Seismic Design and Analysis of Tanks A detailed view on the effects of seismic activity on tank structures As the use of above-ground and underground storage tanks (ASTs and USTs) continues to grow—with approximately 545,000 in the USA alone—the greatest threat to ASTs and USTs is earthquakes, causing the contamination of groundwater, a vital source of drinking water throughout the world. These tanks suffer a great deal of strain during an earthquake, as a complicated pattern of stress affects them, such that poorly designed tanks have leaked, buckled, or even collapsed during seismic events. Furthermore, in oil and gas industrial plants, the risk of damage is even more critical due to the effects of explosion, collapse, and air or soil contamination by chemical fluid spillages. Seismic Design and Analysis of Tanks provides the first in-depth discussion of the principles and applications of shell structure design and earthquake engineering analyses focused on tank structures, and it explains how these methodologies can help prevent the destruction of ASTs and USTs during earthquakes. Providing a thorough examination of the design, analysis, and performance of steel, reinforced concrete, and precast tanks, this book takes a look at tanks that are above-ground, underground, or elevated, anchored and unanchored, and rigid or flexible, and evaluates the efficacy of each method during times of seismic shaking—and it does so without getting bogged down in impenetrable mathematics and theory. Seismic Design and Analysis of Tanks readers will also find: A global approach to the best analytical and practical solutions available in each region: discussion of the latest US codes and standards from the American Society of Civil Engineers (ACSE 7), the American Concrete Institute (ACI 350,3, 371.R), the American Water Works Association (AWWA D100, D110, D115), and the American Petroleum Institute (API 650) an overview of the European codes and standards, including Eurocode 8-4 and CEN-EN 14015 Hundreds of step-by-step equations, accompanied by illustrations Photographs illustrating real-world damage to tanks caused by seismic events Perfect for practising structural engineers, geotechnical engineers, civil engineers, and engineers of all kinds who are responsible for the design, analysis, and performance of tanks and their foundations—as well as students studying engineering—Seismic Design and Analysis of Tanks is a landmark text, the first work of its kind to deal with the seismic engineering performance of all types of storage tanks.

Cornwall, 1900s. Plyn Boat Yard is a hive of activity, and Janet Coombe longs to share in the excitement of seafaring: to travel, to have adventures, to know freedom. But constrained by the times, instead she marries her cousin Thomas, a boat builder, and settles down to raise a family. Janet's loving spirit - the passionate yearning for adventure and for love - is passed down to her son, and through him to his children's children. As generations of the family struggle against hardship and loss, their intricately plotted history is set against the greater backdrop of war and social change in Britain. Her debut novel, The Loving Spirit established du Maurier's reputation and style with an inimitable blend of romance, history and adventure.

An amazing tale of heroism and ingenuity, this dramatic picture book tells the story of Sir Ernest Shackleton's incredible adventure in the heroic age of Antarctic exploration. August, 1914: Shackleton sets off from England with a team of explorers to walk across the Antarctic and study the icy depths of this little-known and forbidding continent. Sailing through some of the most perilous seas, the Endurance becomes trapped in the deadly pack ice of the Weddell Sea. When the Endurance is eventually crushed between the vast bulk of two floating icebergs, the men are forced to abandon ship and make the dangerous journey across the crushing sea in lifeboats. They reach relative safety on the uninhabited Elephant Island, but an even greater peril faces Shackleton and five other members of the crew… An incredible real-life story of perseverance, resilience and cooperation in the face of adversity, Ice Trap! makes Shackleton’s most perilous expedition accessible to a new generation of readers. As we approach the 100th anniversary of Shackleton’s death, keep his legacy alive with this exciting and beautifully illustrated telling of his boldest journey.

Now a USA Today Bestseller! A sparkingly witty, poignant debut novel that is a Bright Lights, Big City for a post-Reagan, pre-Y2K Philadelphia—for readers of Normal People, Sweetbitter, Modern Lovers, and Less. It’s September 1987. Charlie Green is an eighteen-year-old romantic and aspiring alcoholic, whose great wish is to fall in love with a light-eyed girl on his first day of college and never look back. Charlie believes in the magic of bars and girls. He believes he can use these talismans to finally feel at home, an assurance his dim and privileged childhood did not provide. At the Sansom Street Oyster House, he meets Paula Henderson, a beautiful and deceptively soulful waitress who is the most overqualified bar maid in all the city—and perhaps the most alluring. But there are obstacles in the Philly night between Charlie and his full heart. Drunks, louts, boyfriends—heroes too. And in Paula’s eyes, Charlie becomes one. When she takes him home to New Hope, PA, to meet her very Catholic mother, the young couple must contend with the consequences of their pure love. In this darkly comedic coming-of-age novel, Charlie Green needs to grow up fast. At stake is his soul.

Was the purpose of an Iron Age hillfort to defend people and resources or was it there to show the power of the community and its leaders? Was the Middle Iron Age trend to large complex ‘defences’ a response to developing tactics of assault or did the huge amounts of construction work serve the purpose of building community identity through shared labour? The name ‘hillfort’ implies a defensive purpose, but in recent decades alternative interpretations have gained favour, based on analyses suggesting that hillforts are poorly suited to military purposes and on views of Iron Age society that emphasise the importance of boundaries, symbolic display and communitybuilding. Excavations of hillfort interiors reveal they were sites for many activities; large caches of stones suggest that sling warfare was one. This book reports an investigation of these issues. Sling accuracy at a hillfort was measured for the first time, in a controlled experiment comparing attack and defence across single and developed ramparts. Tactical scenarios modelled from the results showed that hillfort development gave defenders increased advantage. These results support defence as the explanation for the features of the enclosing works of hillforts. Full details of the method and analyses are included.
