Briefly describe the principles of base isolation and energy dissipation structures, and what is the difference between them and general seismic structures?

The concept of base isolation was first put forward by Japanese scholar He Zang in 188 1. He thought that several layers of logs should be laid crisscross on the foundation, and then concrete foundation should be built on the logs to reduce the energy transmitted by the earthquake. In 2009, J.A. Calante Lentz of the United States proposed another seismic isolation scheme, that is, building on the foundation and concrete foundation.
