About the reasons for structural collapse, including earthquakes, metal fatigue, and terrorism.

The authors examine buildings of all kinds, from ancient domes like Istanbul's Hagia Sophia to the state-of-the-art Hartford Civic Arena. Their subjects range from the man-caused destruction of the Parthenon to the earthquake damage of 1989 in Armenia and San Francisco. The stories that make up Why Buildings Fall Down are in the end very human ones, tales of the interaction of people and nature, of architects, engineers, builders, materials, and natural forces all coming together in sometimes dramatic (and always instructive) ways.

Here is a clear and enthusiastic introduction to building methods from ancient time to the present day, illustrated throughout with line drawings. In addition, Mr. Salvadori discusses recent advances in science and technology that have had important effects on the planning and construction of buildings.

What happens when the very ground beneath your feet gives way? In Collapse, Philip Wearne tells the stories behind the worst structural engineering disasters of the last fifty years, and the forensic engineers who investigated their causes. Using expert testimonies from scientific investigators, Wearne studies eleven high-profile cases of catastrophic structural collapse, from The Hyatt Regency Hotel in Kansas City and the Hartford Civic Center in Connecticut, to the Alfred P. Murrah Federal Building in Oklahoma City. Sometimes, if these disasters have a single cause, it is a small flaw that spawns a chain reaction -- for instance, the miniscule flaw in the metal of one eyebar of the Point Pleasant Bridge on the Ohio River. Usually, though, and more alarmingly, the causes are human. Mistakes, misunderstandings, incompetence, greed, and corruption: every facet of human failing is represented in these structural collapses. This makes the investigation of these failures -- by agencies like the Failure Analysis Associates, who can have close to two thousand investigations ongoing at any one time -- dirty and dangerous business. Wearne's case study takes us deep inside the ever-growing industry of forensic engineering, revealing a group of professionals dedicated to determining the cause of a collapse at any cost, while learning and applying valuable lessons from each failure. Provocative and well-written, Collapse is essential for deepening our understanding of -- and readiness for -- catastrophe.

A novel from one of the country’s most prolific and popular YA authors, this book, set in New York City on September 11th, shows us how the experiences of that day profoundly changed one teen’s life and relationships. Today is September 10, 2001, and Will, a grade nine student, is spending the day at his father’s workplace tomorrow. As part of a school assignment, all the students in his class will be going to their parents tomorrow, but Will isn’t excited about it–he’d rather sleep in and do nothing with his friends. His father doesn’t even have an exciting job like his best friend James’s father who is a fireman. Will’s dad works for an international trading company and has to wake up early every morning to commute to his office on the eighty-fifth floor in the south building of the World Trade Center in Manhattan. Will doesn’t see his father very often because of the hours he puts in at the office. He doubts that his dad will bother making time for him tomorrow even when they are supposed to be spending the day together. In this fast-paced and dramatic new novel by bestselling author Eric Walters, Will discovers a new side of his father during an event that continues to affect the world. As Will’s new teacher says, tomorrow “might be an experience that changes your entire life.”

In "The New Science of Strong Materials" the author made plain the secrets of materials science. In this volume he explains the importance and properties of different structures.

At 5:20 in the afternoon on 9/11, Building 7 of the World Trade Center collapsed, even though it had not been struck by a plane and had fires on only a few floors. The reason for its collapse was considered a mystery. In August 2008, NIST (the National Institute of Standards and Technology) issued its report on WTC 7, declaring that "the reason for the collapse of World Trade Center 7 is no longer a mystery" and that “science is really behind what we have said.” Showing that neither of these claims is true, David Ray Griffin demonstrates that NIST is guilty of the most serious types of scientific fraud: fabricating, falsifying, and ignoring evidence. He also shows that NIST’s report left intact the central mystery: How could a building damaged by fire—not explosives—have come down in free fall?

The first book in a dark fantasy YA duology by Rose Szabo, the author of What Big Teeth, about the power and danger of stories and the untold costs of keeping magic alive, perfect for fans of Rory Power and Marie Rutkoski. In River City, where magic used to thrive and is now fading, the witches who once ruled the city along with their powerful King have become all but obsolete. The city's crumbling government is now controlled primarily by the new university and teaching hospital, which has grown to take over half of the city. Moving between the decaying Old City and the ruthless New, four young queer people struggle with the daily hazards of life—work, school, dodging ruthless cops and unscrupulous scientists—not realizing that they have been selected to play in an age-old drama that revives the flow of magic through their world. When a mysterious death rocks their fragile peace, the four are brought into each other's orbits as they uncover a deeper magical conspiracy. Devastating, gorgeous, and utterly unique, We All Fall Down examines the complex network of pain created by power differentials, even between people who love each other—and how it is possible to be queer and turn out just fine.
