Seismic Rehabilitation: Why, When and How
Common methods of seismic rehabilitation are: repair of cracks, reconstruction of structural elements, addition of stiffening elements, and addition of dampers. A major consideration is...
Thoughts on a Different Approach to Seismic Design Codes
The aim of this paper is to show that some of the principles on which conventional structural design is based are not directly applicable to seismic design. Seismic design, and the corresponding...
Crossing A Freeway
The Washington State Convention and Trade Center in Seattle is being constructed on air rights spanning Interstate-5, adjacent to the seven acre Freeway Park that also spans the highway....
Transmission Structure Foundation Loads and Performance
Transmission line structures are subjected to unique loading conditions which for the majority of structures results in maximum loads which occur infrequently and act for only short periods...
Engineering Aspects of Point Versus Nonpoint Sources of Groundwater Pollution
Pollution of groundwater may occur due to a number of sources. These may be categorized into point and nonpoint sources of contamination. The purpose of this paper is to explore the issues...
Agricultural Nonpoint Source Control Program for Lake Erie
The Lake Erie Wastewater Management Study was directed at identifying and quantifying sources of P and sediment entering the lake, developing a management control strategy, and projecting...
Building Around a Building
Many, maybe most, construction disasters occur as the result of the failure of temporary structures. Despite the fact that temporary structures have a critical effect on the speed, safety...
Strengthening Old Floors
The floors of the historic City Hall and Courthouse in Minneapolis had withstood 80 years of hard use before they have to be analyzed and brought up to code. The building is about 300...
A Regional Screening Method for Classifying Pollutant Status of Coastal Waters
A regional assessment method has been developed to classify estuaries on the basis of their pollution severity, enabling resource managers to prioritize clean-up and future research efforts....
Albemarle-Pamlico Sounds: Issues, Resources, and Management (
The Albemarle-Pamlico Sound complex, located in northeastern North Carolina, is the third largest estuarine complex in North America and the second largest in area in the United States....
The Impact of Suburbanization on an Urban River
A case study of the impacts of suburbanization on the water quality of an urban river was completed to detail the various impacts of suburbanization on the culture, economy and environment...
Field Measurements of Landfill Surface Settlements
The Collier Road Landfill, located in southeast Michigan, has been accepting industrial and muncipal solid waste since the late 1960's. This existing landfill encompasses...
Engineering Aspects of Soil Erosion, Dispersive Clays and Loess
This collection of papers deals with selected engineering aspects of soil erosion, dispersive clays and loess. Two types of erosion are considered?surface and subsurface (piping)?with...
Design of Large Steam Turbine-Generator Foundations
This report is a guide for engineers who are responsible for the design and analysis of large turbine-generator foundations. A description of the various components of turbine-generator...
Density Currents in Clarifiers
This paper discusses internal flow regimes associated with the density currents due to diurnal heat loading. The reported studies were carried out with the aid of physical models....
Open Channel Flow Resistance in Horseshoe Conduits
An experimental study of open channel flow resistance in horseshoe-shaped conduits is reported. The friction factor is shown to increase approximately 20 percent in comparison to values...
Hydraulic Design Limitations for Gravity Flexible (Non-Rigid) Plastic Pipes Flowing with a Free Water Surface
Hydraulic design limitations are necessary for gravity plastic pipes when designed for use as a sanitary sewer, flowing part full with a free water surface. The limitation for pipes designed...
Hydraulic Structures on Piles
Many hydraulic structures built in the early 1900's were founded on piles. Today, when these structures are analyzed as 'pile-supported', the analyses...
Parametric Analysis of Concrete Gravity Dams using Finite Element Analysis
More sophisticated means of analyses have been investigated to determine the accuracy and applicability of conventional methods to a range of parameters affecting stability. This paper...
