Quote:fib Bulletin 61 is a continuation of fib Bulletin 16 (2002). Again the bulletin’s main objective is to demonstrate the application of the FIP Recommendations “Practical Design of Structural Concrete”, and especially to illustrate the use of strut-and-tie models to design discontinuity regions (D-regions) in concrete structures.
Bulletin 61 presents 14 examples, most of which are existing structures built in recent years. Although some of the presented structures can be considered to be quite important and, in some instances, complex, the chosen examples are not intended to be exceptional. The main aim is to look at specific design aspects, by selecting D-regions of the presented structures that are designed and detailed according to the proposed design principles and specifications for the use of strut-and-tie models.

Over the past 25 years, Harold and Darren Franck have investigated hundreds of accidents involving vehicles of almost every shape, size, and type imaginable.
In Mathematical Methods for Accident Reconstruction: A Forensic Engineering Perspective, these seasoned experts demonstrate the application of mathematics to modeling accident reconstructions involving a range of moving vehicles, including automobiles, small and large trucks, bicycles, motorcycles, all-terrain vehicles, and construction equipment such as hoists and cranes.
The book is anchored on basic principles of physics that may be applied to any of the above-named vehicles or equipment. Topics covered include the foundations of measurement, the various energy methods used in reconstruction, momentum methods, vehicle specifications, failure analysis, geometrical characteristics of highways, and softer scientific issues such as visibility, perception, and reaction.
The authors examine the fundamental characteristics of different vehicles, discuss the retrieval of data from crash data recorders, and review low speed impacts with an analysis of staged collisions. Finally, the book details standards and protocols for accident reconstruction.
Exploring a broad range of accident scenarios and also acknowledging the limits of applicability of the various physical methods employed, the breadth and depth of the book’s coverage makes it a critical reference for engineers and scientists who perform vehicular accident reconstructions.

I have to make a presentation about the experiments I've conducted - shear strength of RC columns with circular cross section... So I have the clip of the experiment - from the beginning to the failure of the specimen, and the all the data - time, load, deformations.
For the presentation, I want to combine the failure movie with syncronized animated graph Time-Load and Load-Deformations.
Airframe and Powerplant Mechanics: Airframe Handbook
Advisory Circular Series No. 65-15a
Size: 30 MB | Format:PDF | Quality:Scanner | Publisher: U.S. Department of Transportation, Federal Aviation Administration | Year: 1976 | Pages: 609 | ISBN: 9780160362095, 0160362091
It is intended that this handbook will provide basic information on principles, fundamentals and technical procedures in the subject matter areas relating to the airframe rating. It is designed to aid students enrolled in a formal course of instruction as well as the individual who is studying on his own. Since the knowledge requirements for the airframe and powerplant ratings closely parallel each other in some subject areas, the chapters which discuss fire protection systems and electrical systems contain some material which is also duplicated in the Airframe and Powerplant Mechanics Powerplant Handbook.

The Detail in Building series is an essential source of contemporary data covering the key elements of building design that form the vocabulary of current architecture. Previous titles include Staircases, Soft Canopies, Glass Canopies, Columns, Cable Nets and Wind Towers, and a publication on Balconies is currently in preparation. Each is clearly analysed, both historically and in terms of recent examples by key practices around the world. The combination of building context, design aesthetics and technical solution, as revealed in the case studies, is highly informative as well as unique in a field where specific technical quality of design detailing is often insufficiently exposed by the superficial presentation of designs. Service Cores, the seventh title in the series, deals with the internal vertical cores of buildings: the parts that contain the elevators, elevator-shafts, lobbies, staircases, mechanical, electrical and IT riser ducts, toilets and other components necessary both for environmental servicing and to provide access to the building's usable spaces. Initially associated mainly with skyscrapers and science buildings, service cores are becoming equally essential in the design of other highly-serviced building types, from laboratories and high-tech buildings to hotels, shopping malls and stadiums. The author discusses the historical treatment and development of service cores, and provides an outline guide to the considerations required in their design. This is supported by a series of case studies, featuring mainly skyscraper buildings from all over the world by a range of architects of international renown.

With Wind Wizard, Siobhan Roberts brings us the story of Alan Davenport (1932-2009), the father of modern wind engineering, who investigated how wind navigates the obstacle course of the earth's natural and built environments--and how, when not properly heeded, wind causes buildings and bridges to teeter unduly, sway with abandon, and even collapse.
In 1964, Davenport received a confidential telephone call from two engineers requesting tests on a pair of towers that promised to be the tallest in the world. His resulting wind studies on New York's World Trade Center advanced the art and science of wind engineering with one pioneering innovation after another. Establishing the first dedicated "boundary layer" wind tunnel laboratory for civil engineering structures, Davenport enabled the study of the atmospheric region from the earth's surface to three thousand feet, where the air churns with turbulent eddies, the average wind speed increasing with height. The boundary layer wind tunnel mimics these windy marbled striations in order to test models of buildings and bridges that inevitably face the wind when built. Over the years, Davenport's revolutionary lab investigated and improved the wind-worthiness of the world's greatest structures, including the Sears Tower, the John Hancock Tower, Shanghai's World Financial Center, the CN Tower, the iconic Golden Gate Bridge, the Bronx-Whitestone Bridge, the Sunshine Skyway, and the proposed crossing for the Strait of Messina, linking Sicily with mainland Italy.
Chronicling Davenport's innovations by analyzing select projects, this popular-science book gives an illuminating behind-the-scenes view into the practice of wind engineering, and insight into Davenport's steadfast belief that there is neither a structure too tall nor too long, as long as it is supported by sound wind science.
