Superstructures

Showcases the most ambitious, awe-inspiring and advanced engineered structures of the last 100 years.

Cubes, triangular prisms, nano-acorn, nano-centipedes, nanoshells, nano-whiskers. . . . Now that we can create nanoparticles in a wide variety of shapes and morphologies, comes the next challenge: finding ways to organize this collection of particles into larger and more complex systems.

A How-To Guide for Bridge Engineers and DesignersHighway Bridge Superstructure Engineering: LRFD Approaches to Design and Analysis provides a detailed discussion of traditional structural design perspectives, and serves as a state-of-the-art resource on the latest design and analysis of highway bridge superstructures. This book is applicable to hig

From the Ancient Pyramids to the Eiffel Tower, get ready to take a close-up look at some awesome man-made structures. This unique, interactive book not only traces the history of the world’s most impressive, man-made mega structures from ancient times to the modern age, but also explores the science behind these incredible engineering feats. Discover the science of architecture behind different types of super structures, including bridges, domes and towers, then use this knowledge to have ago at creating your own from the model kit! Using card pieces, plastic connectors and string, you can make the different types of constructions – including an Egyptian pyramid, the Golden Gate Bridge and the Eiffel Tower - and then conduct tests to see how they work!

Concrete bridges are an important part of today's road infrastructure. An important part of those concrete bridges is to a large extent prefabricated. Precast concrete enables all the advantages of an industrialized process to be fully utilized. Contemporary concrete mixtures are used to realize high-strength bridge girders and piers that exactly meet the requirements set, both structurally and aesthetically, with a small ecological footprint. Sustainable and durable! On the construction site, there is no need for complex formwork, the execution time is drastically reduced and where road, water and rail traffic on or under the bridge has to be temporarily interrupted, it is only minimally inconvenienced during the execution of the project. Bridges capture the imagination. In addition to their pure functionality, overcoming a height difference, they offer designers unprecedented opportunities to shape their creativity, including when using precast concrete. This bulletin, prepared by the experts of Task Group 6.5 'Precast concrete bridges', takes a closer look at the conceptual (preliminary) design of prefabricated concrete bridges. The bulletin does not have the ambition to define the umbrella term 'conceptual design' but shows in a pragmatic way, using 24 examples spread all over the world, how leading designers use this methodology to select from the many possibilities to arrive at an ideal solution taking into account all design conditions. One often reads that experience is a necessary condition for good conceptual design. The pooled knowledge and experience in this bulletin already provide the reader with a good head start. Commission 6 thanks the former convener of the Task Group Hugo Corres, editor of this document, and the current co-conveners Marcello Waimberg and Ken-ichi Kata as well as all active members of the Task Group for sharing their knowledge and experience and for the successful realization of this bulletin.

These standardized bridge plans are for superstructures consisting of treated timber. Seven superstructure types are included: five longitudinal and two transverse deck systems. Both HS20 and HS25 loadings are included, along with L/360 and L/500 deflection criteria.

A How-To Guide for Bridge Engineers and Designers Highway Bridge Superstructure Engineering: LRFD Approaches to Design and Analysis provides a detailed discussion of traditional structural design perspectives, and serves as a state-of-the-art resource on the latest design and analysis of highway bridge superstructures. This book is applicable to highway bridges of all construction and material types, and is based on the load and resistance factor design (LRFD) philosophy. It discusses the theory of probability (with an explanation leading to the calibration process and reliability), and includes fully solved design examples of steel, reinforced and prestressed concrete bridge superstructures. It also contains step-by-step calculations for determining the distribution factors for several different types of bridge superstructures (which form the basis of load and resistance design specifications) and can be found in the AASHTO LRFD Bridge Design Specifications. Fully Realize the Basis and Significance of LRFD Specifications Divided into six chapters, this instructive text: Introduces bridge engineering as a discipline of structural design Describes numerous types of highway bridge superstructures systems Presents a detailed discussion of various types of loads that act on bridge superstructures and substructures Discusses the methods of analyses of highway bridge superstructures Includes a detailed discussion of reinforced and prestressed concrete bridges, and slab-steel girder bridges Highway Bridge Superstructure Engineering: LRFD Approaches to Design and Analysis can be used for teaching highway bridge design courses to undergraduate- and graduate-level classes, and as an excellent resource for practicing engineers.

An “extraordinary guide to the hidden secrets of modern man-made miracles . . . Highly recommended” —from the author of Froth!: The Science of Beer (Midwest Book Review). Ever wonder how a graceful and slender bridge can support enormous loads over truly astonishing spans? Why domes and free-standing arches survive earthquakes that flatten the rest of a city? Physicist Mark Denny looks at the large structures around us—tall buildings, long bridges, and big dams—and explains how they were designed and built and why they sometimes collapse, topple, or burst. Denny uses clear, accessible language to explain the physics behind such iconic structures as the Parthenon, the Eiffel Tower, the Forth Rail Bridge in Edinburgh, and Hoover Dam. His friendly approach allows readers to appreciate the core principles that keep these engineering marvels upright without having to master complex mathematical equations. Employing history, humor, and simple physics to consider such topics as when to use screws or nails, what trusses are, why iron beams are often I-shaped, and why medieval cathedrals have buttresses, Denny succeeds once again in making physics fun. Praise for Mark Denny “Denny’s wry humor is fun to read and made me laugh out loud.” —Mark Kidger, author of Astronomical Enigmas “Denny largely sheds the complexity of mathematical constructs, distilling their most salient features into a more qualitative understanding of radar and sonar systems.” —Choice “Indeed, Denny’s writing is anything but dry and boring. He adeptly explains complex subject matter and does so with relatively simple language and minimal use of symbolic notation.” —Bat Research News
