This book gives what it promises, a succinct description of the structural and engineering principles behind building, along with a few histories of major landmarks. The book will explain to you the difference between the dead loads (the actual weight of the construction materials), the live loads (the people and furniture and equipment that move in or on a building), and the dynamic loads (such as wind, thermal warping, earthquake stresses, etc.), along with how engineers compensate for each. It will explain the differences between compressive and tensile forces, and how some materials, such as stone or concrete, are great at compressive stress (up to hundreds of thousands of pounds per square inch), but have very little tensile, or stretching, strength (which is why reinforced concrete, with added steel, provides so much more stability, since the steel adds tensile strength). It will explain to you why flying buttresses in Gothic Cathedrals take the outward thrust caused by the compressive force of the roofs and buildings and turn them into downward compression, by using a straight line out to follow the stresses and a powerful arch to absorb the dead load of the materials themselves, along with towering pinnacles which help press the materials downward further and prevent their buckling outwards.
The canned histories of the Eiffel Tower, the Brooklyn Bridge, the Pyramids and so on are a little lazy, and often contain significant errors, and some of the structural principles could be more clearly explained or organized, but overall I learned a lot from this book, and would recommend it to those interested in learning the basics of the engineering that surrounds us.
