Question

What two things does the magnitude of the force applied at each storey of a structure due to an earthquake depend on? Describe the typical distribution of earthquake force applied to a structure.

Answer 1

two things on which the magnitude of the force applied at each storey of a structure due to an earthquake depends are:-

1:- Overall geometry of the structure

2:- Height of the structure and each storey.

Typical distribution of earthquake load on structure:-

Increase in shear in short span beams and consequently increase in axial load on columns due to earthquake. The non-uniform distribution of loads to different structural members can initiate localized failures that in turn, can compromise the structural integrity of the building, or, even trigger global collapse of the building.
