How to Protect Concrete Homes and Offices from Earthquake damage? Introducing Ductile Detailling

How can one protect their homes and properties constructed with concrete from damage due to earthquakes?
An engineered building vis - a - vis an un-engineered building makes the difference.

Check out the Table of Contents Below
Construct your buildings to minimize damage due to an earthquake. Engineered concrete buildings behave better than non-engineered ones. Join us in this video as we go through some important aspects of constructing concrete buildings that will help save lives - Maybe yours. We also see the potential of an earthquake occurring in different parts of India and different configurations of buildings that are shared.
This series targets educating non-civil engineers, but it is certain that civil engineering and structural engineering students will also benefit.

Concrete is a brittle material - one that can fail suddenly like a wooden ruler, without warning. However, if we have a steel ruler, it will bend significantly before failing. This is ductile behaviour and accommodates large deformation before eventually failing. When such behaviour is exhibited by a building it is desirable because it not only can absorb a lot of energy, it also gives adequate warning to occupants that there is a potential to collapse.
The good part of an engineered structure is we can make it behave the way we want them to by varying mass, stiffness and damping present in the structural system. While a non-structural engineer does not really need to worry about the calculation, awareness of the different requirements to be safe applies to all.

Do share with those who are considering constructing their own homes or offices.
