofitting reinforced concrete shear wall with FRP, what to do in the application seismostruct?

Thanks in advance for your help.

Hi Fekar,

FRP wrapping in a RC member contributes in three ways: (i) increases the confinement factors, which can be included in the analysis of SeismoStruct through the special dialog box that can be opened from within the Sections module (ii) increases the shear strength and (iii) improves the lap splices through clamping. The last two effects are not automatically accounted for in SeismoStruct v7, however the shear strength will be automatically calculated in SeismoStruct 2016 that will be published in the spring of 2016.

hi

thank you for your response,

But I have an important question ?

My problem is that ,

For rehabilitation shear walls , with FRP

Can I create a rectangular hollow sections ,

Then it does give FRP material ,

And then lock the hollow section to the shear wall as a cover?

Is it possible , with this method , the shear wall rehabilitation with FRP ?

Namely , shear walls to be covered with hollow sections made ​​of FRP ,

Thanks in advance for your help.

No this is not a valid method for modelling. The main reason for this is that wheereas the FRP wrapping acts on the direction perpendicular to the axis of the element as external confinement and shear reinforcement, the hollow section that you suggest will act on the direction of the axis of the member.

Hi everybody
can anyone give me a example of FRP model?
