Analysis of Vertical Beams for Piles and Sheet Piles Subjected to Lateral Loads By Takeshi Ishiguro and Kunio Takahashi Sankaido After purchasing, I only read the necessary pages and stored it in a case in a dark place for over 30 years. The case has discoloration, stains, and dirt due to aging. The book itself has no noticeable scratches or stains. Please purchase if you understand that this is a used book that has been stored at home for over 30 years. Please inquire before purchasing if you have any concerns. Please read the profile before purchasing.
