What is Reinforcement Ratio | Example Solved

This video shows what is reinforcement ratio. Reinforcement ratio can be defined as the ratio of area of steel to the area of concrete. It has no units because its only the ratio of areas. Reinforcement ratio shows how much steel are used in any structural members.
Reinforcement ratio have different ranges for different structural members. Some of these ranges are as,
Reinforcement ratio for beam is 1-2%
Reinforcement ratio for column is 1-8%
Reinforcement ratio for footing is 0.8-1%
Reinforcement ratio for slab is 1%

#Reinforcement

[@kumarkishor757]

please tell me
According to the different reinforcement ratios, which types of concrete beams
can be divided into?

[@missengineer3747]

Does "d" (effective depth) should be taken at the mid of the reinforcement or not? Please verify. Thanks.

[@palak6513]

Sir can u explain in the one way slab what is the minimum requirement in spacing for numaricals purpose what is the correct velue of spacing in reenforcement....,.....?

[@asfarnasir]

Salam sir, can you please confirm if the "d" taken here is from top to bottom or from top to middle of reinforcement?

[@phyohtetkoko929]

Thanks For Teaching Sir

[@civilengineering94]

It's my pleasure

[@abdurrahim3605]

Thanks a lot.
Complete

Welcome

[@engineermoon]

Thnks my dear sir

[@naseeruddin4994]

it's really helpful

[@civilengineering94]

Glad it helped

[@Hasib481]

want surveying video like bearing

[@abdulkadersagar5412]

sir,
is it satisfied ACI code?
or, IS?
or both?
plz.............
plz..........

[@civilengineering94]

According to ACI

[@abdulkadersagar5412]

tnx a lot

[@deepaky100]

Nice Sir

[@civilengineering94]

Thanks

[@user-ct9xl6td1k]

Sir please abload vedio strong column week beam and short column and long column effect

[@civilengineering94]

Okay I will upload soon

[@user-ct9xl6td1k]

Sir your vedio is very useful

[@sheikhkais4140]

Sir , explain 3.16 where he comes from.
Plz solve this

[@civilengineering94]

Its the area of steel used here in this cross section of beam, We know area of #8 bar is 0.79 and we have 4 number of bars in cross section so total area will be 4*0.79 = 3.16 inches square. Hope you understand

[@sheikhkais4140]

Area of 8 bar ?
Explain sir (0.79)
Solve this sir

[@abdulkadersagar5412]

((Pi)/(4))*(8/8)^(2) where,pi=3.1416

[@KummaraSivaPrasadPHD]

how you got 0.79 in 2 as Area of steel

[@civilengineering94]

You can get from the area of circle formula: Area = pi x r ^2

[@naqiengineer6042]

sirji is this ACI?

[@civilengineering94]

yes

[@naqiengineer6042]

more topic about ACI sirji, i am your number 1 follower here in philippines, salam..

[@anbusanthosh6887]

Ur video is not visible ,kindly avoid subtitles

[@letslearntv2692]

How u have taken 0.79 yar? No explantion for that?

[@civilengineering94]

Area of #8 bar is 0.79in^2

[@kamalnahak9720]

I think the area of steel of that coloum

[@kamalnahak9720]

1st u have to identify the area of steel of tha all steel bar of that coloumn

[@nageshwarsharma9599]

Please say in H.ìndi
