Available in PDF, EPUB and Kindle. Book excerpt: Design principles and procedures and maintenance practices for bridge drainage systems are evaluated in this report, which also includes recommendations for improvements on current practice. Bridges should have adequate cross-slope and grade to allow the water to run quickly into drains. Where grades permit, some states carry all the water to catch basins at the ends. An inlet box may be used to collect the runoff. Some states have detailed procedures for determining drain spacing. Debris can be controlled by keeping it out of inlet boxes, accepting and storing it so it cannot go through the system, or transporting it through. Maintenance at regular intervals is the key to the success of a drainage system. Disposal of run off water can be a simple straight drop onto the land or water beneath the bridge or a pipe system to carry the water to the local sewer system. Current practices indicate that deck cross-slope and grade should be less than 2% and 0.5% respectively; that bridge drains may be holes through the deck, fabricated inlet boxes, or catch basins at the ends of the bridge; that inlet areas should be as large as possible; that pipes should have a minimum diameter of 6 in., a miminum radius of 18 in., and a minimum slope of 2%; that cleanout plugs and elbows should be easily accessible; that there should be improved communication between designers and maintenance personnel; and most importantly, that bridge drainage systems should be regularly and carefully inspected and serviced.

Book excerpt: Bridge-deck design, at present, often includes costly bridge-deck drainage provisions. Many bridge engineers have questioned the need for bridge-deck drainage appurtenances, at least to the extent presently included in typical bridge design. This document presents criteria to determine if bridge drainage scuppers and drains are required. A design nomograph allows a rapid decision to be made. A key variable, design rain intensity, is analyzed: the rational method is reviewed and new methods for setting design rain intensity are presented that consider hydroplaning and driver vision. Regardless of the need for scuppers, bridge-end drainage is necessary, and methods are given. If scuppers are needed, this document provides sound drainage design practice for bridge drainage.

Available in PDF, EPUB and Kindle. Book excerpt: The intent of this project was to contact other agencies to identify their typical design practices and how they address bridge deck drainage. If available, the project sought to learn standard best practices that could be directly applied to Minnesota infrastructure plans to standardize and improve drainage detailing and design practices. In reviewing the online survey and follow-up interview results with the TAP, no concise, ready to implement solution was found and many of the agencies are addressing similar concerns and lack fully developed standards or guidance documents. Although no single specific solution was identified, several key lessons were identified in the interviews which should be incorporated into further investigation and development of standards.

Book excerpt: As the emphasis in construction moves from building new bridges to maintenance and rehabilitation of existing stock, bridge management is becoming an increasingly important subject. 'Bridge Management' is a comprehensive, single volume book for professionals and postgraduates on bridge management. It focuses on inspection, assessment, testing, evaluation, repair, as well as financial aspects such as whole life costing. Highly illustrated with colour, and including examples of practice and techniques drawn from around the world, the book will be invaluable to the bridge engineer. GIVES comprehensive coverage of this important subject COVERS not only testing, assessment etc but also the financial/management issues HIGHLY illustrated with line drawings and photographs including colour
Download or read book Hydraulic Performance Small Scale Bridge Deck Drains written by Qin Qian and published by . This book was released on 2012 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient removal of stormwater runoff from bridge deck surfaces is an important safety issue. This study investigates hydraulic performance characteristics of a new type of rectangular bridge deck drain. A physical modeling study was conducted to evaluate the hydraulic performance of the innovative rectangular bridge deck drain as a function of the approach discharge, different drain configurations, and bridge characteristics. Experiments included different numbers of open drains in series for variable approach discharge cross slope and longitudinal slope. Measurements included gutter flow depth (Y) and ponding width (T) at different stations along the deck, and the capture discharge and bypass discharge. A model equation is presented for predicting the capture discharge as a function of drain size (L+W), the number of open drains (N), Manning's coefficient (n), depth of approached gutter flow (Y), longitudinal slope (S0), and cross slope (Sx). For experiments considering one through five drains in series (1-5 drains), the rating curve for each individual drain is the same when the drain size is 4 by 8 inches; however, the rating curve decreases slightly with successive drains when the drain size is 6 by 8 inches.

Book excerpt: A comprehensive guide to bridge design Bridge Design - Concepts and Analysis provides a unique approach, combining the fundamentals of concept design and structural analysis of bridges in a single volume. The book discusses design solutions from the authors’ practical experience and provides insights into conceptual design with concrete, steel or composite bridge solutions as alternatives. Key features: Principal design concepts and analysis are dealt with in a unified approach. Execution methods and evolution of the static scheme during construction are dealt with for steel, concrete and composite bridges. Aesthetics and environmental integration of bridges are considered as an issue for concept design. Bridge analysis, including modelling and detail design aspects, is discussed for different bridge typologies and structural materials. Specific design verification aspects are discussed on the basis of present design rules in Eurocodes. The book is an invaluable guide for postgraduate students studying bridge design, bridge designers and structural engineers.
