✨Creep Deflections✨
▪️Concrete Creep is the deformation of structure under sustained load.
▪️The strain due to creep is much larger than the elastic stain.
▪️When the load is removed , the strain due to creep will not be removed completely.
▪️ Basically, long term pressure or stress on concrete can make change in shape.
▪️This deformation usually occurs in the direction the force is being applied like a concrete column getting more compressed, or a beam bending.
▪️Creep does not necessarily cause concrete to fail or break apart.
@civilmaniaa
📌Effects of creep
1) In reinforced concrete beams, creep increases the deflection with time
2) In eccentrically loaded columns, creep increases the deflection and can lead to buckling.
📌As per IS 456-2000
Creep can be calculated by using Formula
🔗Deflection = wl^4 / 384Ece I
where , Ece= modified young’s modulus of concrete= Ec/(1 + θ )
θ=1.6 (creep coefficient for 28 days age at loading)
=1.1 (creep coefficient for one year age at loading)

As per the Reply of Railway minister Shri Piyush Goel in Loksabha , UPSC will conduct separate entrance exam for IRMS .Railway will neither take from CSE nor from ESE .
There will be 5 categories in IRMS recruitment .
1. Civil Engg
2. Mechanical Engg
3.Electrical Engg
4. Electronics Engg
5.Non Engg
Prelims will be common for all and for mains paper candidate will choose their respective paper / stream .
For recruitment of IRMS ,Notification will be made by UPSC .
