Determination of effect of earthquake on building

Determination of effect of earthquake on building

The effect of an earthquake on a building is determined by the :

• Time histories of the three ground motion parameters
• Ground acceralation (ag)
• Velocity (vg)
• Displacement(dg)

Ground motion parameters depends on:

• Distance
• Direction
• Soil characteristics (layer thickness, shear wave velocity)
• Depth and
• Mechanism of the fault zone in the earth crust

As for the response of a building  to the ground motion, it depends on structural characteristics (eigenfrequency, type of structure, ductility etc.)
