How does one obtain design strength of concrete = 0.45fck as given in IS456:2000??? Here is the explanation: In india, we test concrete cubes to determine 28-days characteristic strength of concrete, which is depicted by “fck” However, we all know that, if we cast cylinder from the same concrete mix,…

At cold joints between columns or walls and footings
At cold joints between columns or walls and footings (especially for systems resisting lateral forces ) , ACI code requires to check horizontal force transfer ! At design stage , we are assuming monolithic concrete but in reality cold joints will occur . Cold joints may reduce shear capacity for…
I don’t understand why the curriculum/syllabus at engineering colleges is not even close to the requirements of the industry/Market?
I don’t understand why the curriculum/syllabus at engineering colleges is not even close to the requirements of the industry/Market? A simple example. We see buildings built in our area/locality almost every month. Due to less available of land, many buildings have common sides or restrictions of not exceeding their property…
Why stiffness modifier value is higher for column than beam?
The pattern and extent of cracks will vary substantially from structure to structures and members to members even in a similar structure. It is very difficult to assign the unique values of the stiffness modifiers for different members. The values which are suggested in the code are based on the…
