Types of Cracks in Beam

[@19zacke]

Dear Sir, I have perpendicular/ vertical cracks near columns. The beam length is of 15 feet and cracks are noticeable at the bottom of beam which is 3 feet away from the column. Cracks are type of hairline crack. Can you please advise, thank you so much in advance!!

[@viswamvaranasi2770]

Thanks for explaining the types of cracks and places of occurance. But what is the solution to strengthen at such places of cracks? In a recent incident I did observe that the 2 main rods of the beam were cut off Abou 1.5 feet frm the column.(To mount an A.C.installatio hole was dilled.due to that the main rods were cut off) Now how to safe gaurd the beam and eventually the structure. The residential building is G+2. can you pl .give solution?

excellent bro...past 3 days i am seeing ur videos continously...still its not end ...that much stuff u gave for us.. thanks a lot....

#Vino_dha Thanks for being on my channel :)

Your audio is not clear enough to listen properly. Plz. do the needful at your end. Thanks.

Hi sir newly iam construction my home slab and beams done by Reda mixed concrete length beams horizontal crack slab total crack and water leakage problem 19 days complete sir first day to right now complete water leakage problem sir

[@pankajtembhare9529]

great sir.....now clear all doubt...tell me one thing sir...principal stresses are generated in case of bending...

[@masoomjanalikhel9705]

Hi Can you please explain the reasons of such cracks and the ways to avoid or overcome such cracks?

[@thollyvezi1127]

Concrete is strong in compression but weaker in tension. Thats why you must use reinforcement Steel to prevent cracks

[@alimran3394]

Sir,Can u just make your pronunciation a little bit clear. then it would be easy for us to understand ur lecture

[@civilengineering94]

ok Shafe

[@ForensicCats]

7:10 your shear crack ''lines'' are in the opposite direction ... note, you did put it correctly in your thumbnail... But, I do videos also and we all make mistakes when doing our content... we have to educate and video record and narrate... (mistakes a bound to happen). Thank you for posting.

[@deltacreations6247]

Why shear cracks are like inclined and why flexural are straight ?

[@robertpbaqueroholguin9947]

Hello sir, very good video. I think there is a slight mistake. When shear stress is negative the cracks are in 45 degrees but in the other direction, correct me if im wrong.

[@mariamabdelmonem9960]

He already drew shear stresses in 45 degree! So if he mistaked sayin it ..where is Ur eyes Robert ?

[@MushtaqAhmad-vy3tc]

Sir the flexural shear crack start from the bottom or from the side of beam.please

[@civilengineering94]

side of the beam

what is elastic shortening? how it will be taken care in the design?

[@DarvaishBandah]

what are the reasons for these cracks? elaborate it, please Sir

[@shaik.nagursharief990]

Very good explanation like crystal

[@gregoryharington6686]

Nicely done..

[@civilengineering94]

Thank you so much

Thankyou very much sir. I was crying for this basic understanding.

Good to know #Tripta

Thank you sir.

Most welcome

Reason for column crack??

[@toshagrawal4629]

Hii sr i have a doubt can you please send a way to contact you i m a big fan of your work

[@civilengineering94]

Yes, please write it here #Tosh Agrawal, Thank you

[@toshagrawal4629]

Hii when lets assume in T section which is under reinforced depth of N.A. from extreme compression fiber is 50 mm (maximum compresive strain is 0.0035) and depth of centre of tension reinforcement from NA is 500 mm(thus by compatibility of strain tensile strain will be 10 times maximum compresive strain) is that much strain allowed?

[@chesslab1]

Nicely Explained.

Hi Engineer, I always check your channel. I really appreciate your efforts. Your channel is quite useful. Keep up the good work MAN! I've requested before, if you could share basics about welding, supervision of welding and all essential required for an engineer to know about welding. Thanks Again

[@civilengineering94]

Thanks dear Morteza, I will try.

[@saritagurung7368]

@@civilengineering94 sir I need ur help

[@arvindsaini2667]

Why the tensile cracks are vertical

[@civilengineering94]

Because the only way for beam to crack is the vertical way.

Inspector Clouseau LOL Your accent is too heavy and when I look at the CC it also can't figure out what you are saying. Maybe you want to include your transcription so we can understand you?
