Recently, my book was published by Elsevier Publications with the title "Seismic Rehabilitation Methods for Existing Buildings" , I should mention that this is my fourth book in the field of seismic rehabilitation. I have divided the contents of this book into 6 chapters with 680 pages based on a deep understanding of the concepts. I have also tried to present the content with using pictures, charts, info_graphics and practical examples so that the reader can use this book to do a seismic rehabilitation project. My goal in writing this book is to help those who are interested in becoming a professional seismic rehabilitation engineer. In the following, I will provide the link of the book on the publishing site for more information. I will be very happy if you let me know your comments.
