Features: If the nature and magnitude of future earthquakes at the construction site could be known in advance, the difficulties of seismic design would almost be eliminated. However, even with the use of the new plate tectonic theory, the necessary information for detailed building structural design cannot be obtained. As mentioned above, the allowable plastic deformation of the structural members in a ductile resistance-type building structure is very complex under seismic action, and this response is highly influenced by the characteristics of the seismic motion. Therefore, to ensure the safety of the building, it is necessary to ensure that all structural members have sufficient strength. Seismic isolation structures utilize seismic isolation devices such as seismic isolation bearings and dampers to isolate the foundation from the superstructure. Although the deformation of the seismic isolation layer is affected by the characteristics of the seismic motion, the deformation and stress of the superstructure are greatly reduced. Even under major earthquakes, these deformations and stresses remain very small, making it feasible to design the superstructure based on stress. This book is extensive in scope, covers a wide range of content, and delves into technical details, making it smoothly translatable into Chinese. After approximately 20 years of research, based on the results obtained from design practice, a preliminary design system for seismic isolation structures has been formed. By referring to this book, we hope to design and implement better seismic isolation structures, while also promoting the development of seismic-resistant structures.
