Question

Inertia forces generated by the earthquake shakings primarily develop at the floor of the building.

(a) True

(b) False

I got this question by my college professor while I was bunking the class.

I want to ask this question from Earthquake Resistant R.C. Buildings in section Earthquake Resistant Buildings of Construction & Building Materials

Answer 1

Correct answer is (a) True

To explain: Inertia forces generated by the earthquake shakings primarily develop at the floor of the building. This is because most of the mass of the building is present at the floor levels. These inertia forces travel downwards through beams and slabs to walls and columns and then to the foundations from where they are finally dispersed to the ground.
