First published in 1983, this guide has established itself as a popular text for civil engineers and professionals, from a range of disciplines, concerned with the practice of land drainage and the legal implications of drainage operations.This fourth edition has been fully updated to reflect the significant changes in legislation and statutory bodies since the last edition was published. This includes the move to a risk-based approach in environment management and the planning process, resulting in greater control of development on flood plains.

Sponsored by the Ocean and Offshore Engineering Committee of the Coasts, Oceans, Ports, and Rivers Institute of ASCE.
Spar Platforms: Technology and Analysis Methods examines the design, analysis, and use of spar platforms for offshore oil production. Since the first spar platform, the Oryx Neptune, was installed in the Gulf of Mexico in 1996, spars have evolved into a proven, reliable technology for oil drilling and production in deep and remote areas. Three spar concepts are in use today: the classic spar, the truss spar, and the cell spar. Although the technology and analysis methods are considered mature, technical challenges remain, including understanding and suppressing vortex-induced motion and improving survivability in category 4 and 5 hurricanes.
This volume surveys the history of spar development and presents detailed design modeling aspects of spar hull, mooring, and anchoring systems. Two methodologies—the diffraction method and the Morrison formula—that can be used to analyze spar motions are demonstrated and assessed. Design considerations for vortex-induced motion of spars are weighed, along with possible remedies. In addition, testing methods for spar models in wave basins are considered, and full-scale field data is compared with the results of several numerical analysis tools.
Ocean and coastal engineers, those involved in the design and construction of offshore structures, and petroleum engineers will find the book a useful supplement to existing specifications for spar platforms.

Piers, Jetties and Related Structures Exposed to Waves: Guidelines for Hydraulic Load
Author: Kirsty McConnell, William Allsop and Ian Cruickshank | Size: 7.5 MB | Format:PDF | Quality:Unspecified | Publisher: Thomas Telford Ltd | Year: 2004 | pages: 133 | ISBN: 9780727732651
Jetties, piers and other marine structures constructed in exposed locations require careful assessment of their hydraulic loads. Increasingly trade economics are leading to larger ship sizes and existing and new port locations for these vessels require longer jetties in significantly deeper water. In these instances construction of protective breakwaters becomes substantially more expensive, so in some cases jetties or their approach trestles are being constructed in exposed locations without breakwater protection. These guidelines will help maritime designers to optimise jetty designs, and are an essential reference resource.
Key coverage:
> Guidance on hydraulic design, including design wave conditions, prediction of scour and vessel mooring loads
> New methods (developed from extensive laboratory testing) for the prediction of wave loading, including forces on the underside of jetty decks.
This book provides new guidance on design principles and design wave loads for exposed jetty structures where guidance has not previously been available.
Contents:
Introduction
Definitions of exposed jetties, typical locations and exposures
Aspects of design
Wave forces on vertical elements
Wave forces on horizontal elements
Berthing and mooring loads
Scour
Other design and construction issues
References

This book presents a complete how-to procedure for the design of shallow foundations commonly used with low-rise structures of today's building codes. It offers a detailed presentation of both soils and structures specifically as they relate to shallow foundations, emphasizing soil-structure interaction by matching particular structural designs to particular soil conditions. For soils, the author describes relevant soil properties and soil mechanics at shallow depths. For structures, the author includes a summary of loads on foundations and the deformations produced by such loads. Design procedures apply to structures less than 65 feet tall and having a natural period of oscillation less than 0.90 seconds. Structural systems include low-rise diaphragm/shearpanel systems, braced frames, and rigid frames.
These established and proven methods apply to industries of architecture, construction, engineering technology, as well as civil engineering, and are intended for use by both students and practitioners.

Significant Changes to the Wind Load Provisions of ASCE 7-10 : An Illustrated Guide
Author: T. Eric Stafford, P.E. | Size: 3.82 MB | Format:PDF | Quality:Original preprint | Publisher: S. K. Ghosh Associates Inc | Year: 2010 | pages: 122
Significant Changes to the Wind Load Provisions of ASCE 7-10: An Illustrated Guide focuses on the updates to the wind load requirements set forth in the latest edition of the Standard for minimum design loads. The wind load provisions have undergone the most extensive revision since the 1995 edition the Standard. Mirroring the organization of the wind chapters in ASCE 7-10, this handy reference briefly summarizes each change to the wind provisions that might affect actual practice or enforcement and immediately follows up with the precise wording of the change. The impact of each update is explained in clear, straightforward language accompanied by diagrams, examples, and color photographs and illustrations to enrich the reader's understanding.
Significant Changes to the Wind Load Provisions of ASCE 7-10: An Illustrated Guide translates the changes to the wind load provisions of Standard ASCE/SEI 7-10 into a form readily accessible by structural engineers, architects, contractors, building officials and inspectors, and allied professionals.

Extensive amounts of operational data are generated over time by the health monitoring system of a structure’s management system, yet there are few analysis algorithms which can tell the exact working state of the structure on-line. Good maintenance engineers need to know the exact location and state of the structural components after an earthquake or some attack or accident involving the structure, possibly within a matter of hours, and the client also demands a rapid diagnosis of the structure before making decisions on any necessary remedial work.
This book is devoted to the condition assessment of a structure under operational loading, with most of the illustrations related to a bridge deck under a group of moving vehicular loads. More generally, a wide variety of excitation forces can be exerted on a structure, from earthquake excitation, wind loading, vehicular loading or ambient excitation at the supports. Different algorithms may be used to enable real time identification with deterministic results on the state of the structure. This book also covers a group of damage-detection-oriented-models developed by the author, including a new decomposition of the system matrices of the beam element and plate element. Methods for extending the deterministic condition assessment to provide statistical information are also included. The methods and algorithms described can be implemented for the on-line condition assessment of a structure through model updating of the structure during the course of extreme loading such as an earthquake, or when under normal ambient excitation or operation excitation. Different sample structures are described and analysed, supplemented with major references.
This leading-edge work will be especially useful for researchers and graduate students, and it is also heavily rooted in advanced engineering practice.
