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...

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...
Construction Through Crude Oil
When the Hilltop Interceptor project in Cleveland confronted oil-saturated sandstone, designers had to rethink their shaft construction and support procedures. Among the hazards were volatile...
Financing the Future of Storm Water
For Sarasota County, Fla., draining storm water no longer means draining municipal funds. By establishing a modern storm-water utility, the county has provided a dedicated funding source...
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...
Application of a Hydrodynamic Model in Design of the Kingman Lake Wetland Restoration Project
The U.S Army Corps of Engineers Baltimore District is restoring 45 acres of wetlands within Kingman Lake in the District of Columbia through the placement of dredged material from the...
Features of a Chevron Weir Rock Ramp
This paper presents the features of a new type of low profile grade control structure, the chevron weir rock ramp. As the name infers, the planform of the structure is in the shape of...
Application of High-Resolution Schemes to Free Surface Flows in Irregular Channels
A 1-D flow model employing a high resolution scheme based on the Total Variation Diminishing concept is applied to non-prismatic channels of irregular cross-section. The hydraulic properties...
Hydraulic and Engineering Considerations in Designing Constructed Treatment Wetlands for a Lake Restoration
A 12,600 ha (31,000 acre) hypereutrophic lake in central Florida is being restored by constructing a 2,020 ha (5,000 acre) wetland filter to remove suspended sediments and particulate...
Water Control Structure Choice for Wetland Restoration/Creation
Ducks Unlimited is a non-profit conservation organization, whose mission is to fulfil the annual life cycle needs of North American waterfowl by protecting, enhancing, restoring, and managing,...
Effect of Grade Control Structures on DEC Streams
Controlling the grade of a channel with structures has been an effective means applied to streams. Although, the effectiveness of grade control structures is not readily apparent until...
