New Uses for Old Bridges
As historic bridges age, they are often rendered useless by modern load requirements and codes. Many had been abandoned or demolished. In 1991, however, the ISTEA created new provisions...
Degradation of Natural Building Stone
This proceedings,
Construction Safety Affected by Codes and Standards
These five papers present an insight into, and highlights of, some very recent design/construction standardization activities in the US, Canada, Great Britain, Japan and Israel. New performance-type...
Forensic Engineering
This proceedings contains the papers resented at the First Forensic Engineering Congress, a special part of the American Society of Civil Engineers Annual Convention held in Minneapolis,...
Seismic Analysis and Design for Soil-Pile-Structure Interactions
Pile foundations are used extensively to support structures in seismic regions around the world. For years, geotechnical engineers have neglected to consider the interaction soil-pile...
Stabilizing the Stacks
Spenser White and Prentis designed a hybrid soil nailing system to ensure that a historic library on the Bryn Mawr, Pennsylvania, campus would not be damaged during adjacent construction...
Wind Endurance
Although property casualty insurance companies are interested in a building's resistance to intense winds, risk underwriters traditionally take into account few, if any, wind-performance...
Grand Gusset Failure
In May 1996, structural failure forced the closure of twin 850 ft long arched truss bridges, each carrying two lanes of interstate traffic over the Grand River, 30 mi east of Cleveland....
Guide to the Use of the Wind Load Provisions of ASCE 7-95
The objective of the Guide to the Use of the Wind Load Provisions of ASCE 7-95 is to provide guidance in the use of the wind load provisions set forth in ASCE Standard 7-95. The Guide...
Design
This chapter discusses guyed structure design. Topics include loadings and design restrictions; guy clearances; guy design; guy anchorage; connections; structural design of poles and H-frames;...
Examples
This section includes several examples that illustrate many of the concepts presented in this guide. The examples and load cases have been simplified and may not represent actual design...
Communication Breakdown
Are modern telecommunications networks vulnerable to earthquakes? Researchers say yes, and have developed a computer tool to quantify potential economic impacts. Telecommunications service...
Cable Corrosion in Bridges and Other Structures:
Causes and Solutions
This book provides the reader with basic facts concerning cable corrosion and means to avoid or rehabilitate corrosion damage. Corrosion problems associated with cable-supported structures...
Historical Development of Bridge Scour Evaluations
Scour of bridge foundations (piers and abutments) is the largest single cause of bridge failures in the United States. Conversely, uncertainties of the scour depth at bridge piers and...
Hydraulics of Subsurface Flow Constructed Wetlands
Resistance to flow through subsurface flow wetlands is described by Darcy's law or by Ergun's equation. Both representations are combined with the continuity...
Efficient Pump Representation for Fixed-Grid MOC in Pipeline Systems
An explicit solution of the pump power failure boundary condition is shown to have many computational advantages over the conventional implicit pump boundary condition solution (i.e.,...
Estimation of Bed Material Transport Capacity
A procedure is presented which combines several computational components for the estimation of bed material transport capacity in alluvial channels. Bed load transport is estimated through...
Upper Chehalis River Pollutant Capacity and Load Allocations
Dry season water quality was evaluated in the Upper Chehalis River in western Washington state, focusing on low dissolved oxygen (DO), and using the Total Maximum Daily Load (TMDL) process....
Suspended Sediment Loads in Dry and Wet Years
Many factors other than water discharge influence the suspended sediment load in rivers. The climate condition is one of the factors. It is expected that the relation between Qs...
Bridge Hydraulic and Scour Analysis Using FESWMS-2DH
Stream crossings are usually designed to satisfy all engineering and enviromnental constraints at the lowest possible cost. As a result, roadway approach embankments leading to bridge...
