Hi All,

As we know that concrete properties will change during the time.

Its related to creep and shrinkage which will affect the modulus of elasticity during this the considered time which is will cause significant changes for high rise building when we check the column shortening.

In the load cases, a parameter time should be added to calculated the effect of creep. Essential to evaluate additional  deflections over time. Essential to evaluate the concept of slabs supporting walls or beam,slabs bearing elements sensitive for cracking under deflection.
