Abstract:
For a long time, new tower designs have been validated by loading tests. IEC 60652, Loading Tests on Overhead LineStructures, was first published in 1979 to standardize and provide guidance for performing Tests. After some years of practical experience with that standard, WG B2.08 decided to review its application. With this objective two questionnaires were circulated. A summary of the answers and the relevant conclusions are shown in the TB

From game theory to the Gambler’s ruin this book has classical mathematics well explained. The section on permutations and multinomials is still a valuable reference after all these years! But it is the application of permutation groups to island marriage laws that make this book a mathematical classic! How close a relative can you marry without endangering the gene pool while maximizing the number of people in your tribe that you can marry… a practical problem set to a primitive culture produced mathematical solutions!

Synopsis:
A software system called as TOWTEST has been developed to help in the various aspects of tower testing operations such as stub setting, tower rigging and control channel settings. The software helps in designing a loading scheme wherein hydraulic rams are employed to apply loads, on different points of a tower, by the resultant load-application method. The software also helps in making necessary, presettmgs of the control system consisting of custom built control channels with recorders to monitor load cell, angle cell, and hydraulic ram operations. The software produces tabular statements and rigging drawings, which serve as ready reckoner during various stages of tower test operations starting right from the test tower erection

Hello,
My name is Ross and I am one of the senior members of the profession in Australia with 40+ years experience.
I am a Fellow of the Institution of Engineers Australia and the managing director of a small to medium sized consulting engineering firm with structures as our core function.
Personally I have two passionate interests the first being modular building technology as a future direction for the building construction industry internationally and the second the role of Engineering as a profession to solve some of the worlds major issues. The one close to my heart is the provision of shelter (housing) and associated infrastructure to the worlds 2 + billion people that live in substandard cnditions.
Strength and Related Properties of Concrete: A Quantitative Approach
by
Sándor Popovics
Wiley, 23-Mar-1998 - 535 pages
Quantitative tools for evaluating and improving the strength of concrete
Concrete is a complex material of vital importance to the civil engineering and construction industries. Strength and Related Properties of Concrete addresses the most important single property of concrete--its strength--with the goal of contributing to concrete's technical and economical improvement. The book is unique in containing, in a single volume, all of the quantitative tools needed to evaluate, understand, and improve concrete quality.
This hands-on guide demonstrates how to fine-tune the composition of concrete to maximize its strength. It presents the best numerical relationships for concrete technology that are currently available, examines them experimentally, and illustrates their practical applications. It also provides a basis for improving both the fundamentals of concrete technology and the way this technology is taught to engineering students. Computerized formulas for strength testing are included on a floppy disk.
Topics covered include:
* Proven methods for testing compressive strength
* Important relationships between composition and strength of concrete
* Timely applications of advanced cement-based materials
* Elastic deformations of concrete
* Essential properties of cement pastes
Hydrodynamics of High-Speed Marine Vehicles, first published in 2006, discusses the three main categories of high-speed marine vehicles - vessels supported by submerged hulls, air cushions or foils. The wave environment, resistance, propulsion, seakeeping, sea loads and manoeuvring are extensively covered based on rational and simplified methods. Links to automatic control and structural mechanics are emphasized. A detailed description of waterjet propulsion is given and the effect of water depth on wash, resistance, sinkage and trim is discussed. Chapter topics include resistance and wash; slamming; air cushion-supported vessels, including a detailed discussion of wave-excited resonant oscillations in air cushion; and hydrofoil vessels. The book contains numerous illustrations, examples and exercises.

This book presents sloshing with marine- and land-based applications, with a focus on ship tanks. It also includes the nonlinear multimodal method developed by the authors and an introduction to computational fluid dynamics. Emphasis is also placed on rational and simplified methods, including several experimental results. Topics of special interest include antirolling tanks, linear sloshing, viscous wave loads, damping, and slamming. The book contains numerous illustrations, examples, and exercises.
