Carbon Fiber Reinforced Polymer for Concrete beam

[@abbasj-d6951]

thank you dr...

[@msc.str.engineermohammedad4269]

please sir , would you mind if teach me how to insert the properties of CFRP if it was a reinforcing bars not lamina ?? knowing that its ultimate tensile strength 2174 Mpa and its corresponding strain is 0.01 and used under impact load . thank you so much for you valuable video and instructions ♥

[@vandangtran6454]

Hi, a reinforcing bar is considered a normal steel bar. so, make the part in 3D with "wire" shape; element type: truss; interaction/constraint/embedded region (interaction between steel bars and concrete beam). that was shown in the previous videos about steel-concrete beam

[@lostkid_007]

@@vandangtran6454 ... is it possible to model the reinforcements as solid elements ?? if yes then what properties I should use. Any reference would be helpful.

[@vandangtran6454]

@@lostkid_007 Hi, yes, it is strongly possible if you want to do that. you should define the properties of the steel (reinforcement), then you have to simulate the surface contact between the reinforcement and the concrete. For the latter, I often used cohesive surface contact, like in this video: kzbin.info/www/bejne/hma2pIeDhNqKmLs

Hi Mr Van Dang Tran, could you teach on modeling CFRP grids as a form of reinforcement embedded in the surface of concrete slab?

[@vandangtran6454]

Hi, in this video I showed exactly what you want. except that you want a slab instead of a beam. Tell me is that it

How to apply the prestress to the CFRP that you have attached to the bottom surface...I have gone through the topics which had prestress CFRP plates ..can you let me know sir how to do that..

[@vandangtran6454]

Hi, it is not complicated to do that. so, you are in Load/Predifined Field Manager/Create/ (step: initial; Category: Machanical; Type: Stress)/ choose your CFRP plates, and integrate the value of prestress. Regards!

[@domingochangk9987]

is there videos works of ultra-high performance concrete beams prestressed with external CFRP tendons please? I need it.

[@vandangtran6454]

Hi, the concrete i used in the model is a normal concrete.

Sir , can you please provide gfrp material properties

Thank

Sir can we provide CFRP using ETABS software

sorry! i'am not a specialist on ETABS

How to import line geometry from autocad to abaqus ? For my case the section depth varying and preparing it in autocad is easy but I am not able to import the line elements into abaqus. Please let me know a way forward,

[@vandangtran6454]

if it is not complicated, you can draw directly in abaqus. You can see on this video also: kzbin.info/www/bejne/Z4SmqoOsostml9U

How to apply grout in RCC Beam? Plz make a video

[@ym9849]

why do you want to add grout? do you want to add the CFRP Model?!

[@vandangtran6454]

Hi, can you send me any more infor. i don't truly understand your question. if not, you do exactly like this video but instead of the fiber carbon, it's your grout

[@constructionsite8407]

@@vandangtran6454 It means, applying grout to the cracked area of the beam.

Please let me know the Name of this program ?

[@logainalhelwani1937]

Hello sir, is there a reference or code for the cfrp characteristics that you entered in the program? because I want to put a reference at the end of my master's thesis for the cfrp inputs that I relied on from this video😢

[@vandangtran6454]

Hi, sorry i did not save the reference. Just an example !

[@rukminb412]

In my syllabus there is the latest assignment related to Abaqus model in which I have to make a model of 'retrofitted geopolymer beam using CFRP mats' using the same dimension as mentioned in the research paper. Could you please help me with this? I am attaching the research paper from which my professor has asked to do so. Sir I have sent u mail with details..l look forward for your reply

Sir, I'am modelling slab strengthened with CFRP strips on Abaqus, but the interface between concrete and CFRP is modelled as cohesive zone model... So can you please help me out on how to model as CZM??? Please do reply .....

[@vandangtran6454]

In this video below, i have used the CZM as surface-to-surface interaction without defining the material of glue kzbin.info/www/bejne/rmfIXp6Fe812Zq8 if you have more things, contact me by email
