Abstract

Examining the relation between peak horizontal ground acceleration and peak horizontal ground velocity of past earthquakes, the ratio of velocity increase to acceleration increase is small for larger motions. The reason is guessed that if the earth stiffness enters the plastic zone or the earth is destroyed at high level motion, the resistance to velocity increases. Therefore, when seismic design is formulated by considering the plastic zone of materials at high-level motion, the motion energy method using velocity is more suitable than the force method using responded acceleration.

Consideration of the Peak Horizontal Velocity

New York, New York

Examining the relation between peak horizontal ground acceleration and peak horizontal ground velocity of past earthquakes, the ratio of velocity increase to acceleration increase is small for larger motions. The reason is guessed that if the earth stiffness enters the plastic zone or the earth is destroyed at high level motion, the resistance to velocity increases. Therefore, when seismic design is formulated by considering the plastic zone of materials at high-level motion, the motion energy method using velocity is more suitable than the force method using responded acceleration.
