Holding Up
Now that the redevelopment of the World Trade Center site is under way, the time is right to examine the status of the remaining slurry wall foundation system and consider how future construction...
Impact of Chemically-Induced Clay Transport and Deposition on the Hydraulic Conductivity of a Natural Sand
The purpose of this paper is to understand in part the dynamic impact of surfactants on hydraulic conductivity for designing enhanced pump and treat operations. This paper has two aims:...
Bayesian Approach to Support Design of a Groundwater Long Term Monitoring Plan
This paper discusses a retrospective data assimilation approach that allows one to examine the spatial and temporal differences between forecast and observed states. Their stability, or...
Great Hall
One of the most provocative structures gracing the London landscape, the new City Hall, at More London, is also a world-class model of energy-efficient design....
Enduring Strength
The long-term effectiveness of posttensioning in bridges depends on the resiliency of the tendons, and various factors related to construction and marine environments come into play. How...
Grand Finale
For 87 years Oklahoma's state capitol remained unfinished, the majestic cast-in-place concrete dome its designers envisioned never built. But as Oklahoma approached its centennial�to...
Island in the Mur
Floating atop an immense pontoon like a shimmering seashell, this elliptical island of steel and glass in the middle of an Austrian river�an inventive, unconventional bridge�was designed...
A Culvert for Abram Creek
To enable Cleveland's airport to expand, a mile-long section of stream located within a deep, steep ravine needed to be buried. The resulting culvert required a design that...
Failures and Problems with Lift-Slab Construction
This chapter provides an overview of failures and problems with lift-slab construction. Topics include jack systems with inadequate take-up devices; the Canadian wedge connection; Serra...
Lifting Collars and Lifting Equipment
The terms lifting collars and shear heads are used interchangeably in the industry. In this book the term lifting collar is used since it is a unique term applicable to lift-slab construction...
Initial Considerations
The purpose of this section is to aid the line designers in developing their specifications for fiber-reinforced polymer (FRP) materials utilized in electric overhead line structures....
Materials and Manufacturing Processes
This chapter introduces the basic materials used in the manufacturing of composite structures. It will help the line designer in understanding how the different elements of the fiber-matrix...
Design Loads
This chapter discusses the types of loadings that should be considered when designing overhead power lines utilizing fiber-reinforced polymer (FRP) poles. For infrastructure applications...
Performance-Based Criteria for FRP Products and Materials
In most ways, fiber-reinforced polymer (FRP) structures perform similar to wood and steel structures. There are, however, certain differences and these differences are described in this...
Assembly and Erection
This chapter is intended to provide recommendations on transporting, handling, assembling, and erecting fiber-reinforced polymer (FRP) poles. An important consideration is that FRP poles...
