Why Buildings Fall Down

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.

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

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.

WHY DO BUILDINGS COLLAPSE IN EARTHQUAKES? Learn from the personal experience and insights of leading earthquake engineering specialists as they examine the lessons from disasters of the last 30 years and propose a path to earthquake safety worldwide Why Do Buildings Collapse in Earthquakes?: Building for Safety in Seismic Areas delivers an insightful and comprehensive analysis of the key lessons taught by building failures during earthquakes around the world. The book uses empirical evidence to describe the successes of earthquake engineering and disaster preparedness, as well as the failures that may have had tragic consequences. Readers will learn what makes buildings in earthquake zones vulnerable, what can be done to design, build and maintain those buildings to reduce or eliminate that vulnerability, and what can be done to protect building occupants. Those who are responsible for the lives and safety of building occupants and visitors—architects, designers, engineers, and building owners or managers—will learn how to provide adequate safety in earthquake zones. The text offers useful and accessible answers to anyone interested in natural disasters generally and those who have specific concerns about the impact of earthquakes on the built environment. Readers will benefit from the inclusion of: A thorough introduction to how buildings have behaved in earthquakes, including a description of the world’s most lethal earthquakes and the fatality trend over time An exploration of how buildings are constructed around the world, including considerations of the impact of climate and seismicity on home design A discussion of what happens during an earthquake, including the types and levels of ground motion, landslides, tsunamis, and sequential effects, and how different types of buildings tend to behave in response to those phenomena What different stakeholders can do to improve the earthquake safety of their buildings The owners and managers of buildings in earthquake zones and those responsible for the safety of people who occupy or visit them will find Why Do Buildings Collapse in Earthquakes? Building for Safety in Seismic Areas essential reading, as will all architects, designers and engineers who design or refurbish buildings in earthquake zones.

"Readers will rejoice... in the physical discoveries, ancient and modern, that create and govern the artifacts inside of which readers spend most of their natural lives."—New York Times Between a nomad's tent and the Sears Tower lies a revolution in technology, materials, and structures. Here is a clear and enthusiastic introduction to buildings methods from ancient times to the present day, including recent advances in science and technology that have had important effects on the planning and construction of buildings: improved materials (steel, concrete, plastics), progress in antiseismic designs, and the revolutionary changes in both architectural and structural design made possible by the computer.

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.”
