SHEAR FRP beam reinforcement

SHEAR FRP beam reinforcement

SHEAR FRP beam reinforcement

(OP)
hithere,

any suggestions on how to design reinforcement with FRP

i have:

r/c 25x50 cm emerging beam,
the slab thickness is 20cm
no rotations are allowed at both endings
span loading 3 t/m
beam lenght 6m

the existing reinforcement is only 50% than required

thanks

RE: SHEAR FRP beam reinforcement

can you clarify what means FRP?

RE: SHEAR FRP beam reinforcement

check out Mbrace.com  they have a design guideline for FRP and CFRP wraps.

RE: SHEAR FRP beam reinforcement

FRP stand for Fiber-Reinforced Plastic reinforcement, here aiming for repair of a structural defficiency in shear.

RE: SHEAR FRP beam reinforcement

I have heard of taking sheets of FRP and epoxying them to the face of beams, walls, etc.  The tensile strength of these sheets is tremendous, and the d you get by placing them on the face really increases your bending capacity.  There is an article in one of the recent Structural Engineer magazines about using these sheets for masonry.  I'll try to dig up the article.

RE: SHEAR FRP beam reinforcement

July 2001 issue of Structural Engineer Magazine.  However, the article is on Carbon FRP's.  Sorry.

eBook - Mastering Tolerances for Machined Parts
When making CNC machined parts, mastering tolerances can be challenging. Are general tolerances good enough? When does it make sense to call out for tighter tolerances? Do you need a better understanding of fits, datums, or GD&T? Learn about these topics and more in Xometry's new e-book. Download Now
eBook – How to Choose the Correct Corrosion Testing Method
When designing a metal component, engineers have to consider how susceptible certain alloys are to corrosion in the final product’s operating environment. In a recent study by NACE (National Association of Corrosion Engineers), it was estimated that the direct and indirect costs of corrosion in the United States is approximately 6.2% of the GDP. In 2016, that cost exceeded $1 trillion dollars for the first time. Download Now
