Description:Chopra After revising and supplementing the new research results on the basis of the first edition, the professor gave a systematic and comprehensive exposition of the basic knowledge and basic theory of structural dynamics. The content is simple and easy to understand, step by step. While systematically introducing the basic theoretical knowledge, the professor closely combined with the practice of seismic engineering Some important structural dynamics problems in engineering application and even seismic design code are introduced, which fully reflects the style of integrating theory with practice. The book is also equipped with a considerable number of examples, which will be of great help to master and understand structural dynamics and seismic engineering
