WebThe variation of ground acceleration with time recorded at a point on ground during an earthquake is called an accelerogram, Fig. 7. The nature of accelerograms may vary depending on energy released at source, type of slip at fault rupture, geology along the travel path from fault rupture to the Earth’s surface, and local soil. WebThe seismic loads on the structure during an earthquake result from inertia forces which were created by ground accelerations. The magnitude of these loads is a function of the following factors: mass of the building, the dynamic properties of the building, the intensity, duration, and frequency content of the ground motion, and soil-structure interaction.…
