Effect of Higher Modes on the Design of Structures that Resist Earthquakes

Abstract

Seismic waves carry the earthquake's kinetic energy to the structure, where it is then transferred into vibrational motion through the foundations. The reaction acceleration for extremely short time period (high frequency) structures will be close to the maximum acceleration felt by the ground. Long-lasting buildings can take use of the system's adaptability; the mass won't budge no matter how much the earth shifts underneath it, and the relative deformation will be just as large. Examine the impact of higher modes on earthquake-proof building design in this research.
