"This is a splendid tour of our architectural world, from pyramids to bridges, from Gothic cathedrals to skyscrapers , from huts to sports stadiums. With clarity, simplicity, and pleasure, Dr. Salvadori explains the theory and techniques of structural engineering : not only why structures stand up, but also why sometimes they fall down. Celebrating the beauty of architecture and our instinctive recognition of satisfying structures, Dr. Salvadori shows the connection between the technique and its fruits, especially in the adventures of building such masterpieces as the Eiffel Tower, Hagia Sophia, and the Brooklyn Bridge. Why Buildings Stand Up is a perfect primer for the beginner and a treasurehouse of insights for the professional." -- from back cover. Printed in black-and-white.
