Modeling Damaged RC Frame and Retrofitting

Post by Mohammad_Vali »

Dear Sir/Mad
Hello
I want to:
First: apply strong earthquake records to a RC frame; therefore, plasticity and damage extends in the elements.
then Second: use FRP on the damaged elements and again apply strong earthquake records.
Can I use Seismostruct to do this process?

Dear Mohammad_Vali,

In SeismoStruct's Post-Processor, the elements that have exceeded their capacity at a particular code-based check (or the elements that reach a particular performance criterion) may be visualised by choosing the Code-based Checks option (or Performance Criteria option) and selecting if the plastic hinges/ damage locations will be shown, and whether these elements will be distinguished through colours and/or damaged textures.

Further, FRP wraps may be assigned to columns through the FRP Wrapping module. Users may select the FRP sheet from a list of the most commonly used products found in the market, or alternatively introduce user-defined values.

Finally, there is a one month trial version available in https://seismosoft.com/products/seismostruct/ so that you could check if the program covers your modelling requirements.

Dear Zoi Gronti
Thanks for you reply.
Really my question is this:
I have run my model and the members have damaged.
Really my question is this:
BY WHICH WAY I CAN USE (OR MAYBE I CAN MODEL) THE DAMAGED MEMBERS (IN ORDER TO RETROFIT BY FRP...)?

You may use time-dependent members to simulate the strengthening interventions AFTER the sustained damage by the seismic event, however this cannot be applied for FRP wraps. All the same, note that FRP wraps should NOT be applied directly to damaged members and the repair of the sections should be done prior to their application.

In SeismoStruct strengthening on the member level can be modelled through FRP wrapping and RC jackets. On the global level new shear walls, steel braces or base isolation can be employed.
